Engine Water Pump (Jun 2005))


Replaced the original Oberdorfer pump with a new one in March 1991.  This was the old style pump with a grease cup that required  turning the cap a quarter turn each time that we set sail. Shaft and seals of this "new" pump were replaced in June 2001.


In 2005, Moyer Marine introduced an improved water pump (Model MMI 502) which did not
require a grease fitting for lubrication. This new pump, installed on 25 May 2005, mounts in the same location as the original. There is no grease cup and the rear cover is easily removed by rotating thumb screws. Cover removal allows easy access to the impeller and drains the pump for winter storage.
Sorry to say, this pump (#1), began to leak engine oil from the seal area on 12 Jun 2005. We put the old pump in its place and contacted Moyer Marine and they provided a replacement (#2) which was installed on 17 Jun 2005. This second, new, pump, which, according to Moyer, had a secondary oil seal, began to leak engine oil, in the same place, early in April, 2006. We again contacted Moyer Marine. They shipped us pump #3 which was installed around 22 Apr 2006. This pump #3 has performed well and the new features make it a pleasure to own. Moyer asked that pump #2 be returned to them so that they could do an investigation. This was done and they provided a report which stated that pump #2 was, mistakenly, the same version as Pump #1. We seemed to have helped Moyer Marine Inc. to overcome the teething problems with this new pump.


{Lesson learned:
Always take the time, cost and effort involved to keep the water pump operating well. The engine is totally dependent on it's operation.}
