The old 2 stokes were fitted with aluminium 17 inch props.
I have no intention of changing props as I am happy with the performance.
With 2 people on board and half fuel it revs to 6300 rpm at 63 km/hr.

I am happy with the fuel economy with each motor doing around 3.1 - 3.2 km/lt @ cruise.
Those are very good numbers! Do you have a T-top or bimini top?

What speed do you get at around 4,800RPM?

I trialed mine with a 15 pitch prop and had some problems. Mainly related to the fact that mine were 20" leg engines. The 25" leg is not available in my country. I was going to space them but decided to sell and purchase new engines with 25" legs and make new pods.
