Designed for multi-engined all-out racing, as well as, jet drive boats used for skiing and recreational uses. Built from super heavy duty 16 gauge steel to withstand all types of abuse and severe racing conditions. Designed with Ale bilge clearance in mind, as well as 100% oil control as a priority. This pan's full length windage tray and double trap door system provide complete oil control yielding increased power, reduced oil temperatures and consistent oil supply and pressure. With most aluminum rods, pan will fit up to 4-1/2" stroke with modification. High oil capacity is required due to the high loads placed on the engine by a jet drive and the resulting engine killing high oil temperatures. Features a water-tight, screw-in dipstick which does not allow bilge water to enter the pan and contaminate the oil. Requires Milodon Oil Pump p/n 18760 Oil Pump Pickup p/n 18302.
