fish2live Posted March 10, 2010 Share Posted March 10, 2010 i have a 04 johnson 90 4 stroke on a 1750 fishhawk. I am currently running a 13.75x21 4 blade solas alum. i am getting about 5400 rpms and around 36-38 mph. looking to get a stainless is any one running this setup with a stainless? what are you getting mph and rpms? and what size stainless are you running? thankssteve Quote Link to comment Share on other sites More sharing options...
setterguy Posted March 10, 2010 Share Posted March 10, 2010 If I'm not mistaken you want to be a little higher on the RPMs right? 14x19 might do the trick...If my calculations are right you should get another 400 RPM's out of that. I know my 4 stroke Yamaha calls for 5800-6100 WOT. Quote Link to comment Share on other sites More sharing options...
fish2live Posted March 10, 2010 Author Share Posted March 10, 2010 5500 rpms are the target rpms to run with this motor. i am looking to run a stainless hopeing for a little more speed and less blow out when taking corners on plain. Quote Link to comment Share on other sites More sharing options...
marine_man Posted March 10, 2010 Share Posted March 10, 2010 You are correct on your RPM's... I would suspect a 20 pitch prop is going to make the most sense, given you're towards the upper end of your rpm band.marine_man Quote Link to comment Share on other sites More sharing options...
