sounds like your doing pretty good actually, the best i ever got out of my 4 stroke on the minnow was 27 mph with only me and a few rods and that was with a 12 pitch prop, always wanted to get a smaller one but never did, you could go with a 9 and that would probably jump you out of the hole nicely but dont think your gonna see higher speeds than what your seeing, your speed will change a few mph's depending on shifts in the wind, current etc...

Hmmmm....

Yeah I was satisfied with the speed but why do I feel like I'm hitting the rev limiter?

RK, I doubt you're hitting the rev limiter, but it's always a possibility given slip and the JP/setback. I'm no expert there.

See my comments under your update thread about what I found that motor likes for propping.
