    Stainless steel propeller

    Looking for the best prop for 2020 190tw bass tracker with a Mercury 90 hp four stroke.
    What pitch and brand work best ?
    Not looking for speed
    the boat is fine the way it is.
    any help would be greatly appreciated

    I would get a Powertech nrs3 in the same pitch as the stock aluminum prop.

    I agree on the Power Tech prop. Also why did you get such a small motor on that boat? It should have a 115 at least.

    I agree with the above as Mercury props tend to be more expensive than Powertech.

    I got it used, super clean boat ! I wanted the larger motor (115) but 5 -8 mph did make difference to me

    My 90hp came with a 21p prop! Do not buy another 21p prop as replacement on 90hp motor. Double check before you commit $

    ignore the should have bought a bigger motor crowd!

    if it were me I would want no more than 17-18P

    The 90 has 2.33 gears, so prop accordingly. I run a 19" X7 and a 20" Laser on my 2.07 geared 115 ProXS. I'd go with a 4 blade, too.

    Some act like it's a crime to not max out the hp even when it's not their boat therefore they shouldn't care anyway. As long as the motor pushes the boat good enough for the owner that's all that matters.

    He could put a 115 ECU on it and take the restrictor ring out of it and it wouldn't be so bad.

    I've heard the 4-strokes don't react to that nearly as well as the 2-stroke did. All that said, I stand by my comment where some people just don't care and are happy with what they have even if they know what they're missing.

    If the ratio isn’t show On the leg somewhere look it up.

    the 2021 4S 90 has a ratio of 2.07
    the CT version has 2.38.

    I posted a graph of my boat performance with the stock 21p. Look for “prop seems wrong”. After 4600 rpm it just made more noise!

    2.33
