Default Re: Transom Bracket - twin outboards

I agree that you have a prop problem. But I'll also bet you need your whole setup tuned.

Do this test: With the motors trimmed fully down, with no trim tabs in use, while at about 4000 rpms, turn the boat sharply left and right, as sharply as you can. If you get the outside prop ventilating in the turn, you've also got a mounting height problem, for either the motors, or the bracket, or both. (This test assumes factory-cupped propellers.)

Let us know.
