    Mine looked a lot like that and I just had to replace it. Biggest concern is water getting into the reservoir. Might just run a bead of silicone around the motor where it meets the reservoir as a precaution.

    Mine looked like that too. It is not what the outside looks like it is what the insde looks like. I just replaced it and put the old one in my parts cabinet, because it still worked fine. The motor was like $113 from CPW. I also agree with running the bead of silicone around the base in the little groove. Kind of a weird design. No gasket or o ring to protect it from water coming in.

    Take the wires off, be sure to hold the nuts behind the eyelet too. Take the 2 bolts on top of the motor out and you can remove the motor. You may have to tap it with a rubber hammer. There is no "bottom" on the motor so if you pull up on the housing the armature stays in the pump. If it does it just slips out. Sometimes you can get them both off at once if you have "3 hands". Same way to put it back on. The hardest thing about it is getting the armature back in the housing trying to hold the brushes in. Took me 1 hour tops and that included doing a bunch of other little things like touching up the paint, dielectric grease on all the connections and a simple drain and fill.

    No need to worry about it rusting through it's pretty thick stuff. I would say 1/4 inch. A little wire brush and paint will go a long way. You can disassemble and clean it. That is pretty much free.
