Re: how to convert 15" transom to 20" on Alumacraft T16-XL?
It all depends on how you are using the transom. If you're looking to just raise the motor then you could build a simple riser block. If you're looking for more splash protection you can build a full transom all the way across. I think to do it right, I would take off the existing metal cap, take out the original wood, then put new wood in with a 5" rise.
