OUR MISSION STATEMENT

SEI's mission is to make owning, operationg and maintaining a stern drive more affordable.

Only new at SEI

Simply put, buying a remanufactured drive is risky.

Common practices in the industry include reusing critical wear parts such as cases, gears, shafts and bearings. Inspecting these parts to determine a reasonable expected remaining life is nearly impossible. Consequently, premature failures are common.

Why risk relying on used and possibly worn out parts when you can buy brand new drive a from SEI for less money?
Tested, Tested & Tested Again

Sterndrive Engineering consistently conducts product testing at our private research lake located in Central Florida. This rigorous testing ensures the reliability and effectiveness of our products, giving us complete confidence in their performance.

Combined with our comprehensive 3-year warranty, it's evident why SEI is rapidly emerging as the leading provider of replacement drives globally.
3 Year Fault Free Warranty
