About the same as a car, new oil, new spark plugs, new water pump, new spark plug wires, some stabil in the gas to keep it from going bad, maybe a new prop if its bad, that's about it without rebuilding the engine if its not broke then don't fix it. I'd also get a shop manual it tells you everything you need to do.
