Johnson Evinrude Outboard Gearcase Seal Kits

Gearcase Seal Kit

Gearcase Seal Kits

Sealing the gear oil inside the gearcase, and keeping water from intruding into the gearcase are the two aims of all the shaft seals, o-rings, spaghetti seals and gaskets in a lower unit. When you check your gear oil as a part of regular inspection, if you find the oil to be milky, it means water has been introduced somewhere. A seal kit and fresh gear oil will put you back in the safe zone.
