A/C tripping breaker

Wasn't this all about the AC tripping the circuit breaker? What happened there?
Also most raw water pumps (the small ones like this would be) are magnetically coupled and do not have a single shaft through the motor.... The motor spins a magnet and that magnet spins another magnet on the impeller separated by the plastic pump housing.

So when we manually bypassed pump with hose water, the system did not trip the breaker and kept running and pushed water through all the way. When we try to manually push through pump, it does what it was doing before (starts, runs for a few mins, trips breaker). So we think it’s the sensor that’s tripping breaker
 
So you have narrowed it down to either a bad pump or blockage. If you open the strainer and open the valve is water flowing?

When we open strainer and sea cock, water is flowing. Can there be a blockage inside the pump? We have checks for a blockage in every other place.
 
Yes, need to know more info about your pump. I would probably just replace it as it is easier to just go buy one vs find parts for an old one quickly in Key West. I keep a spare on my boat for this exact reason. If it is rebuildable then order the parts and rebuild it and keep it as your spare. For now head over to West Marine and pick up a new one, install it and you will be back in cool air. Warm weather is back in South Florida Today, your pump picked the best days in 10 years to fail..LOL it has been cold since Xmas Eve for this place.
 
Don't know how electrically inclined you are …….but if you are I would check to see if the pump motor has an external start capacitor. Usually a oblong oval shaped cannister type thing mounted on the outside of the motor. Very simply the capacitor kicks the motor into high gear so to speak when it starts up. If the capacitor has failed the motor may still run at a low rpm, and hence not be turning fast enough to move the required amount of water. Does it appear that the motor is running at the rated rpm? There should be a tag on the motor that shows rated rpm.
 
Is it a matter of loosing prime to the pump? Try running the drive motors in gear at the dock turn on the AC unit. The water movement under the boat should prime the pump
 
Thanks to everyone for your help! We replaced the pump and the main A/C unit is working great. We are still having issues with the fwd unit but I’m guessing something got messed up when it wasn’t getting water. We are just going to leave it for now since it’s not a priority repair :)!

Glad to help and thank you for the follow up... Always to good to hear the outcome. Whats the forward unit doing?

Just blowing air —not cold (or hot when we switch to heat). Sounds like compressor not kicking on. I can hear a click periodically but never compressor. So we just have been keeping unit turned off.

Yea thats going to be a little bit more involved.
