1976 Gt 150 Changing To A Inboard

[76GT150]

I have a 1976 gt 150 and it is an outboard but I want to change it to a inboard. I bought a 19 ft boat for 50 dollars that has a good volvo penta drive with a 4 cyl engine in it. So I was wondering when I glass the motor mount box's in the glasstron for the 4 cyl what is the best design for them?

I know you didn't ask for this, but I would recommend sticking with the outboard. It is a less complicated mechanism and more reliable to boot. Just the same, hope someone can answer your question.
