  • prop for repower Dusky 278FAC

    Ken,

    I am putting a new Merc 300 on a 2007 Dusky 278FAC. Can you point me in the right direction for a prop choice? I don't know what I don't know so anything you can offer is helpful.

    Thanks
    Greg.

    Ok, so they claim 45 MPH with twin 150 Evinrudes. https://www.boattest.com/review/dusk...open-fisherman
    Guy over on TOS had a 250 and got 42 MPH.
    So it sounds like 45 MPH for 300 HP is pretty realistic on expectations.

    With Mercury props, the ECO is going to be a great all around prop. but the lowest pitch available is 17 and I think your going to be low on RPM if were only going to get mid 40's.
    The Powertech OFS4 in 15 pitch would be my first choice. If you don't load up very heavy, you might be able to swing a 16 pitch.

      Thanks Ken. The quick answer I got from Dusky was 15x17, 15.5x17 or 16x17. I'm looking forward to the testing.
