Prop issues

[Dapper Muis]

Hey Guys.

I went fishing this weekend and got a thorough testing of my boat with the motor and the prop.

Boat: Rebel 440
Motor: 75HP Mariner
Prop: 4 Blade D4 x 12.5 X 21RM
Max Speed: 62 kmh - 65 kmh
Max Revolutions: 4100 rpm - 4300 rpm

My Questions are:

1. Im not sure what pitch the prop is that im running at the moment?
2. What pitch prop would be a better option?
3. When im driving at full throttle are the Revolutions correct for the setup of Motor and Prop that im running?

Please guys i need all the help i can get cause i want to get the most and best performance out of my Boat.

All the help and info would be much appreciated.

Thanx

Shoe this is difficult if you not running the boat and understand what she is doing. The revs however looks a bit low, the ideal revs should be between 5500 and 6000. This should give you optimum speed.

The four blade might give you a slower start but will give you more byte and stability in the turn. I am not really a professional on this and what I am telling you is purely based on my experience!
