"I have an 1983 40hp mercury 2

"I have an 1983 40hp mercury 2 cyl. Took it out for a test spin and it ran fine after setting the idle up a bit. Then when we took it out and gave it full throttle it didnt act like it was giving all that it could. The prop that is on it is a turbo ss 10 1/2 13p. Does anyone know what prop is the right one for this motor? Or why it would run like this. The reason I know its not running as fast as it can, is because I have a similiar 25 mariner that runs faster on the same size boat."
