New results with the Laser II prop.The fuel comsumption dropped a little comparing the 4 bladed Trophy plus and the laser II (13,25 x 20)
The engine is much smoother running with this prop, and also the fuel consumption is better.
Boat 1: Montauk 170 with Laser II,1 person and 1 tank (6 gallon) of fuel.
Boat 2: Wahoo offshore 1750 90 suzuki 4-stroke (weight boat ± 450 kg)) with
1 person and a and 20 gallons off fuel.
Boat 1: max rpm 5700, top speed 44,1 mph. Fuel comsumption
13,0 ltr same trip as Wahoo.
Boat 2: max rpm 5500 with alum.prop 14 x 23, top speed 42,2 mph. Fuel consumption this trip 10,6 ltr.
I think that the trophy prop. is to heavy for this engine,
and thats why the fuel consumption dropped with the laser II.
This prop is also better than my first Vengeance prop (13,25 x 18)It has a better mid-range and the top speed is
higher. The hole shot with te Vengeance prop is better, buth the max rpm. (6200) is to much!!!
