Hey all, finally found a decent forum after searching forever. Anyway, I just bought a mid-80's 21' Hawaiian jet boat from my buddy, and need some general boat rebuilding info.....
First off, I have talked to the guys at jetboatperformance.com and they are hooking me up with an all new Berkely drive 12JI(?) this winter. My boat has a mid-80's (guessing by the valve covers) 350 Chevy. The 4x4 lumber that its mounted to is rotten on the ends.
I want to rebuild the 350 with a 383 stroker, but am not sure about going about replacing the beams. Is there any certain fiberglass and resin kits to use, or would just regular automotive stuff at Wal-Mart work? And should I run an extra support between the two beams to handle the extra power of the motor?
Also, jetboatperformance told me to build the motor's power range from 2,000-5,000 rpm. Would that be good? I plan on a tunnel ram and a pair of 600 cfm carbs, but don't know if they should be vaccuum or machanical secondaries. And, and and, can I run regular upswept drag headers or do I need water-injected boat headers?
I plan on just playing around the lakes with this boat, and hauling a tube and skiiers around. So no competition or nothing.
Oh yeah, and this was originally a jet boat, but it has been refitted with a stern drive, but they keep blowing apart. This would make the 4th drive in 3 years if I replaced it, but i'm going back to jet.
And anyone know where to find any info about this boat? Its made by Hawwaiin Boats in Huntington, CA, but I can't dig up anything.
Thanks for any and all help!!!
