Circulating pump is leaking and appears the seal has failed on the shaft. Has anyone replaced this seal or is there a replacement pump available at a reasonable price. If so where would one be available for purchase. The existing pump is made by Johnson Pump. Thanks. Grant.
 
Ditto Sure Marine as a resource. I have an Espar hydronic, and they convinced me on the merits of changing to an AC circulating pump. Very quiet, long service life and low amp draw, although I can't quote you what that is. I've had it in for 5 years, trouble free.
 
I agree, Sure Marine will have what you need. Fixed mine.
 
Or call someone in Sidney who are Webasto dealers. Such as Vector, Raven or Philbrooks.
 
There are different pumps, but if you have an MP Pump 29924....

....then you need seal kit 28984. It comes with a shaft seal and o-ring. You'll need a small gear puller (for the limited use, I got mine at Harbor Freight). Its an easy job, 30 min max, to replace the shaft seal.
