308626 OMC O-RING

OMC 0308626 is an elastomer o-ring seal positioned between the gearhousing and main engine housing on Johnson and Evinrude outboards. This seal prevents gear oil from leaking into the engine block and maintains proper lubrication of the lower unit. Widely available from Crowley Marine and eBay sellers as genuine OEM new old stock, replacement is straightforward during routine maintenance. The ring fits various vintage Johnson/Evinrude horsepower classes and model years.
