Hey Jon,
The motors themselves really dictated where the exhaust was going to exit...see the attached pix...:cool:
Gary

Gary, do you know the weight and length vs the 480 hp Yanmar.. Are they relatively close...Also what rpms are you turning and who's multi-speed tranny are you using. Thanks Jeff

Cummins will be at the show...outside of 1350lbs of weight...I got nothing else...

Gary,

Thanks for the pics,.............makes it that much more unique.


Jon

I may be wrong, but I think the 480 cummins is closer in size to he yanmar 6CX.

Any word yet on performance numbers?

Very cool build,, can't wait to the see the performance ##'s

Boat was at X Site today... Played with a lot of different props... The best they found with the time allotted was 69.8mph on the revlimiter - 18 second hole shot - 17x37 5 blades. They said the boat pulled hard - quiet - no black smoke. Overall we are very very happy. They left with 17x39 5&6 blades... Now en route to Ft Lauderdale.

I want this project to suceed in the worse way because I think you guys put this together right and would like to see a diesel boat with outdrives in production that can challenge a gas boat. I think this project can do that.

So, not to beat this to death, too much pitch, not enough prop speed. If it pops on plane fast it's under wheeled for a diesel boat. Your pitch is already too big which means they are not turning fast enough. Less pitch more rpm's.

Joe Gere

sounds like the boat is coming together nicely
