Witch propeller

[weerix]

Hello,

I have a Mako rib of 5 meters behind with a 1992 Mariner 75 HP 2-stroke
Here is a normal propeller mounted made of aluminum.
Can someone explain to me if I screw one another, among which I would like to look Pitch eg
it is obviously the speed benefit.
This afternoon the boat tested and come with 61 km / h (can something faster, I think)

Another question When I set the engine in reverse sometimes it rattles looks the of the motor not far enough in his reverse position
Is this an adjustment or is there something defective?

Thanks for any responses.

What pitch is your propeller and what RPM are you getting at full throttle?

61kmh is quite quick though!

Yes the cable needs adjusting at either end.
