Hello all
I have a 26ft heavenly twins catamaran with a two-year-old Tohatsu MFS20E with a 10x7 three-bladed Tohatsu prop which works ok but marginally better than the old 9hp high thrust Yamaha.
i am thinking of fitting a 4 bladed prop to see if this improves matters in terms of torque and speed
Tohatsu wide open throttle range for a twenty 5400-6100
Thoughts and suggestions are much appreciated.
