Installation
The seawater pump must be mounted so that it is always at least
300 mm below the water line.
The seawater pump may be mounted horizontally or vertically,
however the discharge must always be above the inlet (fig. 5,
page 5).
– A: Correct
Steady upward flow from inlet to unit (8), then downward to
outlet (9), hoses double clamped (10).
Thru-hull inlet (1), ball valve (2), hose and strainer (3) should be
sized no smaller than pump inlet.
– B: Incorrect
Hoses must not have kinks, loops or high spots where air can be
trapped.
– C: Incorrect
Pump (4) and strainer (3) must be below water line (7).
– D: Incorrect
Strainer (3) must be below pump (4) and below waterline (7).
Ensure the water is flowing freely from overboard discharge while the
pump is running.
The speed scoop intake must face forward and not be shared with any
other pump.
The speed scoop and the shut off valve must be tight and properly
sealed.
A seawater strainer (3) is mandatory between the shut off valve
(seacock) (1) and the pump (4) to protect the pump from any foreign
matter.
Ensure access to the filter of the strainer (3).
