Having one issue with my "new" boat that I can't seem to find the fix. It came with a 24# thrust trolling motor which the previous owner made his own mounting bracket for. I upgraded to a 55# thrust Minn Kota transom mount,reversed the head so it works on the bow and it works great except the mounting bracket isn't strong enough and twist. Trying to find a good mounting bracket but can't seem to find one which allows for the motor to be lifted like a regular bow mounted motor. Anyone got a suggestion?

Use the current one and screw some aluminum or stainless steel L brackets to it. That would prevent your twist for sure. As far as something manufactured, everyone here usually builds their own.
