Default Re: Transom Bracket - twin outboards

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.

open to all suggestions but the motors actually got a little better with the addition of the foils. however, they are easy to put on and take off; these newer ones do not require drilling holes in your motor - just have to loosen one bolt and they are gone.
the motors are supposed to go up two holes today and hopefully I can get it out to see what that does tomorrow.
will post when I have something new.

I REALLY do appreciate all the ideas!

when you move thim put thim all the way up, I dont think with where your bracket is mounted you can get thim high enough and keep the hydrofoils for my 150's with thim
on I can cruse at 3100 when rough without 4100 is the slowest they are made to run on top or above water

With the nearly 1000 lbs of motors hanging 2+ feet back you may very well need the SE foils. They certainly have benefits. I meant to edit that... Good luck, it looks like you're on your way.
