unit, ensure that the mounting surface is a minimum thickness of 18mm (⁄") as shown in Fig. 4
• NOTE Do not screw directly to the hull - must be mounted on a bulkhead or on an additional board.

Please note that incorrect installation may invalidate the warranty.
The Gusher® 30 is designed for mounting on deck or through deck (BP3000), or on deck (BP3010) or through bulk-
head (BP3020).
N.B. The pump must be installed above the waterline.
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 servic-
ing.
Avoid installation locations which require a cockpit locker to be opened in order to operate the pump.
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.
To ensure good priming and flow, avoid sharp bends in pipework and fit a Whale strumbox /
strainer (Part number SB3422 / SB4222 / SB5865 (incorporating a non-return valve)) in order to
prevent the end of the hose sucking against a flat surface and therefore allowing the water level to be reduced to a
minimum.
7.A. For Mounting On Deck/Bulkhead:
1. Use pump as a template, mark off and drill four ¼” (6mm) holes. (Note. if replacing a Gusher® 25 the
mounting holes are the same).
2. Secure the pump with ⁄” (8mm) bolts.
3. Attach either 1½” (38mm) smooth bore reinforced hose with stainless steel worm drive hose clips. Ensure
tight connections. NOTE: Do not overtighten screws or hoseclips.
4. It is recommended that the outlet is mounted above the water line and anti-syphon loops are fitted where
applicable.
