just bought it this summer. Want to have it run a little better next year. Nothing major wrong. Because of age and the fact we don't know much about the history (except it was freshwater only)I want to have the compression checked, carbs rebuilt, waterpump replaced. Head pulled and pistons decarboned. Question: anything else I need to do and how much $(ballpark) I live in So Maine. Thanks...........

Why pull the heads? Run a decarb thru it. Or Berryman's B12 or Seafoam. Cost down here for what you want to do, plus change the lower unit oil would be about 375.00 (parts and labor). Do it yourself with aftermarket parts about 100.00
