If it is really a Yamaha get a Yamaha manual.

If the "Chinese Yamaha" is some salesman's claim about a knockoff I have no suggestions.

Re: ospray outboard (chinese yamaha )

It would be helpful if you posted the correct name of your outboard. You have an OSPREY outboard not an Ospray. That motor is fully parts compatible with the equivalent Yamaha motor. Did you check the spark plugs? They should be BR6HS. If you have pinging the spark plugs shoud be replaced. Pinging is often caused by a lean fuel condition. I would look to debris in the carburetor. Are both spark plugs firing? What country are you in? Are you using gas of the correct octane?
