Whale Gusher Galley Mk3 Service Kit
by Dan Cross, Ennui Went #159
The following are the steps I developed when installing service kits for my two Whale Gusher Galley Mk 3 foot pumps. These pumps have been manufactured since 1984, so I suspect they will be found on most all of our boats. The service kit is part number AK0553. It is widely available. I bought my kits on eBay. They looked like old stock, but the parts were fine. I have serviced two pumps, so I have limited experience. The following procedures worked for me. But, they may not all be correct (please mention any needed corrections) and certainly are not the sole way to accomplish this task.
I found a pump exploded view with names for most of the kit parts. I could not find a view which names each pump part. So, I made up some part names to help with my description. My inventions are listed below and shown in Figure 1:
See the Observations at end of this article to change pump from right to left hand or to change the valve intake position from bottom to top.
I was impressed by the quality and design of these pumps. I can see why they have remained unchanged for 30 years. The only damage I found looks to be related to anti-freeze. I found a pink “high water” line in the pump attached to the refrigerator box. I suspect the line was created by anti-freeze left in the pump each winter. The lower intake valves in this pump were deformed. I don’t know for certain, but suspect that the damage is from the anti-freeze. The pump still worked, but it seemed to take a lot of strokes to clear the refrigerator box.
Right to Left Hand. My pumps are right handed. The front and rear covers appear to be mirror images. I suspect the pump hand can be changed from right to left by simply swapping the front and rear covers.
Intake and Outflow. The intake on each of my pumps is at the bottom. It appears that the intakes can be changed from bottom to top by simply switching the positions of the intake and outflow valve assemblies.
