- 1970 Egg Harbor 37 extended salon model
Mine may be low on refrigerant. I have a sight glass and can see some bubbles. I last added refrigerant about 5 years ago myself. Mine is a 16K BTU water cooled marine unit. Has split, so large evap in main cabin, and small evaporator in lower cabin.
I have been using during this heat wave. When it is 100 outside, inside temp I can get to mid 80's with a vent discharge air temp of 65*F
When the outside cools down into the upper 80's, the vent discharge temp can drop to 53*F. Boat will get to the 70's.
If the sun goes down, boat cools off well. But with the sun on full bore heat, boat does not cool well. My Bimini top is off the boat. Boat is a 37 foot Egg Harbor sedan cruiser with upper and lower cabin.
Yesterday, unit was drawing 13.3 amps.
Later, when sun went down, amp usage went to 12.5 amps.
I figure that is due to higher system pressure when it is real hot, causing the compressor to draw more amps.
