Through the Hull or Transom
On the engine the seawater cooling hose connects to a water pickup that is mounted through the
hull or transom of the boat. Refer to instructions provided by the seawater pickup manufacturer,
or Installation Manual supplied with product. A seacock (water inlet valve) is recommended.
A through the hull or through the transom seawater pickup, must have an internal cross sectional
area equal to or greater than seawater inlet hose to prevent restricting water flow. Pickup must be
located on the boat in an area that permits an uninterrupted flow of water to the pickup. Be sure to
make hose connections with double hose clamps.
Typical Through the Hull Pickup.
a - Through the Hull Pickup
b - Seacock
c - Through the Transom Pickup
d - Water Flow
IMPORTANT: Do not install water pickup directly in line with propeller, as pickup may
create turbulence and allow air to flow into the "propeller slip-stream." This will cause
propeller ventilation and will affect boat performance.
