How to check the impeller of the raw water pump
1. Ensure that the seacock is closed.
2. Release the six setscrews (A1 page 17) which fasten the end plate of the raw water pump and remove
the plate. When the end plate of the raw water pump is removed, some raw water will flow from the
pump.
3. Remove the rubber end cap (A1) and then pull the impeller from the shaft.
4. Clean the contact surfaces of the pump body and the end plate.
5. Inspect the rubber impeller for excessive wear or for damage and renew it, if necessary. If pieces have
broken off the impeller blades, check the strainer for the raw water pump, see page 18.
6. Apply Spheerol SX2 grease or liquid soap to the blades of the impeller and fit the impeller into the
housing with the blades bent counter-clockwise (A). Fit the rubber end cap.
7. Apply jointing compound to a new joint and fit it to the body with the wide area of the joint over the
eccentric plate in the body. Fit the end plate and tighten the end plate screws.
8. Open the seacock.
