The 7918 is a heavier-weight filter (367g) relative to others in the Sierra outboard range, which may indicate a larger filter body suited to higher-displacement outboards — always verify fitment before ordering. Because outboard filters differ in thread pitch, bypass pressure, and anti-drainback valve design, using the wrong filter can compromise oil pressure and accelerate engine wear.
