Sterndrive Engineering (SEI) is one of the largest providers of marine supplies in the United States for stern drives and related products. SEI’s marine supplies are sold to both dealers and do-it-yourselfers throughout the United States, Europe, Latin America, Australia, and the Far East. It is very easy to become a marine supply SEI dealer. Simply fill out the online dealer application and fax it back to SEI at 727 461 0779. To be a dealer, you must be in the marine business and provide proof in the form of advertising, yellow page listing, or other documentation.

SEI’s marine supply products for stern drives include complete stern drives; stern drive parts such as cases, gears, and shafts; gimble repair kits; hydraulic parts including trim cylinders and pumps, and other marine equipment and supplies. At this time, most of SEI’s marine supplies are products that fit and/or replace parts for MerCruiser’s® Alpha One® and Gen II stern drives. SEI’s catalog of discount marine supplies is online in shopping cart format. SEI is very much focused on stern drive-type products and does not offer general marine equipment and supplies.

At SEI, our greatest asset is our people. Our sales staff is well trained and eager to help you find the marine supplies for your stern drive that you need. SEI also offers technical support both on the phone and through its forum at Sterndrive.cc. Many dealers and do-it-yourselfers rely on SEI to answer hard questions when troubleshooting MerCruiser’s® Alpha One® and Gen II stern drives.

At SEI, we make it easy for you to order. Whether you want your order delivered directly to your home or marina, we will always do our best to accommodate your needs. We are boaters also, so we know that boating enthusiasts are happiest on the water. Our goal is to make it as easy as possible for you to find all your boating supplies in one place.

Thank you for your interest in SEI marine equipment and supplies.
