This is the first time i have worked on an old motor with one of these type water pumps in it. I do not know how much clearance should be between the cam and the rubber rotor.

Please look at this picture if you know anything about them and tell me if this is worn or OK as is.

Thanks,
Robin

Looks like it has a crack in it. I'd replace it.

Yep, that wobbler looks well used. Get a new one. Sea -Way Marine sells them.
