pump from any foreign matter. Failure to install a seawater strainer will void the pump warranty.
The seawater system should be installed with an upward incline from the speed scoop & seacock,
through the strainer, to the inlet of the pump, next to the inlet of the a/c unit's condenser coil. The
discharge from the a/c unit should run to the seawater outlet thru-hull fitting that should be located
where it can be visually inspected for water flow as close to the waterline to reduce noise. All hose
connections shall be secured using double/reversed stainless steel hose clamps. Use Teflon tape
on all threaded connections.
Summary of the seawater system installation:
(1). Install the speed scoop thru-hull inlet as close to the keel and as far below the water line as
possible, facing forward. Bed the scoop with a marine sealant designed for underwater use.
(2). Install a bronze, full flow seacock on the speed scoop thru-hull inlet.
(3). Install a seawater strainer below the level of the pump with access to filter.
(4). Mount the pump above the strainer and at least 1' (305mm) below the waterline.
(5). Connect the seacock and strainer with an uphill run of 5/8" reinforced marine grade hose.
(6). Connect the discharge from the pump uphill to the bottom inlet of the a/c unit's condenser
coil with 5/8" hose. Connect the discharge from the condenser coil to the overboard
discharge thru-hull fitting with 5/8" hose.
(7). Avoid loops, high spots or the use of 90° elbows with seawater hose (each 90° elbow is
equivalent to 2.5' (762mm) of hose and a 90° elbow on the pump outlet is equivalent to 20'
(6.1m) of hose).
(8). Double clamp all hose connections with stainless steel clamps, reversing the clamps.
(9). Use Teflon tape on all threaded connections.
(10). Connect all metallic parts in contact with seawater to the vessel's bonding system
including the speed scoop inlet, strainer, pump and the air conditioner. Failure to do so will
void warranty.
