Re: sears outboard 5hp help
Hi,
That's a 1971 5 hp model, made by Eska. It's air-cooled, with a water-cooled exhaust. Fuel:Oil ratio is 24:1, using the type of oil used in chainsaws and other air-cooled two-stroke engines.
You can look up parts diagrams at www3.sears.com. Plug in your model number, using a period instead of the dash. Sears has some common parts for that motor.
For other parts, contact certifiedpartscorp.com. They bought the entire stock of parts from Eska and continue to buy parts from other sources. You'll have to call them, but they're very helpful.
