In case anyone wants to follow along with the seal replacement process, I’m running a thread here:
https://www.sbmar.com/community/topic/leaking-smx-pump/
So my mechanic informed me this week that the pumps from SBMAR are the same pumps as what are on the engines, except for the custom pump shaft. That different shaft has a different keying, and so they use the different (custom SBMAR) impellers. But other than the shaft and the impeller, the pump is exactly the same as the normal pumps. If this is true, it makes switching to the SBMAR pumps a lot less attractive, for it would be the same pump but only one source for impellers. Can anyone confirm or refute that these pumps are the same?
