    What boat?

    The bh 16 may be comming apart. An the question rises what could I put this drivetrain in? 415ci sbc aprox. 475 hp @ the crank maited to a blackhawk drive with 30" props. The boat that it goes in needs to run rough water, and get as close to 80mph as possible. Some of my first thoughts would be a retired svl race boat like a Extreme or Phantom. Lite boats, stepped hulls, could one of these be fast enough? Some of my other choices would be a 24 stepped Superboat or their 30 y2k. Another was a 21 Sutphen, 20 Cig, or possibly a 21 mtr Cougar or Eliminator 21 daytona. The last two would run but rough water? Last tought was to sell engine, buy 22 classic and build a 540 bbc 675 or so hp and bolt on the bh. Anyother ideas or thoughts would be great.

    Your all over the board there Younger with hulls. Is rough water more important then top speed? Forget a Superboat 24 or 30 with a SBC.

    Right now considering any and all boats. Greg do you have any time in either the 24 or y2k. John Coen has said that the 24 will run in the high 60's with a 300hp sbc and the y2k will hit low 70's with a 496ho. The sb I have is not your average rebuilt truck engine. The 475hp is on the conservitive side of things. I have thought that going to a more modern design that has stepped hull or pad would possibly put me in a larger performance hull and still keep some of the speed I need. Also I like doing things a little different, just like the 16 BH. I have met the goals that I wanted to with the 16 and time to move on. Please if you have any +/- on the Superboat please inform. Hell I have thought of even putting the 415 in a Jersey skiff and buzzzzzing the crap out of it!

    I owned and drove a 24, was not that impressed with the overall ride an handling but Coen made a variety of mods over the years. I also owned and drove a 21 Super. I guess the first thing is to figure out what you want the overall length to be and do you want a sit down or stand up hull. From there the options start to present themselves.

    Greg I have only seen 1 Superboat up this way it was a 30 y2k, lots of 24/7 hulls that are similar to the SB 24. A fellow I know has a 26 martini that runs 113mph gps wich is similar to the SB. The info that I have read about the Superboats implied that they were fairly fast with conservitive hp. Correct me if I am wrong. Was yours o/b or i/o? What speed and what year hull? I'm pretty loose with my requirments but, ideally the boat needs to run 2/3 footers, be in the 80+ mph range with my power and be safe. Have you had good luck with your o/b merc's? I have also thought if I moved the powertrain I would go 21-24 skater route. My last o/b was a B class pickle hydro running a merc 25 hurricane on quicky mid and lower. So to say the least old tech. My wife wants a 22 with a 540 so we will see.

    I think you would be surprised at the ride in the 20' Cigarette in rough water - great boat - . As far as speed, I don't know since they take some power to run the relatively heavy 24 degree hull. I loved the one I used to have. The 21 Daytona would get your best speed, but it is not a good choice for a rough water boat. I have not run the other hulls you mentioned. Bill

    One thing I would need some insight into is can you put that BH drive into just about any hull and be happy with the handling dynamics. This I have zero experience with but I would assume for example that running the BH on a 25 degree deadrise V like the Martini 25 ( I believe the 26 your refer to going 113 is actually 25' like Bill's) would not be a good match but I have no idea. How does a Martini 25 get a 113 GPS reading without a surface drive? It might be one of the best 25 footers ever designed.

    On the Cigarette 21 I/O, Bill did that hull have any small pad at the end of the 24 degree V Bill?

    Greg,
    I too would like to see a 25' Martini doing even 100MPH -
    The 1975 20' Cigarette I ran for a few years had a rounded V like the Donzis. I had a BBC making around 450HP and I believe 65MPH was what it ran with the TRS drive. It would really take the waves well. Bill

    Thanks Bill, that is kinda what I thought. Here is a pic of what I believe to be a Cig 20 transom. I am not so sure that this bottom design would work well with a BH drive but again I have zero BH experience so someone else would need to chime in on that aspect.

    Younger, I think your looking for a 23 footer with at least 22 degree V and better yet 24 degree with a small pad, no more then say 7". Make it a sit down hull and keep the beam narrow and you will easily get 80mph and still have all the benefits of the plush ride. The taller the freeboard, the more wind you have to push remember and 80 will become tougher and tougher. I think 24' is not needed so I'll say less then 24' or greater then 22'. There I just spent your money LOL

    The Martini has a blown bbc made by Ferrara hooked to a # 6 drive, a set of massive tabs. At around a hundred it gets silly but drive through and settles on the tabs and tops at 113 gps all day. The motor makes huge power.

    Wow! What an awesome setup. I would sure like to see a video or a few pictures of that Martini. Bill

    Blower motor and a #6 ..........now I buy 113. It is amazing how much extra gunnel and deck height creates resistance and the Martini 25 is a true blue water hull as Bill can now attest to. I'm betting 800HP range to get 113?

    Younger, aren't you up in Canada West? I have to believe you would have a ton of options out of California region in the < 24' range. Now finding the deadrise needed may be a little tougher in that neck of the woods.

    Greg I'm located in Kingston, Ontario, Canada. I am located 45 min north of Watertown NY. Most of my boating is on the St. Lawerance, Lake Ontario, and the Big Rideau Lake. All these waters can be unfriendly at times. When you mention west coast the boat that pops to mind would be a Schaida mini offshore.

    Ok did not realize Canada East. In that case California boats may be tougher to make sense of. I'm not sure what you mean by Schiada Mini Offshore, I never was aware of that model. I would suggest a Howard 220 Offshore. If you find one that is 1997 or later they added a pad. That boat is 22'4" and runs 68mph with a 385HP BBC and Bravo even though it is an 8' beam. It is 22 degree deadrise but the bow entry deadrise is very steep. You could also look for a Warlock 23 World Class Offshore. That boat is 23'6" and is a no pad, 24 degree V with a 6'6" beam so the bugger hauls the mail. The Crusader on the board is the early version of that hull. Very dry hull with the strakes running right up to the bow which knocks down the water in heavy 3-4 foot rollers. Last from the west coast would be a Vaughn 22. This hull took the Schiada 24 and splashed it so the bow entry deadrise is 50 degrees and hardcore for heavy water. All of these boats are sitdown boats that will run with much bigger 24x7 hulls in heavy water and be a lot faster when things flatten out. All 80+ with your power easily.

    Before your retire that 16 BH be sure to clock a high speed run. I'm pretty sure you will break 85.

    All of the above hulls will snack on 22 Classics and 24 Superboats...................
