1998 Wellcraft 3000 AC not cold 100% of time

[bjt0307]

I just purchased this boat a few months ago. The AC works great at times and other times it doesn't blow cold air. I noticed on other boats the water streaming out the side. My boat the water comes out but not with the force of other boats. I've read to make sure the sea cock is clean but I am not sure where that is. Any ideas on how to get cold air 100% of the time? Is there any maintenance that needs to be done?

Your AC unit is cooled by sea water. I would trace the lower connection on your AC unit through to your sea cock which should be towards the stern somewhere. You should also have a sea strainer that is most likely partially clogged before the water travels from that to pump which then travels through the AC unit to cool it. When does the unit not blow cool? if your pump fails like mine did you will have no water discharging and your ac unit should go into a trouble code of too high of pressure and turn off condensor. Then fan will run but it will no longer produce cool air.

The seacock on my 98 Martinique is righ in front of the starboard engine. Make sure it's closed before you unscrew the cap to pull out the basket and clean it.
