  • Prop recommendation for Pro Line 240 with 250 OX66

    Hey all, new member first post. Getting ready to hang a 250 on my 96 Pro line 240 Sport. Been running a 200 with an aluminum 14.5 X 17 prop. Looking for a recommendation for a stainless prop for this combo. In fishing trim the boat is heavily loaded with 5 to 6 middle aged overweight guys, 140 gallons of gas, Rhodan, 35 gallon livewell, and all the beer and ice we can fit. I would guess around 6500 to 7000 lbs total. Wanting a good midrange efficient cruise.

    I'd go Quicksilver Q4 14 5/8 x 17
    Same prop as the Revolution 4
    $569 from me, plus 45 for a hub kit.
    If you get one and decide you want a different pitch or style, you can swap out for $35 plus shipping.

        Ken, I finally got to open the motor up yesterday for the first time. Here are the numbers:

        4000 rpm 32mph 2.2mpg
        4500 rpm 37mph 1.9mpg
        5000 rpm 40mph 1.5mpg
        5250 rpm 42mph 1.3mpg WOT


        This is with only myself and half of tank of fuel. I'm pretty happy with the numbers except for the fact I could not get to 5500 with a light load. This is a new powerhead with only 8 hours on it now. Do you think I should go down in pitch or do you think the motor will loosen up with time?

          5250 isn't bad with a 250 OX66. The RPM range is 4500-5500
          How high were you trimmed for 5250? what happend if you trimmed higher?
          It might loosen up over the first 15 hours or so.
          is this the 17 pitch Q4 ?

            Yes this is with the 17 Q4. I was about 90 percent trimmed up. Might have got there with it trimmed all the way but I cant usually run trimmed that high offshore. I usually run this boat heavily loaded but haven't ran that way with the new motor yet. Will I be over propped with the 17 loaded if I can barely get there with a light load? I guess my goal would be to get to around that same number loaded up. I will be looking at another 2k pounds or so on fishing days from where I was with these numbers. Am I off base with that thinking? Thanks!

              Well, I'd load it up and see how much your speed and RPM drop, that will tell us how much pitch you need to drop to keep the RPM up.
