    Great deal. Wish it was 15 spline to fit my 150 Yamaha.

    wouldn’t fit regardless, you have a bigger lower end than his evinrude does…

    I have a 17p 4 blade that would fit your 150 with the right hub kit, it ran good on my Yamaha 150…

    What size should one run on a Yamaha 115 sho .....currently have a 13 1/2 X 17 Ballistic on 1800 Pro V....
    would like to run 30 miles an hour but keep rpm at or below 4000

    you need to prop your boat to run at max WOT rpm, it’s not recommended to prop to run at 4000 at WOT…

    what’s your current WOT RPM?

    yup should be 5600-6000rpm at WOT, prop for that rather than a 'desired' rpm/speed.
    Its much easier on your motor.
    I would guess you have a pretty good match with that motor and the 17p.
    Max hp on that boat is???
