Maintaining Dripless Shaft Seals

Dripless shaft seals don’t have valves to turn the water off Propeller Shaft-Seal Procrastination

Don’t fear dripless shaft seals.

Since dripless shaft seals don’t have valves to turn the water off, some boaters seem afraid to work on them, instead hoping they’ll just keep working. The truth is dripless seals—either lip-seal or face-seal types—require just a little simple maintenance once or twice a year. Most of it can even be done with the boat in the water. But if you ignore those seals they can turn ugly.
