Sharrow Propellers Deliver More Benefits Than a Repower on this Sea Ray 320 with Triple Mercury 250 HP
SMOOTHER PLANING WITH FASTER TOP-END SPEED
19% BETTER FUEL EFFICIENCY AT CRUISE
The Sea Ray 320 is built for effortless entertaining and confident cruising, and pairing its triple Mercury outboards with Sharrow Propellers elevates the experience even further. With dramatically improved fuel efficiency, smoother acceleration, and noticeably quieter operation, Sharrow props let you cruise farther, host longer, and enjoy the water without compromise. Enhanced low-speed control makes docking and maneuvering stress-free, while stronger midrange performance and grip deliver a refined, responsive ride that perfectly complements the Sea Ray 320’s premium design and social layout.
On this Sea Ray 320, the Sharrow Propellers delivered faster speeds at all RPMs above 1000, and dramatically faster at on-plane speeds, including 16% faster at 4500 RPM, where most boaters run their outboards when on plane.
In this test, MPG tracks very closely for both props in the lower ranges. However, the Sharrow Propellers showed an advantage at all planing speeds, reaching a maximum of 19% at just under 35 mph. Greater efficiency equals better MPG, which not only means reduced fuel costs at the pump but also greater range, allowing more time on the water between refills and more confidence in making long runs between gas docks.
Look what happens at 2500 RPM. The Rev 4 propellers begin to slip badly relative to the Sharrows, and as the boat goes faster, that slip dichotomy becomes even greater. The Rev 4s are turning as much as the Sharrows, but as they go faster, the slip-gap widens, which is why the Sharrows are faster at the high end.
The “advance rate” is a measurement of how far the boat moves forward with each rotation of the propeller—a number nearer the pitch of the propeller shows a higher efficiency. As this test shows, the Sharrow’s had a higher advance rate at every rpm above idle, with a particular advantage between 3500 and 4500 rpm, the range where many boats are run most often.
