Purchased as spares for my Sunseeker which I no longer have. This is a salt water pump used for the air conditioning system. Internally water cooled and designed for 24/7 use. I had 3 but did use one on the boat and frankly, I wish I had done it sooner as it was whisper quiet compared to the 20 years old one I had. 2 available with free post via DHL
