Yesterday we went over some basic post-outing maintenance, which is essential to keep your engine running smoothly on a day-to-day basis. But for longevity, you’ll want to also go through a more extensive maintenance routine periodically. I do this routine about once a month during the season and when putting my boat in and taking it out of storage.
First, check the fuel and Yamaha 2M oil in the tank to ensure there isn’t any water in it; actually, I do this before and after each outing. Inspect the fuel line for any cracks or signs of wear and corrosion. The fuel primer bulb obviously should not have any cracks, and it should also feel pliable. Examine the fuel tank for damage and ensure the tank vent is aspirating properly.
