Product Details

✓- Direct replacement for Mercury Marine OEM 26-830749 and 26-930749. Cross-references with newer Mercury part numbers 26-8M0204694 and 8M0204693. Dimensions: 9mm / 0.35in ID, 14mm / 0.55in OD, 1.5mm / 0.06in thickness. 15-pack provides enough gaskets for multiple complete lower unit gear lube services — each service requires 2 gaskets (one for lower drain screw, one for upper vent screw).

✓- Used on lower unit gear case drain and fill screws on Mercury, Mercruiser, Mariner, and Quicksilver outboard motors and stern drives. Each lower unit has two drain points: the lower drain screw (for draining old gear oil) and the upper vent/fill screw (for venting during draining and refilling). Both use the same 26-830749 gasket.

✓- Stainless steel core with bonded rubber coating on both sides. Stainless steel will not rust or corrode in saltwater, freshwater, or any marine environment. The rubber sealing surface conforms to microscopic imperfections in the lower unit housing for a watertight seal even on older units with surface wear. Resistant to gear lube, saltwater, freshwater, and all marine fluids.

✓- Reusing old drain screw gaskets is one of the most common causes of water intrusion into the lower unit gear case — leading to water-fouled gear oil (the classic milky-coffee gear lube on the dipstick), gear damage, bearing failure, and eventually catastrophic lower unit failure costing thousands to repair. Replacing both gaskets at every gear lube service is cheap insurance.

✓- Compatible with Mercury Marine outboards 2hp through 400hp including Mercury 4-stroke, 2-stroke, Verado, OptiMax, Pro XS; Mercruiser stern drives Alpha One, Bravo One/Two/Three, R, MR, and MerCruiser inboards; Mariner outboards 2-300hp; Quicksilver outboards. Model years 1984-2024. Torque drain and vent screws to manufacturer specification (typically 3-4 ft-lbs / 4-5 Nm). Use Mercury 75W-90 gear lube.
