A great many thanks to Lincoln Davis III of the PineTree Boating Club for helping to identify this motor block!!! 😎

I am going to post an excellent article by Tom Thuerwachter showing some pictures of complete motor.
Tom states in his article from Jan 2007 AO that "It has an odd intake manifold, more like a car rather than an outboard.
It has reed plates on the block.

OK Louis you got that motor all figured out. Now slap some wizard parts on there so we can hear that baby run! Don’t you say something like 10% knowledge and 90% perspiration!

The sticky point is the missing intake/reed assembly. Finding that unique part for a one year limited production semi prototype model strikes me as a toughie. If anyone has an extra
intake /reed assembly I would like to hear from them.

Are Mercury K5 and Wizard WA6 related 1940 models?
I believe they are. Some sources state Kiekhaefer Wizards began with 1941 models
My current belief is that Mercury K and Wizard WA are 1940 models
and Mercury KB and Wizard WB were 1941 models

(My best guess is that Mercury made final runs of KB3 and KB4
up until end of nonessential civilian production halt in February 1942
without changing to a KC prefix.)

Update on recreating Mercury K4…powerhead is assembled, leg is being put together, in a day
or so parts will be joined. Getting K4 this far depended upon a lot of help from a lot of friends.
Thank You one and all.
A more complete story later.

The story of the unknown crankcase assembly is now known. A few newly found remnants have shown up, including the rope plate marked Mercury K4 serial # 1150 and the Eisemann fly wheel magneto assembly which has a small diameter mounting hole. I was concerned that the crankcase extension might have been machined undersize at some point as the magneto plates on hand had large diameter mounting holes and did not fit the crankcase snugly. All in all the bare crankcase assembly has led to a very interesting project, although, not without some learning experiences. Not a complete ready to show and go motor as a few more hours of detail
work remain.
I know of 6 examples of Mercury K4. I wonder if there are others in club with them and I am also curious as to Mercury K5 model and Wizard WA6 versions. At some point I will write up a long story with all the twists and turns complete with photos and credit due to those who contributed to project. I owe them one and all.

Louis, Call Walter Chute in Niagara Fall NY. He is very knowledgeable on Pre-War Kiekhaefer motors.
