the final numbers

[mattyboy]

got a chance to really run the hornet and get the trim dialed in, best number i could get was about 4400 and around 45 mph on a crowded lake dodging traffic . tonight the lake cleared after a rain shower just at dinner time, with an empty lake I got the boat up to 4900 and 50.8 mph took a bit to find the trim sweet spot . not bad for a small block ford pushing 3000 lbs of boat.

Matty, we all need more power.

Not bad is right.

Nothing wrong with those numbers! Good job!

[Scott Pearson]

You need to Turbo Charge that thing!

Matty:

You've got me beat - I've never tried pushing my Hornet above 45mph or so, figured something might give. I think of this model like mid-60s Buick Rivieras - not the fastest thing going, but a great ride and really cool looking. I wouldn't sweat those numbers.

That's pretty darn tooting for a

Congratulations Matty!

And, please correct me if I'm wrong, but I thought just about every lake in New York had a 45 mph speed limit!

50 makes you a law-breaker!

outlaw I am, yes my lake has a 45 mph limit it just worked out the lake emptied out after a rain storm so I had the lake to myself was cool and calm. I think the weight shifted aft with the replacement tank towards the back helps get the hull aired out some. the ride is so much different from the 16, water that would send the 16 into a skip the launch then slap thingy this thing just crushes. this motor will stay til it goes then modern power is on schedule.

Matty, that is pretty decent in my estimation. My 72 Hornet GPS'd out at 49 and some change. Close to 4800RPM pushing a Solas 21. Original 320HP SBC. It is crazy to put this boat next to my 69 18'. The size difference is incredible! The Solas gave me alot more bow lift and aired the boat out alot more. It made it alot more fun to drive. Still fighting cooling issues with that Chris Craft cooling system. Cools fine when I am up on plan and running 30MPH or more. The minute I slow down off plane, she starts to heat up. No time to figure it out....Too many projects!

Hope you post some pic bet she looked great running out like that

[mattyboy]

yes I want to get some running shots, will need to get a photo boat to run with me.

It just occurred to me , we had someone mention the water passage seals going thru the suspension fork on the volvo as a cause for lack of water and overheat.

Could it be you have leaky upper seal and when you are on plane the force of the water coming up the drive is enough to get the pump water, then when you slow down the water is not forced thru as far and the pump needs to pull the water in more and the seal is letting in air killing the siphon?.


I guess you could check that by adding weight in the back to cover the entire drive in water and see if the volume of water and temp stay ok?

will it overheat if you left it at idle at the dock?

I still am leary of my risers and have my nose tuned into the smell of burning exhaust hose. I peek over the back on a regular basis to make sure I am dumping water.


look Ma no water, you can see the starboard side was dumping no water just steam or well maybe smoke

What kind of Donzi Model is that?

What kind of Donzi Model is that?

It is a custom made model for internationally renowned opera star Enrico Pallazzo

[Scott Pearson]

I thought so...

[Morgan's Cloud]

Matty , is that a stock SBF ? If it is . the numbers are pretty good IMO.
Bear in mind I base that on my experience with the St T with the old stock 4bbl 351W.
Trimable Merc Alpha 1 though.
1.5 gears , 21'' prop and 50mph WOT
BUT I ran at factory recommended 42-4400 max.
Can you run yours at 4900 in its current trim ?
BTW , the trimable 280 drive is da bomb in my books .
