Need Prop Help

[Jeff k]

I recently put a new 2022 Suzuki 140 on my champion 171, I am just now at the process where I can run at full speed for a few minutes at a time and the engine is supposed to run 6200 rpm MAX, with myself and my fishing partner and our gear we hit 6200 RPM quick and the motor has more in it.

I can do a one time exchange with the dealer on the prop I'm trying to figure out should I go up one pitch or two how much RPM will I lose per pitch?
Anyone running my set up? what are you getting for speed? and what prop are you running? I just want the max I can get out of it, not looking to race it lol

Usually 1 pitch = 200RPM but not sure on a Suzi!

My buddy had a 171 with a 140 Suzuki he bought new around '01 or so. I can't remember what prop he ran, but I think he would get mid to upper 50s depending on the load. I know he wasn't happy that my old 168 was rated for a 150 and would run him down.

Currently running just at 50@ 6200 I'm going to try a 25 pitch and see how that works I may have to have a deep pitch slightly
