SEAWATER SETUP
Seawater System
All Mabru marine air conditioners are
water-cooled and require a seawater intake system. This system is comprised of a speed scoop, intake thru-hull fitting, seacock, sea strainer, and water pump. These components must be installed at least one foot below the boat’s waterline to ensure proper water intake for cooling and efficient operation.
The speed scoop should be facing the bow or front of the boat and as far underwater as possible. The speed scoop must remain underwater in all conditions. If air gets into the seawater inlet, the pump will stop pumping water. A bleeding valve can be used to clear the air from the pump.
Water inlets should not be shared with galleys, heads, or any other pumps. Each air
conditioner should have its own thru-hull. The intake cannot be mounted aft of hull steps or any other hull obstruction that will affect the water flow to the intake. Components such as transducers, other intakes, or strikes can cause cavitation in the water flowing to the intake which will introduce air into the air conditioner’s sea water intake and possibly cause airlocks.
Above is a proper example of a pump installation with our ½” bleeding valve on the outlet of the pump.
