    No one can be wrong that often so it has to be deliberate.

    This prop is still available. TYD for $350. for one more week. After that I'm pulling the post and sending it to Marks Props to get the pitch changed to 19", like my new prop, and keep it for a spare.

    Bump for a great prop. I ran a Spitfire X7 17 and 19 on my Ranger 681VS and those props were awesome for that combo. Great holeshot, great bite for turning, good speed. Highly recommend this prop.

    Do you think that prop would perform well on a Merc
    150 carb that on a older Ranger 3 series, 18’9”. 1350 lbs ?
    I know that is a tough question but just thought you may know

    I have this prop on my Ranger RT 188, Merc 4 stroke. I can never get my RPM past 5200. Does Mark fix that? Max speed is 43, which is really fine for me, normally cruise at 30 lol.

    If you have the 115, and your current prop is a 21 pitch, I'd ask Mark to change the pitch to 19" and tune up the prop too. You'll get another 400 or so rpm. As for RPM, are you getting that figure off of the RPM gauge on your dash or do you have the Mercury Marine Vessel View w/Mobile App, which will give you a more accurate RPM reading. Either way, going to the 19" will give you better rpms.
