Whale Gusher®10 Mk3 Pump BP3708 / BP3740
INSTALLATION & USER INSTRUCTIONS
1

This bilge pump is designed to exhaust standing water only. Manufactured from durable diecast alloy to withstand
tough marine conditions.
This bilge pump is suitable as a primary bilge pump on boats equal to or greater than 12m (40ft). Output capacity
depends on installation, conditions during use and pumping rate. Users should be aware that capacity may not be
sufficient to cope with rapid influx of water. If it is intended for any other purpose or with any other liquid, it is the
users responsibility to ensure that the pump is suitable for the intended use and, in particular, that the materials are
fully compatible with the liquids to be used.
• The pump is designed to evacuate standing bilge water only. Bilge pump capacities may not be sufficient to
prevent flooding from rapid accumulation of water due to storms, rough weather and/ or rapid leaks created
by hull damage and or unsafe navigational conditions.
• Fitting an inlet strainer will ensure the maximum efficiency of the pump.
• This pump is not for use in systems evacuating water through a skin fitting or seacock below the waterline.
All pipework must contain a corectly installed anti-syphon valve/loop (next page see Fig 3 - Typical
installation diagram).
•Not suitable for pumping flammable liquids, diesel, chemicals etc. Suitable for bilge water only.
• With all applications, it is important that a system of safe working practice is applied to installation, use and
maintenance. Ensure the waste water system is drained before installation. In order to securely fasten the
unit, ensure that the mounting surface is a minimum thickness of 18mm (45/64") as shown in Fig. 4
•NOTE Do not screw directly to the hull - must be mounted on a bulkhead or on an additional board.

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

Fig. 2 Incorrect installation Fig 3 - Typical installation diagram

For Mounting On Deck/Bulkhead:
1. Use pump as a template, mark off and drill four 1/4” (6mm) holes.
2. Check flow direction and secure the pump with 1/4” (6mm) bolts.
3. Attach 1 1/2” (38mm) smooth bore reinforced hose with stainless steel worm drive hose
clips. Tighten to prevent air leaks.
4. With thru-hull discharge, make sure that the discharge point is above the maximum heeled
water line.
5. Check the installation for air leaks, correct priming and discharge.
For Mounting Underdeck or Thru Deck/Bulkhead
Two deckplates available - see accessories
1. Using template mark off the 6 holes for the mounting and cut out the hole for the pump handle. To preserve
the gaiter, ensure the top edge of this hole has no sharp edges.
2. Minimum deck thickness required is 1/4” (6mm). For thinner decks use a backing plate of suitable thickness
so that the backing plate plus the deck is at least the minimum thickness and no greater than 1” (25mm).
Bond the backing plate to the deck. If using Deck plate DP3804 the minimum deck thickness is ¹⁄ ” (13mm).
3. Position the pump under deck and check flow direction.
Work the rubber gaiter up through the hole until its flange rests on the deck. Secure the 6 1/4” (6mm)
countersunk mounting screws provided.
4. As points 3 - 5 of previous instructions.
OPERATION
The Gusher® 10 ensures efficient throughput with an easy pumping action. Full even strokes will obtain the best
results. The detachable handle is fitted with a lanyard and should be safely secured close to the pump.
Performance data is based on factory tests and is typical of what may reasonably be achieved. Actual performance
may vary depending on installation and operating conditions.

This Whale Gusher® 10 is designed to only require minimal maintenance.
WARNING: Before servicing pump, drain water from system.
Inspection:
The diaphragms and inlet valves are held in place by the groove in the pump body and cover. Following inspection,
ensure that they are seated properly in the grooves before tightening the covers in place. Regular inspection of the
pump is recommended. Access to the pump chamber is quick and easy, requiring no tools. Rubber components
should be replaced if worn or every three years regardless of condition.
During periodic shipboard inspections, the bilge pump should be visually inspected to confirm parts are in good
condition, especially rubber parts and mounting arrangements. The pump should be operated to show that it pumps
water efficiently.
Annual Checks
• Whale advise that the boat's plumbing system is checked annually for leaks and obstructions.
Optimal Performance
• Ensure this product is clear of debris
It is recommended a service kit is kept on board. These are available from your local chandlery.
Changing the Diaphragm and Valves
1. Slacken and remove the wormdrive clip to release the diaphragm.
2. Release diaphragm nut and remove diaphragm plates and diaphragm.
3. Replace old inlet and outlet valves. Note: both inlet and outlet valves are same shape. The service kits
contain two sets of valves - round ones for the MK 2 pump and square valves for the MK 3 pump. DO NOT
mix the valve types!
4. Replace diaphragm and tighten wormclip in position and test for correct priming and discharge.
