AC Pump doesn't move water

[Doc O Rock]

My 1999 380 went in the water Monday and yesterday I stopped by the boat to check on her because of the wind. She was sitting snug and pretty on he lines. I started the AC because of the heat, and I heard the pump and AC come on, but no water. What should I check? Do I need to prime the pump, or is the impeller gone?

IF its been out of water I would prime the pump. Those are mag pumps with a ceramic impeller.

Make sure no-one closed the seacock. IMO, the easiest way to prime the system is to start your genny and go for a ride. Once on-plane, have someone kick on the system. (the through-hull has a slight scoop to it)

Method two isn't as fun: have someone block one of the discharge through-hulls while you use a hose to backflush water into the other. If you have any quick-connect hose fittings, the male quick-connect is a good fit.

Method #3 - Pull the outlet hose off of the pump outlet for a few seconds with the seacock open. Reinstall after water comes out of the pump.

Turn system on and go to the pump in the ER and check to see if it is running... I replaced mine a couple of years ago, it was dead.

That's the way I've been doing it for years now. Simple and quick.

I'm going to install a T in that hose with a valve on it so I can just open the valve to prime the pump. I'm in dry stack so it needs to be primed every time they put me in unless I close the seacock before they​ pull me out. I don't have a genny, so my AC only works at the dock on shore power. Taking a quick ride always works, too.

I like your idea, but to also be able to had a garden hose to the system . Up in Lake Erie the algae gets so bad that the pick up get clogged sitting at the marinas, and it would be nice to be able to hook up a hose and by-pass the raw water. I was able to get the pump started.

Just a heads up that it's frowned upon at most marinas to run the A/C off of dock water.

I know the owners of my marina would go ballistic if I did that. You can fill half of a swimming pool overnight with a garden hose. Can you imagine their water bill after a week of running your AC off of their hose. $$$$

Shop vac on output with seacock open. Reverse procedure for winterization to blow out the strainer and seacock.
