20-Hour Outboard Motor Maintenance Checks | BoatUS

Benny Quinn, Master Yamaha Technician at Annapolis Boat Sales in Maryland, shows BoatUS Magazine's Lenny Rudow how to perform a 20-hour maintenance check on a four-stroke Yamaha outboard motor. This checklist includes all the items you would do before every outing -- checking the oil level; inspecting engine mounting bolts, cowling vents, telltale, prop & skeg; plus a couple of additional steps, like adding a gasoline stabilizer and an on-the-water test. *BoatUS suggests always following the boat or engine manufacturer's maintenance recommendations for service items and schedule.
