Re: 1967 Evinrude 60hp Sportfour lower unit
There's seals on every opening, the prop shaft, the drive shaft, the shift rod, the bearing retainer. You have to remove the water pump to get at the gear case seal on the drive shaft. These seals keep oil in and water out. Don't forget the drain and vent plug gaskets too. Often these are the source of leaks. Have you used the BRP site for exploded parts diagrams?
