I went to the forum store and they suggest a 15x 9, 3 blades to replace my 15x10, 2 blades. The problem still because I want to go a bit faster without damage on my Yanmar 2GM20F. The only thing I will get with the propeller 15x 9, 3 blades is more maneuverability!
I have a sailboat Hunter 326 with a Yanmar 2GM20F. The actual propeller is a 2 blades 15x10 RH and I would like to change for a 3 blades to go a bit faster without damage for the motor. What Do you suggest?
Thank you to answer me.
