I have been battling against my new impeller for a 1975 7.5 hp Merc. Lining up the impeller sqeezing the fins lining up to the "greased" & loose impeller key can be challenging with big fingers .
So simple a job after a few utubes....
The drive shaft is off-set from center in the small impeller housing.
The trick is to orient and align the impeller key using the widest gap side between the shaft and the housing itselft.
insert & bend the fins CCw in the narrow side of the housing and the extended fins will bend and slide nicely in the wider side over the key !
...voilà... easy as pie.. no cursing to
