There is no reverse on these pumps. We have a fill pump and a drain pump. But I will say this, I have had many priming issues with the rear hard take pumps. I found one to be cracked (do to a freeze, maybe?) and one the motor just failed b/c water got into is some how. There are 6 of these pumps on our boats.
Spencer, I am waiting on getting my boat back and to stop working OT. I want to finish this month long project and test it, then ride it. I only bought these pumps as spares. I do a week long trip and I would hate for one to go out, as they seem to.
Just went to test out my new ballast system - got about 7/8" full and the pump gave out. Thanks for this reminder Dave - I have one on hand and am switching it out today.
PS: Wake looks awesome now - cant wait for the other 1/8 :-)
