Diesel Spares Kit M Series
(Late Sherwood Pump, B-Series Engines)

Part #: Z4786
This kit contains essential parts for routine maintenance of your Universal Diesel "B" series engine that uses the later style Sherwood water pump. The kit includes two oil filters and two fuel filters (one of each for now and another for a spare), and a new impeller, gasket, and O ring for your water pump. The only thing you need to supply is the oil.
The difference between each of the Diesel Engine Spares Kits is the parts included for the water pump and the lube oil filter (The 5411 uses a different oil filter). To identify which water pump you have, refer to the additional picture below. This kit is for the later B Series engines that do not have the cylindrical remote fuel pump, so the fuel pump filter and gasket included in the other spares kit are are not included.

Applicatioins include these engines (and the boats that we are aware used these engines... There could be other combinations as well):
• M-25XPB (Catalina 28 MkII, Catalina 30 MkIII, Catalina 310)
• M-35B (Catalina 34 MkII, Catalina 350, Catalina 36 MkII)
Some owners report that their boat with the "B" series engines does have the remote cylindrical electric fuel pump. If that is the case aboard your boat, order #Z2555 below which does include the fuel pump filter and gasket.
