Thank you for all your input!
So we went out Saturday with the spare aluminum 14-1/2 x 19 39120 prop installed. Two people, medium load, 3/4 tank of fuel. Unfortunately, my tach took a dump and wouldn't read above 1500 rpm! The thing can be temperamental sometimes. Last time out my fuel gauge didn't work, which I have since fixed...but there's always something broken on an old boat! Ugh. I'll troubleshoot that tonight.
It was choppy on our 3 mile trip over to Fire Island, southeast wind, so it got smoother as we reached our destination; the barrier island blocking the wind. Still too choppy to run full throttle. As expected, the prop seems to take a bit longer to get on plane, a little less hole-shot punch, which I don't like, but not terrible. I wouldn't say we had any issues getting-on, or maintaining plane. This is an old prop, but was in new unused condition. The Great South Bay is mostly sand, but somehow I managed to put a ding in one blade's edge. -A vote against buying aluminum. I do typically raise the motor substantially and run in shallow waters regularly, to drop passengers and gear. Regardless, it's not a new prop any more... We kissed some paint bye bye LOL.
On our trip back, the wind had died down and it was a very smooth ride, and the prop performed really well! Unfortunately with the tack being in-op, I have no "data" to reference. I may pick up a new aluminum Michigan Vortex 15x17 (992003) from a seller locally and order the appropriate XHS 200 hub Kit. It will all be under $100 if I go this route. The size and profile of the blades looks similar to what we had been running for all these years...
