For boats with apertures, our standard model, with its modern airfoil blade shapes and Flex (variable)Pitch Technology is still better than any bronze prop.

CORRECT PITCH AND DIAMETER ON THE FIRST TRY - GUARANTEED

We focus exclusively on props for sailboats under 40'. We've already tested many boat and motor combinations on the water, so we know the best prop for your application. And we guarantee you'll be satisfied, or your money back.

FLEX PITCH = PERFECT PITCH

Urethane props have a major advantage in that they flex more than metal. This means you get a range of pitches all in one prop. You'll be able to cruise quietly in calms (hull speed at 2200 RPM), go to maximum thrust when you need it, AND have great handling in reverse.

MODERN BLADE SHAPE

Cast bronze blades have a curved top and a flat bottom. This partly explains why many sailboats motor passably well in forward, but don't reverse well.

We updated the PerfectPitch blade with an improved airfoil shape, rounding them on both sides. These blade shape improvements alone account for dramatic performance increases, particularly in reverse

.

SAILORS LOVE OUR PROPS

Here's what sailors have to say about Perfect Pitch Propellers:

"It's so good in reverse, I backed up around the harbor for 20 minutes. It's fun."
-- Islander 33 / Universal Atomic 4

"CDI is much better going ahead in wind and waves."
--C & C 27 / Universal Atomic 4

"No comparison. 5.5 knots old vs 7.2 knots Perfect Pitch....I can now back down @ 4.5 with control. We did this for ¼ mile."
-- Jim Brown Trimaran / Yanmar 18 HP (2.62:1)

"Requires less power for maneuvering. It's hard to believe prop of the same size can make such a big difference."
-- Catalina 34 / Universal 21 HP (2:1)

"Cavitation and prop noise is a chronic problem with Corvettes and the CDI prop seems to have finally fixed it."
-- C & C Corvette 31 / Universal Atomic 4

"Super! No contest! This should have been my first choice."
-- Nor-Sea 27 / Yanmar 2Gm 20
