My boat is a 1988 240 sport baja 24 degree "v" with a 468 engine, un-identified merlin heads ,177 blower @4.5 psi. and a comp 280 cam, water cooled tube headers, currently a 4 blade Bravo 26p prop. It will run 40.0 mph at 3100 rpm and 65 at 4700 rpm running heavy with 75 gallons of fuel and 400 lbs of passangers. This is GPS and the only known facts so far. I have been drag racing for many years on land and can atest that the engine seems to running as intended from idle to wot. Cannot confirm drive ratio. As I slowly trim it out it will not react at all at first then finally gain 1-1.5 mph in a very narrow range of trim setting before blowing out with over triming.
Just for fun, Side by side with a friends newer 1993 Baja 240, shallower "v" lower profile boat, we can run the exact same 3100 rpm at 40 mph but he has a known 502 efi 1.5:1 and a 3 blade 25p, I think a mirage. can't figure this one out ??? I know he is lighter and the hull is easyier to go faster by a bit but wow !!!
#1..On my boat, What is your thoughts as to it's performance ???
#2..Where do you think we can go with mine to make it a better all around setup. I guess I am not real unhappy with it now but know it needs the prop cleaned up and it could be a little faster on top or just more efficiect maybe all around. Comes out well now. Prop is currently a tad ragged on the tips.
