Friend has a 2000 Malibu Escape 23' LSV with the Diamond Hull with a ACME 1275 prop. I believe it has a 350 Chevy engine with roughly 1100 hrs on it.
95% of the time we wakeboard. We are in Houston Texas so no elevation and we put in on a river and are wakeboarding 5 min later, no long runs across the lake so top speed is not important. We run 750lb bags in each rear locker and a 1000lb triangle Bow sac that we probably only fill to roughly750lbs. No wedge
Long story short at some point in the last month it started running sluggish and was fighting getting on plane with the bags filled and 3-4 adults and 4 kids ranging from 30lbs to 60lbs.
He changed his spark plugs, wires and distributor cap. That did not make a difference, so he did a compression check and one cylinder was down to 50psi. A local mechanic believes it is his head gasket.
He is debating a few options -
1) pull the valve cover etc.... and replace his head gasket and see if that fixes the problem and keep rolling.
2) rebuild the engine at a mechanics shop so it will be rebuilt to stock specs and essentially have a new stock engine that came with boat.
3)Rebuild the engine at another mechanics shop that will put more performance parts in it to try to increase the horse power by 40-50 horses.
Now that I have given yall the long story, my question is with that setup in weight and typically wakeboarding is it worth the extra money to rebuild this engine with high performance parts to get another 40-50 horses? Will he recognize the difference? Will that really translate into getting on plane quicker with the added weight in the boat? Or is having the correct Pitched Prop more important than the 40-50 extra horse power? As previously stated top speed is not a factor biggest factor is getting on plane with extra weight and pulling a rider.
Is the 1275 a good prop for this setup? I am not sure of his Vdrive Gear ratio?
I appreciate any input.
thanks,
