Michigan Wheel 3 blade aluminum propeller ID

[green-thumbs]

Incomplete letter group "M" followed by B? and number 23
It is for a Mercury as it accepts the metal discs and rubber element clutch
Appears to be for 9/16" prop shaft.
Michigan Wheel catalog no help
Old Iron site for Michigan Wheel may have it but I did nos see it.
The propeller may be for a Mercury KE7 , however it is larger than the general purpose
3 blade K40…which would bog down a high rpm Mercury.
Thanks

The disk type was used on KF7 & KG7 with 5/8 " shaft, KE7 was 9/16 and used shear pin.

Both propellers are adapted to use the rubber element type clutch 52-22475 as used with the KE4/Mark 7 and are for 9/16" prop shaft. The identity of prop, specs and intended purpose would be nice to know. Diameter and area of blades seem more ‘barge pusher" than K40
Mercury parts manual shows only shear pin with KE7. Since the propeller shaft is same,
KE7 could be set up for shear pin or clutch.

KF7,KG7 and KG4 are based on larger 5/8" prop shaft so they are not in this picture.

Simple question is What Michigan Wheel Propeller do I have….given the particulars it
has to be for a KE7 Mercury..
Thanks
