I have a 15hp Yamaha 4 stroke outboard my problem is that the lever to tighten up the motor from turning does not keep it from turning when it is all the way to the right

I would check your fuel lines from the tank all the way to the fuel pump. It seems that you might have a pinched line somewhere. You can also bleed the fuel rail with the schrader valve on the end of the rail. If that wont fix it then you probably have a weak fuel pump.

Try contacting Yamaha direct or a reputable outboard dealers for the address, they will point you in the right direction, like all motors manufactured the makers keep a record of the serial number, i recently tracked this down for a friends Perkins Diesle engine that is running a generator in the middle of Spain, it turns out that his engine came from a 1912 lorry.

Good luck

I have one of these tilters and it's on a 2009 25Merc. I had to modify it because the pull handle is located lower on the back of motor.
