My gen was working fine a weeks or so ago. I pulled boat out of the water for maintenance and it was out for 4 days. Yesterday we went back in water and I ran the gen but no water came out of exhaust. I checked seacock and it was open. I also have a T connection where I connect water hose for flushing.
I also tried using the water hose with water being forced into the gen, still no water in exhaust. Any ideas where I can check?

Just from reading stuff on here, when was the last time you changed the generator seawater pump (impeller)?

You most likely lost the prime. It drained itself when you pulled it out, through the thru hull fitting
Two ways to fix this. Take it for a ride and it should self prime the system or when your setting at the dock crack the lid on the sea strainer to let the air out

I was thinking he tried to prime the gen by doing this^^^^^

Sounds like an impeller or this sleeve (see link below) that couples the rotor to the shaft of the pump might have split resulting in no raw water flow. Easy and cheap fix.
