Lower Unit Seal Kit 396349 18-2660 for Johnson Evinrude 50 60 65 70 75 HP
Product Overview
Gearcase lower unit seal kit for Johnson and Evinrude outboards from 50 HP to 75 HP, supplied as 1 x complete seal kit. It replaces Johnson Evinrude 396349, 0396349, 5000309, 324937 and 314082, plus Sierra 18-2660 and 18-8383, SEI 95-366-11K, OBR JE-934, Mallory 9-74103 and GLM 87601. The kit reseals the gearcase so gear oil stays in and water stays out; a failed seal shows up as milky gear oil, an oil slick under the leg, or water found when the drain plug is pulled.
