I have an old 1989 Malibu Skier ski boat with a Mercruiser 5.7 (carb'd). I believe this is basically a chev 350 with a bit of dress up for a marine environment including water jackets for the exhaust, add'l water pump, etc. It has iron heads and an iron inlet manifold and a carter carb. Supposedly it puts out 260hp, and it certainly feels it.
I'd like to get some more hp/tq out of it. I'm thinking better alu heads, a different cam, and a good alu inlet manifold should get this thing above 350hp. As is, it scoots my boat down the lake at a solid 47mph and will rip any water skiers arms off who wants to try to hang onto a WOT start. I'd like to be able to get above 55mph, and I think 350hp should do it.
What do I do to this engine to get it cranking out some more hp/tq? Anybody here ever hot-rodded a mercruiser engine?
Thanks.
