Frequent Sea is running a 3-blade 14X13 prop on a Honda 130. It's doing okay, we usually putt along at displacement speed anyway.
However, it only gets a bit over 5000 rpm wide open at maybe 17mph, so I'm dropping down to 14X11 this spring. When Dr. Bob said it was "fully equipped" he wasn't kidding. It's pretty heavy, loaded down with everything but the kitchen sink... no, wait, that's there, too!
The 130 Honda is just barely adequate for the boat at this elevation, but I love it. It just sips gas the way we use it on the slow, leisurely cruise. Powell is too cool to rush it unless you really have to make time and it will get up on plane and get you there if you need to, so all is good!
I'll let you'all know how it does in another month or so.
We're going to be in the middle of new home construction in September but am looking forward to seeing you'all on the lake. If not this year, next year for sure!
