Having my pump apart for some other detailing I noticed my new 13/18 Solas has a gap between pump hub and impeller hub of .135" Seemed a bit much compared to some of my other boats, and the trailing edge of the impeller is .400 from the outer edge of the pump. Is what others have seen with the 13/18?

Of course I also observed one trailing edge a bit less than the others, had forgotten to always check even a new impeller.
