Should I buy a boat that has been sitting in storage for 15 years?

I've never been in the "run away" category, just rightly skiddish about the condition of the motor. The OP also needs to consider the price obviously. Whatever it costs, if he doesn't have much spare money available for potential fixes down the line...that could be a problem.

This could very well be a gem of a boat. Without more info, none of us will ever know.
