We spent a long weekend at the boat recently and realized that the air conditioning was not working properly. Scott proceeded to check out the wiring and found out the the water pump that pumps in sea water to cool the unit was not working. Luckily the previous owner had bought one and never installed it. So, after much sweat and a few tense moments wondering if the seacocks were really closed or not it was time to test the unit. It works beautifully now and this past weekend we spent at the boat we stayed inside through the hottest part of the day and it was wonderful.
