A New Water Pump Seal Is Now Available {1361, 7555}
- Marine Engine:
- C32 MARINE (S/N: RXB1-UP; RNC1-UP)
The new water pump contains an improved O-ring seal that prevents oil leakage from the back side of the pump. The 4N-5837 Water Pump Gp is a direct replacement for the 102-0459 Water Pump Gp on the C32 Marine Engines that are listed above. The effective serial number for the new 4N-5837 Water Pump Gp that includes the 9X-7371 O-Ring Seal will be (S/N: RNC02913-UP) and (S/N: RXB03475-UP). The 4N-5837 Water Pump Gp and the 102-0459 Water Pump Gp are not serviceable.
If the 102-0459 Water Pump Gp is leaking oil from the O-ring on the back side of the pump then replace the 4S-5898 O-Ring Seal with the 9X-7371 O-Ring Seal. The affected serial numbers are (S/N: RNC1-2912) and (S/N: RXB1-3474).
