âI’ve run Yamaha for a lot of years now and the one thing that I can say is that maintenance is probably the #1 key to keep my engine running like a fine watch. Make sure you always have plenty of oil, the batteries are charged, and the spark plugs are clean. One other thing, you might want to check the propeller too to make sure there’s no fishing line wrapped in the propeller. Combining all of that can make for a safe and enjoyable trip out on the water.By: Walker Agency
