Running 28 bravo 3 props can spin them to 6000 no problem. Need to get some bh props. Handling is awesome. Top speed is already gone over 75 but have not seen tops yet. Still breaking in drive, the thing goes like a scalded dog.

MOP

Like I said every last drop of the bad handling aspects of the 16 will disappear and I was 100% sure it would!

Do a separate post on BH wheels reason being one of the guys in the Maryland area ran a s of BIII's on his BH, he can tell you the speed difference between BH & BIII. The BIII's have more blade area so more then just pitch goes into stepping up to BH wheels. Plus the big kicker I have a hunch next winter the X will sneak up to the right height for the BH. Don Tamm's 18 was left at stock height as he did not want to modify the hull. He gave up about (GUESS) 7-8 MPH being deep, running a very well warmed over 427 SB making a lot of ponies. Steve's 18 at the right height was first classic to try the drive was only a hair off 80 with a bone stock 300 Merc, me thinks in the end you will need custom wheels to get all that little bugger has to offer! You are close to stepping into the "WOLF Pack" arena!

IMO 90+ with confidence is just s few steps away.

Pismo what that drive does for handling it just startling, the boat is riding on rails. Rootsy going over 80 with a SS to me was scary though he did it well, this is a whole different scenario much safer.

It is more when a prop blade flies off or a gimbal or shaft breaks, then you are in trouble.

There is no dought that even with this combo it will run low 80's no gps numbers yet, still testing and breaking in. It accelerates like the wind. Compared to the alpha this is like driving a caddy. Smooth and driveable. Before above 70 it was a flying coffin.

we would actually go in the bay of quinte and yes there are a bunch of ramps real close by as well as a marina that would be no problem to use

the bay is real low because of the snow shortage so i haven't seen anything floating but honestly haven't been out yet

let me know it would have to be in the evenings or better yet on the weekends

A question for the bh experts. What are the accellertion characteristics of the bh powered boat? I am finding that when the throttle is pushed the motor pegs 5800rpm and the boat feels like it is building speed. It blazes from 60 on with a feeling of no end in sight. It also seems that the faster I go the more effiecent it becomes. Is this a feeling of the props slipping and catching up as the props get more bite? The boat will peg the 80mph speedo and still be picking up speed. Running a mod 28 bravo 3 front and just got a 28 chopper bh rear from Mrfixxall which is great. This combo still goesn't hold the motor back. This week comming will be gps week, we will get some real #'s

have your prop guy put some more cup in the front prop,,leave the rear alone for now ..

MOP
04-16-2010, 02:41 PM
Blackhawk wheels! The front prop is 1" less pitch then the rear it feeds the rear, I would wait to try a set of 31's which should get you close. Remember you are a "ONE OFF" there are no other boats to compare. Which the power you are making triple digits may be out there. I have a hunch you may be banging another inch into 31's, time will tell!

I am thinking upper gears also, there may not be anything out there with enough pitch. What is the torque peak and at what RPM, I would try to get down there I think you are too high and will realize more speed getting it closer.

younger
04-19-2010, 03:56 PM
For sure gears have been in play all along. The motor peek torque is probably in the mid to upper 4's and hp around 6grand. I wood like to see max rpm in the 5500 range. I really don't know what my max rpm is as my tach is on the pin. The combo is over the usable reliable rpm range. The motor can do it but a little fast for the bh. I agree there is more speed to be had with true bh props and possibly some gear. The boat is disapointing in that it does not feel as fast as it was with the alpha, but it sure is smooth now.

MOP
04-19-2010, 05:28 PM
I would love to see an 8K tack plugged in, I bet you are way up there. When I was turning 55-5600 I was doing 63 now that I have it down to 5K 65.5, marine likes to sit on it torque peak unlike land stuff that can wind to the moon. A 22BH turns in the 80's you are close to 1K lighter, profile in the wind is far less and wetted surface is under half. You are making more HP then a 22BH you have a ways to go for full potential. I have $100 that says you will tickle triple digits, any takers?

You bet it feels slower having lost ALL the 16's handling and ride traits! You now possess a brand new animal!!!!!!!!!!! Have you noticed trim does near nothing, I said long ago the 16 is the perfect BH drive boat with its built in bow lift!

younger
04-20-2010, 08:28 AM
Trim has some effect it will still hang the bow. But top speed is just a hair positive. I agree mop that I need to get into the meat of the motor and things will happen. The accel. is awsome with this set-up, but need more efficence. Be kind of nice to turn 3800 and be doing 65. Be able to cover some river then.

Looking back into my BH research the BH wheels may not work as well on your setup as they do on the BH, they create a lot of bow lift. Below is a shot of what one member did to a set to reduce boa lift. The BIII wheels make quite a bit of stern lift, it will be interesting to see if you induce porpoising with the BH wheels! In the picture notice how much was scalloped out of the front prop. If I remember correctly this was done at Lake X by Merc for one of our guys!

Sounds like a cool project boat, good luck. I couldn't open the video but if you send me some pictures of the transom on the trailer I may be able to help.

Here is what I do know:

1) Hale does a great job of taking stock BH props and fine tunning them to your actual performance numbers. Adding cup, changing pitch, reducing blade area, etc...

2) The X dimension is very important for the BH!!

3) The X dimension is very important for the BH!!

4) the trim of the drive once planned has a "sweet spot" once you go past it you can feel the boat slow down, trim it back down and leave it. Once you find it leave it there for the rest of the run.

5) Rocker plates will help you on the short 16 hull

6) Reinforce the stringers, transom, and motor mounts you will need it in the long run

7) The X dimension is very important for the BH!!

Trust me...

As a resault shea and I ran the 31's 80.7, Still some left was starting to wiggle. Feels like it is falling off the keel and gets into a hull slap. Have about an hour and a half seat time with this combo. So with some time I have no dought it will run mid 80's. Was showing 70 mph @ just over 4000rpm. Shea was on the gps and gauges. At 70 it is as smooth as silk. So the tweeking begins!

MOP
04-24-2010, 07:14 AM
Everything will change once you raise the X and get the gear case clear of the water flow, IMO you will lose some the current stern lift and gain several miles per hour and I believe some stability. Steve's 18 which Tom setup rides on rails and like he said does a hair under 80 with a stock 300hp Merc. The BH wheels induced a little wiggle, that can be worked out by Hale. I wonder what the available pitches are for the BIII XR, that may be another route to explore. At least you would have stock items rather then custom.

Phil

younger
04-24-2010, 08:30 AM
Sorry MOP the X is going to stay! The only reason for this is a stock appearing 16. If I have the to go any faster another boat will be the route to go. I understand the thought of extracting all potential, but running 80 in the 16 is fast. Even with the bh and the stock location the handling bonus has been well worth the experiment. Driving this thing reminds me of the day's I was running outboard hydo's. There is a real feeling of speed!

glashole
04-24-2010, 09:09 AM
boat works real good

honestly couldn't have seen being comfortable in a 16 at 70 mph but it is like it is on rails

awesome boat , great addition to make the 16 usable,

none of the customary 16 traits

it doesn't hurt having the monster motor that he does, but i would assume a smaller motor would still benefit from the drive as well

the boat has more than 80 in it for sure but we were running out of hull

the hull slap it the only thing holding it back

good to meet up again, look forward to doing some running

The motor is producing an estimated 475 hp and 525ft/lbs. With my 28 props front being a bIII and rear a 28 chopper bh spin 6000 easy. With sheas 31's never got to see max rpm boat gets into a hull slap. This is due to the stern lift I suspect. With the 31's it is super effiecent.

Just an update. I'm waiting on a set of Hoss props from Dave Bostic who as we know help develop the BH props for Gary Eisenburg at merc back in the day. I have gathered some interesting info from him. The first was prop timing. He had mentioned that the 180 degree method that merc uses is just a genaric. Dave told me that the front prop blade does most of its work in the first 90 degrees of making contact with the water in surfacing cond. and to time that with the rear. He also said in some situations the front prop thrust will hit the back of the rear prop blade. So to time the props so the rear picks up the front thrust at the right time. So today I set out to trial this, with good resaults. The rear prop was retarded in the factory setting, so I advanced it two splines cw. On the water test netted me more speed per rpm. I did not do a full throttle blast as these are my 28's and buzzing @6000 plus was not needed. I wanted to see if I would pick up mid range eff. And this was a for sure. It would cruise at 70mph in the 5000 plus range. This may not sound great but it is better then before. With this prop set before it would be doing in the 65 range and would have to spin 6000 plus to do the 79.4gps. Another intrest was x-dim. I told him my drive local and he said I was 2" low. Yes MOP. Yes MOP. One of the main reasons is as the boat tries to lift the bow it pushes the drive down which is so far back the bullet is now pushing on the surface or just below , it is being forced down creating stern lift. If the case is higher you don't get the same push back or stean lift as when it is lower. And as a resault with the drive at the correct x these forces are minimal and less resistance for greater top speed and handling. With this being said Dave told me that with some prop tweeking with the lower x it can be helped. We wait and see!

I'm curoius, I talked to Hoss last year (not sure who) and I thought they no longer made bh props. Is Dave Bostic still at hoss? I run a bh with a bravo x dim so I'm looking for a prop to help with the deep x.

Dave is still the owner of hoss and I just got of the phone with him 10 minutes ago. The props I have ordered get shipped out tomorrow. These are a set of 30" divelopemental props he has tweeked for me. He has tailored them for my app. in regards to my x-dim. So I hope to see then in the next week. Dave is a pleasure to talk to and has been very helpful to me. If the props do as designed I sould easily see mid 80's. With some seat time and some playing the bIII and chopper comb. I have the boat is running low 80's now. In my app. this drive system is unreal. I can't say enough for the handling an speed.

Along with striat cut gears up top and big bearings to carry the load. I can't say enough about this package I have put together in the 16. It was 2 years of work and research and convincing. Thanks again Phil. I owe you a ride. Bring goggles:)

I knew that it was a good package, I held on to my BH drive with the same intent but just did not have it in me for another project and the funds that go with it. You have no idea just how tickled I am that you finally got it together, I know it will just get better and better. Next year raised X and more propping you will tickle or pass 3 digits. Phil

don't get to far into it

the x dimension isn't perfect but it does work

ride in the boat first Phil, works great but doubt it will be a safe 100 mph boat
get a set of K planes to control the hop and it will be a safe 85mph boat though

Received my new hoss modded props, they are on and waiting testing.Hopefully tomorrow. Rained all day, so no boating.They look like they are going to be trick. Dave played with them so the boat would ride flatter. The cleaver design should help. Front prop 16.5 " in dia. progressive pitch to 29". The rear is a tweeked 31 bh. Will post the resaults.

The stern lift is what bothers me, makes it run to flat. My 22 with the high Tempest X went very flat over 40 killing top end, I could get a couple of MPH extra in the right chop. But the chop could not be to tall then the wheels would be breaking loose to much. Steve's BH 18 ran quite well in a chop so the 16 may also, but the raised X is still key!

1) No on the K-Plane use Rocker Plates, less drag, better ride attitude adjustment.

2) Too much Cleaver creates stern lift, better with rounder ears to bring the bow up.

3) The correct X dimension will eliminate the bow lift issue and any bow slapping.

4) The only part of the prop that should be in the water is below the hub (just blades man:)

Trust me...

The boat does not need any more bow lift. The testing of these props will tell the tail. I understand the x factor and the bh design. I wanted the boat to stay in a stock configuration. So when it is in the water it looks like a plane jain 16:) The x is been altered some when I put in the new transom. The engine sits as high as it will with the stock hatch. When I had Dave Bostic do these props I of coarse gave him all the spec and detail of the boats handling. He did agree that the x could come up a touch. He said that he could tweek the props to help me out some. Time will tell. I plan on testing as soon as the weather gets good. We have to realize that the speed of this thing is running now is crazy. After a run I have to wipe off the back of the boat because it is covered with drool and tears that have blown off my face. So far with my 28 the biggest speed gain has been seat time. I have run alot of different performace boats and this is a totally different animal. There has been a few people that have gone for a ride that are quite familure with perf. boats and will never get in again. My best passenger is my wife. We went for a rip last week and I was into the 80's I take a look back to see if she is still there and she is sitting cross legged on the back seat and not even hanging on to the rail. It reminded me why I married her:nilly:

You have found yourself a good woman there. Reminds me of Steve Marr's wife Suzie. Steve would have the 18BH WOT flying through the air and she would be sitting there with a glass of wine in one hand and a cig in the other!

Sorry about the bow lift, I thought you said you were not getting enough. I would like to drive it sometime and see how it compares to the 18.

Do you have any tabs on it now?

Did you find the sweet spot on the trim? It might have different caracteristics with the lower X, but the X18 had a noticable sweet spot in the trim that if you went past it you could feel the boat slow down. Then if you trim it back into the seet spot thats it you can just leave it there for the remainder of the fly. The X18 has no tabs so once its trimmed just hold on to the wheel and open it up.

Congrats on a cool new addition to the high performance Donzi Family. Its cool to have such a sleeper boat. Kind of like Mighty Mouse running in the NY city poker run and smoking all the big boys out of the gate!

Be safe out there, and come to Winni for the poker run at the end of July. Its a great run and there are other 16s that do the run with us. Its a great lake and a great gathering. Hope to see you there.

Got to try my new 30" props. The mid range was awsome. 3000 rpm 45 mph 3350 52.7mph not bad to cruise. It was scarrrrrrrrrry fast, no idea the handling was offside. I was hitting 70 plus and was hardly over 4300. I gave a few quick pokes on the throttle and the motor had no problem pulling them. The boat would air out so much, I could trim out as far as I wanted and the props would not brake loose. The front prop has to much dia. As a test I cupped my 28 bravo III and ran it in front of the 31 cleaver. I was able to maintain the mid range, with running 74.1 and lots left. Had the wife and boy so I ran with some sence. The boat is no longer for sale. It is just way to much fun. Going to run the river on Sat. the poker run in Alex Bay NY. See if we can tag along.

I have been playing most of the week with the set -up. And the greatest asset of the comb I have put together is not how fast it is but how effiecent it is just some #'s. @ 2800 rpm it is going 40 mph. It cruises @ 3500 running mid 50's and @ 4000 it is running 61. It will run 70 @ 4400-4500rpm. I have yet to been able to max the motor out to confirm a top speed, but it is fast. The props from Hoss have been great I give the trim button one quick press and it is set. The props have created lots of bow lift. The only draw back is I have lost my rooster tail. But that is a resault of the props effiecency. Very little wasted energy. All the energy is in forward push.

Just a quick update on the bh 16. Ran the St. Lawerance today and was able to squeeze some more out. She was turning 5450 and almost pulled 85 mph 84.4. Three in the boat and 30 gallons of fuel. I think that if I get perfect conditions 85 might be there. I was running on smooth water. MOP you missed you ride this past weekend. The river was rough could have given you one great ride. Next time.

I have been wanting to get one last run in before the winterization process begins. I would like to make a run with low fuel and no interior and ride solo in some cold choppy water. If it works out I will get my little man to shoot some vids. See if we can get it into the over 85 club.

Here is the last run of the year. Was hoping for some mph but there was to much traffic and rouge waves. 77.8mph. I was never able to stay in the throttle any more than 25-30 seconds all season long. 84.4 is the fastest this summer. The boat also does not run well light, the fastest speed was with full fuel and 3 people. In the video I pulled the interior and ran 1/3 of a tank of fuel. The boat gets supper floaty above 80 and I have put many many hours on this set-up testing. The bh has been a great addition to this boat, with my 30 Hoss props it runs super eifficent. The boat has been a major sleeper. http://www.youtube.com/watch?v=tKFdmf5i4Ow

It is kind of weired that this boat started out as a 4.3 omc doing 52-53 and that was fun. Then the 350 alpha combo for a couple years topped at 68, along came the 415 alpha, and I hit 72mph and I thouhgt that was great. The handling was rotten with the larger motor and alpha. Yanked the motor bolted on the bravo transom and bh and have ran best 84.4mph. There is more in this combo no dought with some x-dia changes and a set of 31's. From my point I would say it would run around 87-90mph. We are all after more but after the progression of this boat I have to say 80 mph in a 16 is smokin! I think that if I plan on going any faster it will be in something like a 22. Wife would like a 22 with a 572bbc, aluminum headed roller motor, imco shorty to match her donzi tattoo. I would think that would fill the need for speed.

Greg Guimond
11-30-2010, 01:12 PM
Interesting provenance for your hull and at 85 no doubt the fastest 16 in the world at present. The thing I found amazing was the BH's smoothness. When you add the super flat attack angle to that it kind of makes all the 16 "drama" go away. Many on this board have said that, but the video really spells it out. Places a very high bar for the rest of us! There is some equation that spells out what is required for each additional 1mph above 80 in terms of power and I think it pretty much sends OB lovers like me back to the ..................

Thanks Ken. Yes I still have the boat. It is for sale. The motor has not been dynoed so the numbers are an estimation of previous sbc I have built. It is a conservitive 475 hp. The boat is over powered and muscles its way to the 80's. I believe that there is more, but I seem to like earth right now more then making a trip to one of the other 2 places of after life. The boat pulls the 30 inch props like a drag car. My goal when building the boat was a 80mph stock boat that was good on gas and reliable. It is all these things and more! People ask all the time if the 16 has more with this app. at different x ect, but from my experience my perticular boat has a terminal velocity of about 75mph. After that it demands alot of respect. My thoughts to its limiting factors are the rounded keel at the transom rounded edges at the transom and lack of hull length. My x is low by about 1 inch, and does this contribute to the lack of control at 80+! Some but not as much as the shape of the short hull and rounded curves. For example craigskilling runs a 18 bh 383 with same x less power and runs strong. I am faster but cannot stay into it at the 80+ speeds for extented periods due to control issues. From what I have seen running with him, his boat will not get into the tempertantrum at the speeds I do. And his boat is fast and will get faster with some props. When I had my props built for this app. the x was taken into account and the late Dave Bostic worked some magic. At the speeds I'm running the wetted surface that the boat is running on is like a canoe bottom and the transom is creating suction from the rounded edges. As I mentioned before that I want the boat to look completly stock, no scoops, no moded back seat for the extra 1 inch raised x because of space.

Thanks for the kind words Norm.It was great running side by side that i have on video,I must get that up on the Reg.I agree that my 18 feels great all the way to 80 it feels solid and wants to go more just need some more prop.I have a chance to buy some 29 but i might be the raise of the X this winter so i think i might need 31.should be interesting next year.

Craig get the 31's on before the end of the season for testing and that will awnser all the questions. As far as the raised x try the props first! I say you will run low to mid 80's with the 31's. That willl be lots fast enough!!!!!!!!!!!!
