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 3/4" reinforced marine grade hose.
6. Connect the discharge from the pump uphill to the bottom inlet of the air conditioning unit's condenser coil
with 3/4" or 5/8” hose as required. Connect the discharge from the condenser coil to the overboard
discharge thru-hull fitting with 3/4" or 5/8” hose as required.
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 thread sealer 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.
