The oil filter in your Yamaha 4-stroke outboard performs a critical function: removing metal particles, combustion byproducts, and contaminants from the engine oil before they can cause wear to bearings, journals, and cylinder walls. A genuine Yamaha OEM oil filter is engineered to the correct filtration rating, bypass valve pressure, and thread specification for your specific engine family, providing reliable filtration that aftermarket alternatives cannot guarantee.
Boat Max Online stocks OEM Yamaha oil filters for the full F series 4-stroke lineup, from the F2.5 portable to the F350 offshore engine. Yamaha's OEM filter design includes a built-in anti-drain-back valve to keep oil in the filter between start cycles, preventing dry starts that cause disproportionate engine wear during the first seconds of operation.
As an authorized Yamaha dealer, we sell only genuine Yamaha OEM filters, not generic spin-on filters with a Yamaha logo. Free shipping on orders over $499 to the lower 48 states.
