It replaces Mercury Marine 26-161622 and ships as one oil seal, one O ring, three drain gaskets and a cotter pin in a 150 mm x 180 mm x 40 mm box at 21 g.\u003c\/p\u003e\n\n\u003cp\u003eThis is the sealing set for the small gearcase on the portable and mid range motors. The oil seal sits on the prop shaft, the O ring seals the carrier, the three gaskets go under the drain and fill screws, and the cotter pin locks the propeller nut.\u003c\/p\u003e\n\n\u003cp\u003eOn a small motor the gearcase holds very little oil, so a slow leak turns to milky oil within a few trips. By the time it is brown there is usually water sitting against the bearings, and the repair goes from a set of seals to a gearcase rebuild.\u003c\/p\u003e\n\n\u003cp\u003eFitment covers the Mercury and Mariner 9.9HP, 15HP and 20HP models. Mercury built the same gearcase under both badges, so the kit covers either. Check the model and serial number before ordering, because the larger 25HP and 30HP gearcases take different seals.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable
