Hi I have a 2007 130 sport and I would like to get a new prop, it has a mercury 40 4 stroke and I would like to know which prop would give me the best performance overall? Current pitch is 14
Thanks

Whatever boat you have, need to know the model number of the prop and speed and RPM at WOT. Also where is the outboard ventilation plate relative to the water surface while on plane, trimmed out.

Your right I just looked it up its A 130 sport. And I have the stock mercury Blackmax (the prop says 73138A40P14) on it but the tach doesn't work so I'm not sure what the rpm is at WOT, and the next time the boat is in the water ill check the ventilation plate.
Thanks for the help

OK.
2007 Sport 130
Without a tach you are basically out of luck optimizing the prop.
You can only rely on what other members are using which may not be anywhere near close to what your boat needs.
I would suggest getting your tach fixed or purchase a new one.
The most important gauge on any boat is a tach. With a tach, a person knows they are not going over redline on the motor and risking blowing it up. A tach also helps to determine the correct prop for you boat.
