As a racing sailor, we pour enough diesel in our boats to get us to the start and that's about it, so-- not much experience with maintenance expectations for a boat like this. This week, I bought a 1998 picnic boat which I have not seen (relied on a knowledgable friend who did tho). She is below-average cosmetically; usually an indicator of maintenance undertaken over the years. 600 hours on her from her original owner. Yanmar 350. I anticipate - and have scheduled - a full run-through for my local Yanmar service yard and a change-out of all pertinent fluids, belts, hoses, impellers. I"m told that a "full jet service" should probably be performed, and that when this happens (off season, after we get to play for a couple months) that the motor has to come out ? And if so, that we should use the opportunity to paint the engine compartment, paint the motor, and pressure-test the fuel tanks. We'll likely upgrade the jetstick control system as I think it's original "old computer" upgrade time. I'm told the full jet service is $3k and the controller is more like $9k What else to I need to know ? Plan to have the wood fully stripped / re-done, pain the topsides, new upholstery etc. Anything else I should know before entering this process ? No, the boat was not surveyed but was fully tested via moisture meter and found to be dry- including the usually suspect bulkheads and stringers Sure appreciate any input from the deep knowledge base here on yacht forums.
