Re: omc tilt bracket
Mount the bracket as high as it will go, using the botom holes in the bracket. Then, you'll have another few inches to go down if you have to.
The top of my OMC bracket is 24" above the bottom of the boat and I use a short shaft. I wish I had a little more upward movement.
So, in proprtion your starting point will be 5" higher than mine.
Everythig is a compromise. When my motor is down its too deep in the water. When its up it still drags the prop at idle. 11" vertical travel isn't sufficient unless I could move the bracket up a few more inches..
