I recently purchased a 1989 Maristar 240 with a 454. The boat has a 1:1 gear and a OJ 13x15 4 blade prop. With this setup the motor will only turn 3000 rpm. I know it is overwheeled, but what should it turn with that prop? Could the prop be holding it back that much or should I start looking for other problems? The boat seems to run fine otherwise. Thanks in advance. Any insight would be greatly appreciated.

It does about 35 mph on gps at 3k.

this is probably a stupid question, but is there a trick to spinning one of these boats out?

Hanging on!

Never done one in a big v-drive so they may not spin as easily. I know in my Prostar it is easy. 30++mph, Hang on, spin the wheel hard right and cut the throttle. Boat whips around faster than you can think.

I thought that's what was meant, but in a 240.....?? I'd watch....;)

I use to spin-out my '94 prostar, but I won't do it with my 230VRS. I would advise against it with yours too. With a v-bottom on a larger boat, engine in the rear instead of in the center you may take a risk of rolling it. Plus it's hard on the running gear (strut, shaft, rudder, etc.)

The '89 Maristar 240 was a mid engine DD model, big, heavy and had no tracking fins IRRC, not a V-Drive.

OOPS! My bad! I thought it was a v-drive. I still wouldn't try doing spin-outs with it though.

Yea, I know, I've driven a friends '90 MariStar 210 DD and it won't turn in a 40 acre field, leans real bad like a I/O, but the ride is nice compared to our '89 PS190.

I am sporadic on this site but have a 1989 Marisatr 240 and are living a nightmare.... We just had new engine completely rebuilt. New everything. They guy who built the engine suspects it has closer to 525+ Hp now. Was the 425 high performance engine.
Went to run it and work out fine tuniing with the mechanic who installed it. We got it running and then went to re-start when hot, and it was sluggish, then continued to slowly turn over, even when key was off... then smelled burning battery leads...mechanic said solenoid was stuck open and starter did not have enough power to turn over higher hp engine...he was rotating new electronic ignition ditributor cap for "easy start" during this entire event. Took off starter to have it checked out and is convinced that is the problem. I am not so sure since about a year ago we had the starter completely re-built and had not used because engine went bad.

I would suspect, the old rebuilt starter just doesn't have the umph to turn that engine over. I would consider a new starter or trying to find a hi-performance marine starter for large high compression HP engines.

I would try our 13 X 12.5 LC 1" XMP 3-blade. The 13 X 15 LC is too much prop for your application. Give me a call with any questions.
