I have run a 25 renegade for years and it would run high 60's at 5800 rpm at 3" ptp. I got into some gravel and messed it up and going to send it to get fixed etc. I got a 26p original raker that looks new. Put it on boat would run 61 at 5900 rpm. Dropped the motor to 3.5" and it is running 63 at 5800 rpm. Think it needs to go deeper. My boat usually like them high but I am struggling with this prop. I figured if the motor is turning the rpms with it that I would get more speed than this..
