I can't believe I'm doing it, but I'm so busy this year, I'm actually paying a shop to winterize my boat, $70. Well I have an interested buyer who may want to come up and look at it. I know that I would want to take any boat I'm buying for a test run. What I fear is that he'll run, then perhaps drag his feet for weeks or not buy it at all, and I'll have to flip another $70 to rewinterize. Should I ask him up front for the $70 deposit as insurance. It would help keep the tire kickers away. If he buys it, the money goes towards the purchase price. Sound fair????
