Re: Evinrude Speeditwin Water Pump Seal

There is a seal of sorts. Under the impeller, in the hole that the drive shaft goes into, there is a series of pieces that make up this seal. The first is a "grease seal retainer", part # 120827, which is essentially a soft metal washer. It is held in place by staking the aluminum around it.

Under that is a "Grease seal assembly" part # 194943, which is basically a rubber o-ring. Might be square cut, but I am not sure about that.

These sit on top of fibre drive shaft bushing. part # 170192.

Lots of pieces, but I think as long as it is fairly intact, the fact that you run grease in the lower should keep things OK for a while. I would just check periodically for water in the gearcase.

By the way, I got all this information from a SpeediFour parts list. I have a SpeediFour and a SpeediTwin that I recently went through, and the lowers are pretty much identical regarding these parts.

Good luck!
