4-Stroke Outboard Maintenance Check: 50 Hours | BoatUS

Benny Quinn, Yamaha Master Tech from Annapolis Boat Sales, shows BoatUS Magazine editor Lenny Rudow all the things you should check on your four-stroke outboard engine after every 50 hours of running time, in addition to what your owner's manual recommends. Items include checking the oil, adding a fuel stabilizer (particularly with ethanol fuels), replacing your fuel-water separator, checking fuel hoses for leaks and cracks, checking mounting bolts, inspecting your propeller and skeg, looking in the cowling for birds nests, ensuring your telltale is putting out water, and testing for max RPM.
