faster propeller for 2004 50 hp 2 stroke Mercury motor

[kakhaj]

I am looking for a faster propeller than what I have, which is model number 48 73134A40 12P. Near the propeller, on the motor, is written 12*22 and 1.83:1, if that helps. Thank you.

Can try a larger pitch prop as long still within rpm range for your model motor.
