Rampante 0 Report post Posted August 8, 2018 I got a 214 Supersport from 2014, with the VolvoPenta 270 and SX drive. Reaching 45.0 knots with standard aluminum prop the boat was delivered with. Not sure what rpm's I got with it on WOT. Got a small damage on that prop and changed for a 21" "standard" VP Stainless steel prop I easily could get hold of... Now (late season, I know but still) I get 43 knots at WOT 4500 rpm. Isn't that RPM a bit too low? What Stainless steel prop dimension should I go for? 3 blade or 4 blade? I think I get a bit higher speed at cruising and also better hole shot, but WOT seems low, but I'm not sure... Help out please!!! Share this post Link to post Share on other sites
Steve C 0 Report post Posted April 16, 2019 The manual for your engine should tell you the WOT RPM range. You should prop the boat to be somewhere in that range at WOT. A prop specialist should be able to help you, and may even be able to give you a few props to try for the performance you are seeking. Share this post Link to post Share on other sites
