I used to see that a lot on Johnson/Evinrude power trim pumps. Which
were externally mounted and prone to water logging. People would park
their boat for the winter then wonder why the trim motor wouldn't work
the next year, and regardless on how you tried to clean them out,
those old prestolite motors were nye-on to worthless by then. Nothing
that money couldn't cure.

I did manage to fix this one. And that was 3 years ago and it's still
running so my fix "took". But generally you're right, these small
electrical motors get and stay wet for any length of time and they are
usually scrap. I wanted bennett to just sell me the motor since the
hydralic part was fine. They only sell the entire pump as a
replacement and it was almost $400. That was enough incentive for me
to spend a little more time fixing the motor. Puttting the pump half
back on it was another chore as it did not have any guide pins and
would bind easily if it was not in exactly the right spot. I ended up
attaching it just slightly snug, running the motor and then tightening
the bolts the rest of the way. I think the poor pump to motor
attachment was why they didn't sell either half individually.

I also had the joystick style control wear out on me. The current
slowly softened the plastic around the contacts until they sank too
far to work. I replaced it with an ordinary dpdt spring return
toggle. I don't use the side to side adjustment so having both tabs
go up and down together was not an issue for me.

Mind you I've had these tabs for about 15 years now so I can't really
complain.
