I also think the 12 pitch will be the best for your boat. I run a brass 13 pitch Michigan on my 14 ft. Alumacraft (aluminum} runabout, with a 35 Gale. It’s much lighter than your rig. A 12 pitch is to light for my boat, unless it has 4 adult passengers. I would start with the 12p prop, and check the WOT RPMs with a tachometer.. then you will know for sure. And yes, a one inch pitch change can be the difference of night and day on most boats. Lugging the engine from to much pitch, will cause a drastic increase in fuel consumption, and is generally hard on the engine. To low of pitch, may result in over revving the engine, and cause poor performance.
