When running the boat tends to lean to the stbd side, the faster I go the more trim tab I have to use. The drives are at the same level. Any thoughts?

Are your drives counter rotating?

Tom, I don't think so boat acts normal otherwise.

Thanks

They should be counter rotating. The props should spin in opposite directions, probably outward. If they don't, this is likely cause.

Griff, I understand that if they are spinning in the same direction this would cause the boat to act this way. If I have a left and right prop on and they spun in the same direction would this not rob me of a lot of speed?

How about posting what boat and driveline as well as anything else you can describe your setup by? If you had "left and right" props on same-rotating drives, you'd be going in very small circles. Leaning would be the least of it.

Not if you were trying to go in a circle. I think what he is trying to tell you is to make sure your props turn in opposite directions.

perform330

Yea, the turn opposite. Thanks

Griff

I suspect you have a hull problem, like a bad hook, or you have a bad gimbal ring(s).

PARADOX

Sounds like you might have a hook in the hull, or something in the gelcoat/paint to slow the strbd side. Also possible that the RPM's are out of sink.
Stupid question may be , but "props are same pitch"??
