    Performance Reports Now Available ▼
    The award-winning Sharrow Propeller™ performance data shows the incredible performance attributes of the Sharrow Propeller™ on different boat/motor configurations.

    GALEON 325 GTO / TWIN MERCURY 400 HP OUTBOARDS
    Sharrow Marine collected data on a Galeon 325 GTO with twin Mercury 400 HP outboards. The boat has a L.O.A of 32’ 9” and a beam of 10’ 11” and a deadrise of 21. Dry weight is listed as 14,200 lbs. and the estimated test weight was 15,200 lbs. The customer asked us to develop a propeller that would get the boat on plane at a lower RPM and keep it on plane at lower RPM to allow a greater range of cruising speeds.

    Full release and more information is available at Sharrow Marine's website.








    KEY COLLECTED DATA TAKEAWAYS


    • The Rev4 propellers needed 5000 RPM to maintain a planing configuration. The Sharrow Propellers were able to maintain plane at 4000 RPM, greatly extending and widening the usable on-plane speed range.
    • Both sets of propellers achieved similar WOT RPM levels. 6225 RPM for the Revolution 4’s and 6325 RPM for the Sharrow Marine props.


    • The Advance Rate of the Sharrow props was much higher throughout midrange RPMs and contributed to being able to achieve a wider range of cruising speeds.


    • The 0-30 acceleration of the Sharrow Propeller was 10.76 seconds vs 16.53 for the Rev4 propellers

      Engines aren't even in peak power band and the stock Rev 4 is still faster, try again with a 13 pitch Rev 4 XP and it'll be better in every aspect..

      Kinda looks like the only benefit is in the just under planing speed and barely planing. Thats where its more efficient than a revo 4. Everywhere else its the same. So if you wanna go the speed that noone wants to go then get a $10,000, otherwise stick with a $1000 prop.

      Yeah 400R is 6400 to 7000 rpm, This thing ain't even in the range, lugging it too much!
      Well I'm wrong 6200 to 6800 for standard 400
