Mercury Marine 8M0166756 Bearing Kit Genuine OEM product	$37.59~~$46.99~~ In stock Only 2 remaining	Best	OEM Mercury kit using Koyo Japan components (markings show 'KOYO HI‑CAP L44610' on the cup and 'L44643 R' on the cone). This is the common L44643/L44610 trade size (also called Set 14): 1.000 in shaft bore, 1.980 in cup OD. Tapered‑roller bearings are two‑piece (cone + cup) that carry both radial and thrust loads; correct preload during assembly keeps gear mesh stable and minimizes vibration. The HI‑CAP/Koyo Japan marking indicates tight tolerances and high load capacity, and the kit is specified for many Mercury/Mariner gearcases, making it a true drop‑in. For longevity and precise fit in marine gearcases, this OEM kit is the safest choice.

GLM Marine 21585 Tapered Roller Bearing - GLM Products (21585) (viewing this product) Aftermarket product	$29.09~~$36.36~~ In stock Only 1 remaining	Good	Aftermarket GLM set marked 'CHINA L44610 PEER' on the race and 'L44643' on the cone; PEER is an established brand owned by a major bearing group. The included paper separating cone and cup helps prevent shipping scuffs (nice touch visible in the photo). This is the same L44643/L44610 trade size (Set 14) used by the OEM, so it installs like‑for‑like. As with any tapered‑roller set, always install the matched cone+cup together and set preload per the service manual; avoid mixing with the larger L44649 cone (1.063 in) that also fits an L44610 cup. User reports on GLM parts are mixed overall, but this bearing is a serviceable, budget‑friendly option when OEM isn’t required.
