Fish n ski, I run an '01 trophy 175 w/ 115 ficht. I just upgraded prop to 13 7/8 x 17 ss prop. I haven't had boat out not loaded with gear, people or fuel. I'm getting about 38-39 loaded at about 5400 rpm. I believe your beam is wider than mine so u may have a few more pounds of hull weight. My previous prop was a ss prop but diameter was closer to 12" and was cavitating like crazy, actual had burn on slag. Max speed win old prop was 36.3 at just over 6k rpm. Guy I bought boat from couldn't figure out why he couldn't keep the paint on the prop.
