This is a new to me boat and I am learing lots. First order of business has been to clean and clean and then clean some more. The boats water
pump has worked well until today.
The pump model goes on to say 12volt, 5 amp, 2.8 gpm. It also lists the initials ITT and the name Jabsco
So the pump suddenly began to run with no water
coming out of the faucets.
Inspecting it I see a motor
turned shaft that has what basically looks like the arm of a piston that is part of what appears to be a rubber diaphram on the top side of the pump housing/body.
shaft has a set screw that I think would or should set against the flat side of the motor arm thereby securing the "piston" arm to the shaft that would accuate the diaphram and deliver water to the faucets.
When I turn on the switch- the motor continues to run but the diaphram arm does not accuate and no water is delivered.
Any thoughts as to what is going on? The set screw was tight on inspection
. I have since loosened it and am wondering if it somehow became no longer "set" to the flat side of the motor shaft. In my limited time I had I really could not find the flat spot to try and reset the screw. I have not removed the pump as I was out of time. This may be the best approach and when removed I should be able to set the screw and also service
the pump if needed. My concern is - could there be more trouble inside the diaphram ?
Any advice is certainly welcome.
