  • Need prop recommendation: Ranger Bay 2300 with Yamaha F300 and Atlas 4" Jack

    I searched and found nothing on this setup. Any recommendations for overall performance prop and pitch? I have Lenco trim tabs on it. May need to get out of shallows now and then, so I assume stern lift would be a good thing. I plan to have a 4" Atlas jack plate as well. Thanks in advance.

    Boat and Motor specifications below.

    Going though emails on that boat.
    These are the props/numbers that people originally emailed me with. I suggested whatever prop, but don't have any other numbers from them after that.
    3.3L F250, had the HS4 22 pitch, ran 5200 rpm at 39 MPH
    225 Optimax, 17 pitch Mirage Plus, ran 43 on its best day, didn't say what it ran on a "normal" day
    250 SHO 21 pitch Enertia ECO, best day ever 5100 at 51 MPH, "normal day" was 4500 at 43 wide open


    I'd expect high 40's for the boat with an F300 on it.
    The prop I'd recommend assuming you have a jackplate would be a Quicksilver Q4 in 17 pitch.
    Same prop as a Mercury Revolution 4, great all around 4 blade, still fast, gets along with the jackplate well.
    If you can turn 6000 RPM, you'd be getting high 40's, maybe 50 MPH.

    If you get one from me and decide you want a different pitch or style, you can swap out for $35 plus shipping.

      wow, the SHO only got 5100 WOT on the best day? 5100 is not a happy place at WOT for an SHO, am I right? Unless he was trialing his boat loaded, 4500-5100 WOT seems very low.

      I was able to squeeze 5800 and 43mph with the OX66 200HP that I just sold on the Ranger 2300. That is with a Yamaha M-17 prop. Running with only one person, 30 gallons of fuel, and only the starting battery. My boat has a T-Top.

        Well, those were emails from people coming to me for help. so yes, That isn't a good place for a sho.
        Just trying to get a realistic speed estimate.
        It would appear most are over propped when they come to me, as they must be propping them for a really light load.

        You got 43 MPH with 200 HP, so 300 HP would theoretically run 53 MPH under the same conditions, but you said that was really light as well. So I'd still say high 40's maybe 50 is a realistic number to work with. and I'd still go 17 Q4.

        But for top end speed with 30 gal of fuel, I bet we could put a 19 3 blade Tempest Plus on there, and get mid 50's.

          this 24’ Skeeter is very close in weight to my ranger. Impressive numbers, but was able to turn 6100 rpm with a 19P and 75gal of fuel.

          Im going to borrow my brother’s 21P Tempest + next week for a baseline.

          Got the 300 installed, just waiting on my Garmin for gauge data.
