STEF'S Marine Competition Wet Sump Oil Pans have emerged as the leader in oil pan design for the offshore power boater. The unique blending of well proven horsepower producing design along with uncompromised construction and the utilization of our proprietary “Marine Environment” baffling in the sump area has elevated us to the industry standard. These elements of design reflect an ongoing research and development program with top engine builders, boat builders, Riggers, and Race teams to provide them with race winning performance.

The Competition Marine series is constructed from steel, stainless steel, or .090” aluminum. Regardless of material used, these pans are 100% heli-arc welded inside and out to withstand hours of crashing through 6 footers at 120MPH. We incorporate our fully extended maximum kickout design with Teflon coated uni-directional windage screens to take full advantage of all elements required to control windage for maximum horsepower. Our proprietary design of trap doors and baffled sump areas insure an ample supply of oil in the pickup area.

All Marine Competition Series pans must be ordered with matching pickup/pump assemblies to insure proper fitment and fatigue resistance to vibration. For ease of proper maintenance we also incorporate a dipstick that has been designed to give ease to routine fluid checking in the marine Environment. Mounting hardware is included with pan.

We are also proud of our continued association with A.P.B.A. Inboard Racing. This alliance has expanded our knowledge of class racing through personal involvement and a true race site education!
