Yamaha Marine Oil & Yamalube Products

Yamalube is Yamaha Motor Company's proprietary line of marine engine lubricants, developed in parallel with Yamaha's outboard motor engineering program. Yamalube oils are not generic marine oils, they are formulated to the specific viscosity, additive package, and anti-corrosion requirements of Yamaha's 4-stroke and 2-stroke outboard engines.

Boat Max Online stocks Yamalube 4M 10W-30 4-stroke marine engine oil, the correct specification for most current Yamaha 4-stroke outboards including the F series. We also carry Yamalube 2M 2-stroke marine oil for older 2-stroke Yamaha engines. All Yamalube products sold by Boat Max Online are genuine Yamaha products, not third-party reproductions.

Using genuine Yamalube oil in your Yamaha outboard ensures compliance with Yamaha's maintenance requirements, supports warranty coverage, and provides the corrosion protection and lubrication performance the engine was engineered to receive.
