Re: Is a 115 good enough on my Leader 19'
Since you said Rude and 115 hp, you are probably on the prop rating side of the hp scale. Having run a 125 on the powerhead rating side of the scale on a heavy 18' tri hull with a reduced pitch prop for water sports, I could still get 39 out of the rig. Your hp is probably about what mine was and you have a fine match lined up. I think I was running a 13+ x 17P SS on mine but I could pop up two kids on slaloms with the rest of the family in the boat or me on a slalom with them in the boat; no problem. If it weren't for the load, I could have easily gone to a 19 or maybe even a 21 and would have gotten well over 40.
