Re: Best way to raise where your motor is mounted?
... or if you don't want to spend $100 you can raise your transom with wood:
A 1-1/2" wide by 2" tall fir filler cut out of a fir 2x4 secured to the top of your transom with 3" stainless sheet metal screws. Then a new piece of 3/4" plywood cut 2" taller than the old one secured to the filler with PL premium waterproof adhesive and 2" stainless sheet metal screws, also bolted through the transom with stainless bolts, washers, and nyloc nuts.
I'd make this new build/modification as wide as thedip down in your transom for strength and not just a little piece to fit under the motor... that would be too weak.
You should be able to build this for about $50 or less.
