Mercury Marine 43035A4
Gear Housing Seal Kit
Gearcase sealing is labor-intensive and seal failure can allow water intrusion that risks major internal damage, so maximizing reliability matters more than small parts differences. The OEM kit’s identifiable premium suppliers (NOK seals and Interface Performance Materials gasket with a controlled silicone bead) provide the highest confidence in fit, material compatibility, and long-term sealing.

Includes a coated metal-cased seal and a Mercury-embossed molded rubber component, indicating OEM-spec materials and tooling for critical gearcase sealing.

Higher-quality aftermarket kit with multiple seals clearly stamped "USA" plus a branded NAK rubber-coated seal, and gaskets that use a formed red silicone bead to improve sealing. It still differs from OEM sourcing (no Interface TS-9006 gasket and no NOK-marked seals), but the identifiable seal markings suggest better-controlled component quality than typical generic kits.
