Removing the pump

Removing the Bilge Pump

The following sequence should be followed:

• Remove the teak centreplate capping by unscrewing the 8 self tapping screws holding it in position. This gives access to a square inspection hole cut into the aft end of the GRP casing.
• Loosen the Jubilee hose clip which holds the polythene tube on the (top) outlet pipe of the pump and ease the hose off the outlet pipe.
• Undo and remove the nuts and bolts/screws securing the pump to the mounting board
• Remove the four large dome-headed wood screws securing the plywood mounting board, two on each side of the centreplate casing.
• Twist the mounting board sideways and push back so that there is more room to twist the pump unit.
• Once the above has been done it should be possible to twist the pump unit sideways so that it can be removed together with the attached inlet pipe which extends down into the bilge.
• It should then be possible to twist and remove the plywood mounting board in the same way.
• Finally the polythene outlet pipe can be pulled out of the vent in the top of the centreplate case and removed.

The aft end of the centreplate casing with the teak capping and bilge pump removed This photograph of the rear end of the centreplate casing, shows the inspection hole cut into the aft end of the top of the GRP casing, the hole which takes the outlet hose from the pump into the back of the centreplate casing, and the cut out area on the aft end of the casing where the pump is mounted. Note that a thick 'tongue' of GRP follows the slope of the underlying inner shell of the centreplate case. A rectangle has been cut into the front of this 'tongue' to accommodate the pump inlet pipe. Compare this photograph with the sketch section at the top of the page. (Click on image for larger view)

The mounting board and accessories after removal Photograph of the damaged and split plywood mounting board and rusted jubilee clip. Note the severe kink near the top of the polythene outlet hose (on the right). This constricts the flow of water and reduces the efficency of the pump. The four dome-headed silicon bronze wood screws pass through the GRP sides of the centrecase and are used to hold the mounting board in position within the casing. (Click on image for larger view)
