SIERRA
Four-Cycle Outboard Oil Filters

Sierra high-efficiency oil filters meet or exceed OEM specifications for marine use, unlike conventional auto oil filters. Available for gasoline inboard and 4-stroke outboard applications. High pleat count-more pleats means more capacity and greater efficiency. Epoxy coated inside for corrosion resistance. Shrink-wrapped for rust protection. Some models utilize anti-drainback valves, where applicable.

    Comments about Four-Cycle Outboard Oil Filters:

    Sierra products are engineered to meet today's high horsepower engine demands and stand up in the harsh marine environment. All Sierra products meet or exceed the original equipment part it replaces. Sierra supplies many OEM engine manufacturers and boat builders hundreds of quality parts every day

      Comments about Four-Cycle Outboard Oil Filters:

      I discovered Sierra filters when looking for a Westerbeke 30b oil filter. Having easy access at West Marine solves the access issues with Westerbeke branded parts purchase.
