I just bought a 1988 Beretta Success that has a Cantilever Hung aq131 with a massive hole in the right side of the block. I came across another boat for next to nothing that has am aq171 that is supposed to run so I went ahead and grabbed it. My question is I know the 171 is around 150# heavier than the 131, so would my transom support that extra weight or should I go ahead and fabricate some forward mounts in the hull? Thanks all
