I am restoring a 86 challenger bass boat. I was ready to purchase a 80 mariner tri hull with a 96 hp mercury. Now I know this is a dumb question, you guys know better than I do. Can I just take the motor off the mariner and use it on the challenger? And if so ,what do I have to look for on the transom? There is a 50 hp on the challenger now, but I am not sure if it runs or is locked up. If i can yransfer is it a fairly easy process? Thank you guys in advance .
