So I just bought a 14.5' Wahoo with a Merc classic 50 that runs beautifully. It has a 12P prop that was damaged so my buddy gave me a SS 13P and I took it out for a cruise. Me (280lbs, GF 130, and friend 200) full of 8 gallons of fuel and boat that weighs 675lbs. It planed but it took a while and my friend had to get on the bow then it gradually got up on plane, it was a big slug though. So I threw an aluminum 11P on today and took it out, just me and my gf and 3/4 fuel, surprisingly it just kept on plowing until she moved up towards the bow then it hopped right up on plane. It ran pretty good and sounded good and kept on plane no problem. My buddy said the 12P was perfect but he was mainly solo and much lighter than me,and he claims to have had 5 people in the boat and it took a while but got on plane no problem. My question is given the weight of the boat does it sound about right that the 11P is the way to go? Not sure of RPM's but from the sound of it it sounds somewhere in the neighborhood of 5200RPM? Any thoughts would be appreciated.
Thanks in advance.
