Very cool indeed. More pics, more information!

Dang those things are smokey!!!!!! Sweet boat!

shifter

The motors weigh about 1800 lbs.
That is an older type the new ones do not smoke as bad. Direct injection will cure that.
Run the exaust under water, it helps.
Just think a little more boost, more fuel = 1200 hp. hmmmmm. What smoke.

oh I forgot that 750 hp is 1600 lb/ft and at 1200 it is around 2100 lb/ft

Yes That is correct the engines are as shifter says, they are coupled to crashbox es with overgear 1,22. 1

and the drives are trimmax, one bad thing about the trimax drives is that they are not so easy to trim up and down, due to the short axleshaft. On this boat.

so we are going to take the boat up tomorrow and lower the engines so we can trim the drives more up.
for more bow lift. as you see on the pic it goes kind of flat, an due to that we lose speed.

The engines and drives was bougth by fabio buzzi him self, and he said we where insane if we put both engines in this boat.

But he said if we got the boat and engines tuned in, it we go aprox 105mph, so we was kind of disapointed with the speed.

here you can se that the we have no bow lift.....

That looks sweet. I hope you do get more speed out of it. I would like to do a similar diesel project (on a much smaller scale though.) Keep us updated.

Any chance we could get video or a sound clip!

Groove, What make of power were you thinking of for your diesel project?

leviathan

shifter,
I think you'll find all the seatek's are 'direct injection' and 4 valve, I dunno what model they have there, but the earlier 7.8 litre smoked like a trooper when cold, which I think is in part due to them being a lower comprssion ratio, those motors were quite 'stressed', and made IRO 900hp in race spec,
the later 10.3L's are as you say, much 'cleaner', in race form the 10.3 are regulally run at 1300hp, but require a lot more 'quality time' back with seatek as a result.

Since I don't have a extra money, I originally thought of a Cummins B motor. I love it in my truck, they have been around a long time and hold up well to modifications. I am concerned about weight though. It ain't no Yanmar.

I was thinking a 27-29 foot boat with a single surface drive diesel would make for a good cruise speed and easy on the wallet for gas. The only problem is the first time I get passed and want to crank it up a bit... Diesels typically have a great cruise speed but top end is just a small fraction about cruise.

That is unless you put in twin 750 hp torque monsters!

I found a guy who is working on a single Cummins diesel in a Warlock. I think it will be slow for a cat but it will be interesting.
