Hey guys,

First time poster here! I have been bitten by the jet boat bug big time. I have been doing countless searches on the net gathering info and such. I am of course looking for a "starter" boat. In doing so I have come across a couple complete hulls minus engines. While looking online I see that 99.9% of jet boats are running 460 Fords, 454 Chevys or 455 Olds engines. I understand that bigger is better within reason and that the big block engines have a little more TQ to them but why is there a lack of small block powered jet boats? I can build a real nice 350/383 Chevy but heck I can't even find small block motor mounts only the above listed big block motor mounts.

LAter,
Tim

That's what I thought...we've had 2-3 go out since I've been hanging around there... :good

Ã‚Â Dependable powerplants.

We ARE having a lot of problems with the Indmar Vortec 8100's (454 ?)...had five(5) go back this season... :eek

Ã‚Â

Ã‚Â 502's & 525's are fine.
They acknowledged the issues and might not going to offer that setup any longer... :break

They even make a 4qt pan for a big block?

Thanks for the info guys. I don't have anything against a big block just wondered what the reason was for not using good small block Chevy's. I am not looking for a boat to break any speed records just a nice solid running boat to have alittle fun with and pull a tuber behind.

LAter,
Tim

Can we assume that he has volunteered to pay all the repair and/or replacement costs. What is his reasoning for the change. :stupid

Not sure...lower profile to fit under an engine cover maybe... :confused

We found it when one of the motors came back to Service and they checked the dipstick...the "full" marker was only 2" from the end.... :eek

They're usually 6"-8" on a 8qt-10qt... :good
