After a couple posts ago I finally had the chance to get all my numbers with a new prop. Here goes.....We went from a 14 1/4 x 19p to a 14.5 x 17p prop. My 4.3lx mercruiser's max rpm's are 4400-4600 and yesterday I really watched the rpm's and we were running at 35mph at 4400 rpm's. When I went almost to wot, the rpm's went to almost 5000 and there was still some throttle left and I didn't want to chance scattering the engine. The 17p prop. seemed to help getting out of the water a bit but with 2 adults, 2 teen boys and my 6 year old daughter the boat still seemed to lug. I'm hoping the addition of my Smart Tabs will be more beneficial. But with those numbers am I good for the prop? Thank you.
