Am I being too lazy? I should change the lube in my 200 Johnson OB, but it's in the marina and I don't want to haul it out just for that. I see there are a number of pumps available in the various marine catalogs, most of which seem designed for oil changes in 4-strokes. Any one had experience with these for gear lube? I'm not interested in polluting, so should I just bite the bullet and haul it out?
