ARyland Posted March 3, 2016 Report Share Posted March 3, 2016 Looking for any input/recommendations on 4 blade prop options for a 2006 Redfisher 18 running a Yamaha 150 4 stroke. I've not actually "tested" top end numbers but best of my knowledge I'm running low to mid 50s top MPH turning 5700-5800 RPM with the current 3 blade. Thanks in advance !

wthree3 Posted March 3, 2016 Report Share Posted March 3, 2016 Turbo ultima 4 is an option. Haven't tried one but it is advertised as a good fit for flats boats. Link to comment Share on other sites More sharing options...
mdemott Posted March 7, 2016 Report Share Posted March 7, 2016 Yamaha has a prop site where they have run the scenario s for different setups. Has anyone used this? Link to comment Share on other sites More sharing options...
rdufren Posted March 10, 2016 Report Share Posted March 10, 2016 So far the best prop I've found for my 21 is a 4 blade Solas prop from Donovan marine. The best part about it is that my cost on the prop is only about $250! I'm seeing the best hole shot, mid-range and top end that I've ever seen with this prop. I'm pretty much 5mph every thousand RPM's from about 3500 thru 6000. Link to comment Share on other sites More sharing options...
