Sometimes, when you think you've learned it... M/W Sea king 7.5 ID help needed

[jim j geezer]

In another thread I learned that M/W would reverse the first two digits of the SN to 'hide' the year of manufacture. Apparently that holds true for only certain manufacturers.

Just picked this up today: Advertised as "70's" <--I think not!
Model: K750 3107D
SN: 996009
Type: XTV52207

To my eye it looks like a Clinton air-cooled powerhead - based on the rewind assy. I think Clinton preceded Chrysler in supplying M/W. 3-blade prop and F/N shift. A note taped inside the top cover says the fuel mix should be 40:1.

Any & all info welcome.

K750 appeared in 74/75.My after market manual indicates 48:1 for the 7.5.
