I just bought a used boat with a five-year-old outboard motor that ran fine on the test drive, but I want to give it a thorough maintenance check before relying on it for the season. I'm comfortable with basic mechanics but haven't worked on marine engines before. What are the essential tasks I should perform, beyond changing the lower unit oil and spark plugs, to ensure it's in good shape, and are there any specific corrosion prevention steps for saltwater use that are often overlooked by new boat owners?
