Marine Competition Dry Sump Pans > Products

Offshore, Drag Boat, Inboard Class racing, Grand National Hydro, and/or any form of power boat racing has a common debility; engine speeds that have far surpassed the perfunctory capability of the wet sump oil system. STEF’S has combined the latest in proven horsepower producing design concepts with unparalleled scavenging and oil control to meet the challenge in marine competition engines.

STEF’S Marine Dry Sump pans feature fully extended kickouts, teflon coated uni-directional windage screen, proprietary marine directional baffling for unsurpassed oil control, and optimum pickup location for consistent scavaging.

Because boat racing is as much about endurance as it is speed, special consideration is given to material selection and welding technique. Each pan is 100% heli-arc welded inside and out to withstand 100’s of hours of crashing through 6 footers at top speed. Every pan is leak checked at final inspection to insure quality to our customers.

Each pan includes mounting hardware.
