Air conditioner on 2900 scr maximum 2003 boat

Our problem is with the air conditioner blowing warm ish air, we have plugged into shore power with 2 prong electoral cord- the temperature keeps reading 82 and above - the thermometer on the wall that has the low cold symbol shows 65 and we can't change it- any suggestions on how to turn on the air conditioner properly and any suggestions what could be the problem of blowing cold air out is helpful thank you

Is the seacock open for the AC? Is the raw water flowing through the AC? If not the system cannot cool.

Check to make sure there is water coming out of the hill at the bow (don’t stop at checking the valve). On my 2900 the pump would get air locked on haulout and wouldn’t pump water when it was splashed. The fix is easy if that’s your problem … open the seacock and break a hose connection after the pump until water flows out to ensure the pump is primed with water. Reassemble and fire up.
