Transom Bracket - twin outboards

[Old'sCool]

Lobo, You got me thinkin'....

My single (on aluminum 30" setback bracket) cavitation plate is 3" above keel. This mounted in top bracket hole, 2nd hole down on motor.



Looking at your pictures and thinking here, I believe your foils are acting like sails against the water when coming off a wave and preventing the motors to go "under" water momentarily, allowing the props to have little or no water to "bite". I believe setting the cav plates correctly, removing the foils, adding (or changing) to a cupped prop (and probably 4 blades) will help tremendously.

One more afterthought....

I had the pleasure of running a 23' Triton w/twin 150 HPDI's for a few seasons. Those motors ran best when mounted "goofy foot", opposite of yours.
