Doug,,, that was my concern all along. Does the 72 really handle the 14x4w or am I just slowly destroying the engine? Guess the answer lies in how many times the motors been back to Horizon for service. At least twice.
It did get hot running the wide prop and sometimes during hot or cold days I'd have to switch to the 13x4w .
Still I think the 14 size prop pulls the Do around best. And this narrow prop looks like a keeper and might save me another set of bearings.
