LOCATION

Choose a position to mount the pump that is dry and away from standing water and is free from obstacles, where the
pump can be operated efficiently and comfortably. Ensure that the pump is installed to allow easy access for 
servicing.

Avoid installation locations which require a cockpit locker to be opened in order to operate the pump.

To ensure good priming and flow: 
• 

Avoid sharp bends in pipework. 

• 

Fit a Whale strumbox / strainer part number SB4222 / SB5865 
which prevents the end of the hose sucking against a flat 
surface and allows the water level to be reduced to a minimum. 

To minimise pumping effort, site the pump halfway (in height) 
between the strumbox / strainer and hull outlet. 

Mount in a position with the shortest run lengths possible.

• 

Use a reinforced hose on inlet to prevent collapsing during suction.

The Gusher® 10 is designed for mounting on deck / bulkhead (BP3708), or
through deck / bulkhead (BP3740). The handle can be fixed on four different
positions relative to the inlet and outlet (see Fig. 4).

To Reposition Handle:
(a) 

Slacken wormdrive clip and remove diaphragm

(b) 

Undo the bolts from bracket and rotate body to new position relative to the fork and diaphragm. 

Note:

Inlet 

and outlet are always at 180 degrees to each other

(c) 

Reassemble bolts, washers and securing brushes in bracket and tighten
