Before we delve into the maintenance procedures, I have a quick caveat: Unless you are a mechanic, have a professional tune-up periodically. It’s good to have a grasp of the basics like changing your Evinrude XD100, but an expert mechanic is sure to detect some problems before you do. Their routine should include a pressure test of the lower unit, testing of the spark plugs, seals and pump, and a comprehensive examination of the rest of the components. Trust me, it’s worth the time and money to nip these systemic problems in the bud.
One of the easiest ways to maintain the integrity of your engine is by flushing it after each outing. Admittedly, sometimes I cheat and go an outing or two in-between flushes—do as I say, not as I do. Salt water is particularly corrosive, so there are no exceptions here. Tomorrow we’ll go over some basic checks you can do for the 10-15 minutes while you are flushing your engine.
