Re: 1948 Champion Blue Ribbon 2K Lower Unit Seals

[David Stanton]

Another way to put grease in the lower unit on that model is to remove the few screws that hold the part directly behind the prop to the lower unit – then pack grease in with a putty knife. Lubriplate 105 like the others said, or sometimes I use lithium, water-resistant wheel bearing grease for boat trailers.

The putty knife method I learned from Lyle Swanson – Champion factory employee who got the factory parts and ran a parts and repair shop until the mid-1980s. You may need to make a new gasket for that part, but that’s easy.
