I have a 1992 201 that I am planning to start working on soon, the bottom right motor mount bolt has the dreaded "brown stain". The transom feels solid and does not move when I jump on the outboard and there is also no stress cracks on the transom/splash well area. i've read several posts where guys "dry out" the transom using heat lamps. Question is can I simply remove the outboard and do the heat lamps from the outside or is it more effective to remove the gas tank and do the lamps from the bilge? Also what distance is best to keep the lamps off the transom without causing a potential fire hazard?
