Does anyone know if the parts from a Wizard WD3 will work on a Mercury KE3? I found the WD3 in bad shape that I would like to use to rebuild the Merc KE3. I need a driveshaft,carb and prop. Does anyone have a parts diagram with part no's for the WD3? Also, I have read that there is a Wizard/Merc. comparison chart but can't find it.

I have torn down several of each. You can interchange these parts freely. Kiekhaefer's early K Model... design allows for easy exchange of good used parts from a donor motor to rehabilitate another.
Up to KE4/Mark7 WF4/WG4 the two brands differ only
in decal and paint color...although design evolved
so that motors made in same year most likely shared
while different years might have different parts.
If your KE3 tank is in poor shape you can substitute a tank from a KF5/Mark 5 as it looks much the same
and fits into the ring correctly. Due to weak lower
unit there are lots of KF5 motors cheap as
there are fewer by far usable lower units for them.
This suggestion is not meant to deceive but to get
you back on water until a good correct tank becomes
available. Works I have done it.
There is a chart of Mercury parts from K1 to KE3
that I have found useful...Wizards were probably
identical except for id tag,decal and postwar gold
instead of aluminum in color.
Keep track of fasteners,washers and where they go
Kiekhaefer used fasteners in nonstandard lengths
and sometimes different head sizes...If motor is
unmolested return fasteners and washers to locations
they were removed from...if some prior mechanic has
had his way the fasteners usually have battered
heads...beware of substitutions either of type of
fastener or location. Your parts motor is likely
only source of correct fasteners...modern fasteners
are different. Be aware that 1/4" fasteners come
in coarse 1/4 x 20 and fine 1/4 x 28 and Kiekhaefer
used both...a set of taps and dies and/or a thread
gage may be useful.

Thank you for the info. At this point all I need (that I know)for the KE3 is the driveshaft, carb and prop. The KE3 is apart so I'm sure there will be other things that I can scavage. The one thing that I really would like to find is a KE3 lower shroud. Where would I find the chart for the K1-3 parts? Great site.

Lower shrouds and other cosmetic parts tend to be hard to come by and expensive.
I would not let that slow up project If at some point in future shrouds come your way not a problem to install. I do not know how far apart
your KE3 or WD3 are but it it were mine I would look
over all parts and use the best...If like me you tear
down completely you need to learn how...not hard but
technique is required as well as a small investment
Powerhead has two seals and three bearings in crankcase and loose needle bearings on lower end of
rod and an expensive to replace bearing on top end.
You can duplicate old gaskets by using old gaskets
as pattern or matching opening.
If when done you wind up with a few unwanted parts
let me know OR if you come up short I have a few
extras.
Carburetor is Tillotson AJ 10 or AJ 10B for KE3
All propellers for singles and twins thru WG4 Wizard
and KE3 Mercury are same part number...even KE4/Mark7
use same prop bored out to 9/16"
Drive shafts are same part number for singles and twins thru WD3/WD4 Wizard and KE3 Mercury.
These are interesting motors to restore as just about
any bad part can be sourced from a parts motor or
East Coast Marine and other on line vendors.
Loose needle bearings and fasteners can be pesky things to find outside of a parts motor.
There are several followers of this site who know
these and other motors so several opinions and
viewpoints can be expected and worth considering.

The parts list I mentioned is "New Part's List for
Mercury Models manufactured 1939-1953" available
from East Coast Marine although I think you would
need some experience to get best use of it. Useful
to determine things like which models is the rotor
type water pump correct for and which used the
vane type impeller. Kiekhaefer evolved the K Models
so although prewar models are differnt than postwar models there is a carryover of many parts. Chart enables you to pick up where changeovers take place.
Down side is until you know what part looks like
part number may not help.

Tech Info attached to this site does have a model
comparison but not that helpful as KE3 not included
...KE3 is essentially a WD3/KD3 with the "Green Treatment" to blend in with the new KF5 and KE7
models that had the "Green Treatment"
...later KF3 is a early K Model powerhead using a KF5 lower unit...required a unique crankshaft to blend
things into one unit.

Jim,

Does your Wizard WD3 parts outboard have a cowling and sparkplug cover? If so, would you be willing to sell them and the attaching bolts? Thanks.

Steve

The motor came without either the plug cover or the lower shroud. Sorry.

How is your KE3 coming along? if possible pictures
please and thank you. If your plans call for a runner
it is best to start with the best available crankshaft and drive shaft. Be sure to grease splines of each. Gear case bushings also places to check
for excessive wear.
Do you expect to have excess left over parts?
Or need something? I do have some excess as well
as a rebuild single powerhead looking for lower unit....sort of like the Legend of Sleepy Hollow.

Jim,

Thanks for the quick reply.
