Reply To: Mercury KG-7 impellers/cartridge

[CHUCK]

John McIntosh has them listed on his site;  I don’t know if he actually has any.  47-21164 is what it shows in my parts listing.  Fits the KG-7, KF-7, and KG-4 .

I have read that an impeller for a KG-7, KF-7, KG-4, and some Wizards (Mercury 47-21164) can be made from a Sierra 18-3051 (OMC 395289).  You need to modify the height but that should be easy enough to do.  Verify this information;  it is in my notes.

Odd that OldMercs does not respond.
