Sears Outboard 3 1/2 hp 3.5 Spark plug info

[volks_r_us]

Hello,

I am working on an old Sears engine. it a 3.5HP air cooled. I am not sure if the engine is an Eska or a Mc culluch or even Elgin.
I can figure out which spark plug goes there. I came with not plug so I have no reference. I am pretty sure it must be a champion, Maybe a J6C but I don't know for sure.
Can anybody help find out what goes there I would really appreciate. it the only thing I am missing the try this "bad boy" out

Model No. C574,60007
Serial number: 82250****
Made in Canada

Thanks Guys

According to link below the 574 is the Elgin (Ted Williams) model made between 1959 and 69 by McCulloch.

They also have manuals for these motors for $12 to $15 or so

Reasonably sure it is a Champion H-10-J (now H-10-C?)
