Think I'm being set up with either a Solas Titan or the High Rake Titan. Likely in a 19 or 20 pitch for this deep v walleye/multispecies ride. Heard Mercury props and maybe others work with Honda's as well.
Mercury owners manual for my 115 four stroke states "vent plugs not recommended". IDK the science behind why they don't need them. From my reading, four stroke already has the low end torque to spool up the engine and Opti (for example) needs venting to help engine spool up. My real world experience.. 225 Opti ran best with 2 med vents and 1 left out for my application and the 115 four stroke shook at idle when I tried med vents and hole shot suffered. Went to solid and it ran smooth and jumped on plane.
Hope we get it right in the first prop or two. I don't know if my resources or funds will allow me to go through too many props. I'm about a 50/50 bass & walleye guy. Suspect trolling hours will be less than 20% with a 112 up front. Love casting cranks for both!
Doubt you will hit 70 with a 23p but I could be wrong. My 225 has a different ratio lower on it turning a 26p to 6,100 rpm and the fastest I've seen is 74. I think mid 60's is achievable with the setup described by bigfram65
I'm getting 67-68. I'm not worried about speed. I wanted the reliability and gas mileage the Honda has. I've been out 5 trips sent I put it on and I've used less than a 1/4 tank of gas. That's running all over the lake. It's a huge improvement from the 250 HPDI I had.
