OldMercs.com over the last month just discontinued their impellers for the WG4 and older Wizards and Mercs utilizing this style of lower unit:

Hold onto your cores. You have two choices for a new impeller. the mercury Part number is 47-24447.
1. Impellers by Brian (Brian Wilcox)

2. The flying Scott guy:

I have one of the last from East Coast Marine and will report back on the Impellers sold by Brian. Others swear by them, so I hope they fit and work well.
Happy Motoring. GreenThumbs aka Louis has also used Brian's impellers so they should be fine.
Types of water pumps used on Mercurys KE3 and prior and the Wizard WG4 and prior...
there are two types of water pumps:
1) Oscillator part# 24427
2) Impeller part# 47-24447
The New Parts List for Mercury Models 1939-1953 offers contradictory information as to which models
used which...suffice it to say prewar likely to have
oscillator and postwar mostly Impeller.
I have yet to find an impeller type waterpump in a
prewar Kiekhaefer or an oscillator type waterpump in
a postwar model although the 1946 KB4 may be
the exception that proves the rule.
Note: The Oscillator and Impeller type water pumps
will interchange "as a unit" AND Kiekhaefer
offered a factory Kit part# 46-24424-A4 to
upgrade to the impeller type.
So far as I know the Oscillator part# 24427 has not been offered by East Coast Marine. Until recently the impeller part# 47-24447 has been available from East Coast Marine.
Sierra: part# 47-24447 clicks but comes up NLA with a
crossed out price of $3.00!!!
Brian Wilcox has been making up impellers and
oscillators (for several models and brands of outboards) for several years on more than a hobby
and less than a business basis. He also makes
up recoil handles, handle grips and the cushion pieces
that fit between tank mounts and powerhead.
Ours is a very small hobby and if it were not for
mini suppliers like Brian, restoring and using
an old outboard motor would be difficult if not
impossible.
