I may have to rethink the cosmic ray theory of mine. I went sailing this weekend and, just as I was about to enter the planned anchorage (in Worton Creek, for the Chesapeake cognoscenti), the temperature alarm came on! I anchored right where I was, in the approach to the Creek, and ended up staying there the whole night.
So what caused the problem? I am pretty sure now that the water pump is leaking from the weeping hole: when I feel there, it is definitely moist. Rather than blaming a cosmic ray, my new theory is that this caused a slow leak which was hidden by my habit of keeping a diaper under the motor.
I should probably be prepared for this to happen. I have NEVER been able to get the impeller off its axle without the axle coming out. I understand that this is not good for the seals, right?
I have an Oberdorfer pump and I understand there is a rebuild kit for $153.- (

https://moyermarine.com/product/mmi-...p-csob_00_365/). I am reasonably handy (I think) but I am not a mechanic and pressing bearings or seals on axles is not something I am familiar with at all. So I am tempted to go whole-hog and get the new pump (it is 100% compatible, right?).
Good decision? What say ye?
