The breakers under the rear bench are getting wet and going bad, has anyone come up with a way to keep the water out or at least off the breakers

Not to hijack your thread but, I have the same jumper setup in my Fountain. I always assumed that somebody added it. Sorry I can't help on your question.

you can buy the connector on amazon or ebay if you need the other side

My 38ZR has similar setup under the stbd rear seat (seat has to be lifted out to access) but the reset buttons have rubber covers over them. Where’s the water coming from?

drips down when someone sits down wet or i wash the boat
