That's a 1972 7.5 hp, made by Eska. It has a tecumseh air-cooled power head, with water cooling for the exhaust.
You can use a mix of 24:1, using chainsaw-type oil. You can view parts breakdowns at www3.sears.com, but enter your model number with a period instead of the hyphen.
Sears has some parts, but certifiedpartscorp.com has most parts for that outboard. You have to call them, with your model number and, preferably, the parts number from the Sears site.
