The GORI folding propeller has amassed a record and reputation unmatched throughout the world of propellers for cruising and racing.
Geared Blades
Geared blade design ensures that the blades open and close together giving less vibration ahead and astern.
Gain a Full Knot of Speed
GORI folding propellers reduce total drag by up to 35%. This results in one full knot of improvement in speed under sail.
Full Power Astern
A GORI propeller gives you the optimum thrust in reverse by virtue of it’s propeller blade shape and profile. It does not rely solely on centrifugal force to open the blades as do many other folding propeller types.

Benefits of GORI Propellers
- No rotation under sail. No strain or loading to the transmission.
- Blades have both camber & curve (aerofoil) to their shape.
- Increases efficiency (thrust) under power and over a greater Rpm range.
- Lower propeller noise from blade wash due to curve of blade.
- Dramatic reduction in prop-walk (almost non-existent).
- Overdrive function allows for a pitch increase over normal of approx. 2″-3″.
- Simple installation. No gear & blade assembly or pitch settings to make at time of install.

Testimonials
For the last five years my boat, a Catalina 270, has struggled to get through the water under power, especially against a tide or current. After talking with Geoff at AB-Marine, he suggested a GORI folding propeller. I installed it in the spring and it has made an amazing difference. The speed has increased with less rpm’s, the boat is much more maneuverable and responsive in forward and reverse and I have no trouble making my way through an oncoming current. The new prop has been the best upgrade I have made yet.

Since it came from the factory six years ago our 46 foot sailboat had a fixed three bladed (speed brake). In a quest for more efficient sailing speeds we recently purchased and installed a GORI 3-blade Folding prop. To our delight our new GORI prop has increased our sailing performance one to two knots and we have also gained over a knot while under power. Soon we will leave San Francisco Bay and begin our cruise to the south and on through the Panama Canal to the Caribbean. With our new GORI prop we will arrive at the fun anchorages even sooner.

The Gori 3-Blade propeller has proven invaluable. Our boat’s prop-walk-to-port drove us into neighboring boats until we changed to your 3-blade folding propeller. Now we can easily and safely power in reverse to starboard. Another pleasant surprise was the forward power that a combination of our little 18hp engine and the Gori 3-blade over-drive function provides as they lift our 32ft sailboat’s bow to surge across the bay.

Just want you to know that the 3-blade GORI prop is fantastic!
I consistently get at least a 1/2 knot improved performance over my old 2-blade folding prop and the boat doesn’t bog down in head winds & seas.
Thanks for steering me to this product, it is worth every cent. Sorry I haven’t had a chance to run flat water RPM sea-trials for you, been too busy racing and doing deliveries to regattas.

Hi Geoff, I am writing you on route from Newport to Martha’s Vineyard. The GORI 3 blade 15” x 12 x 3 RH propeller has performed beautifully for my Catalina 350 with Universal M35, rated at 35hp, 3000rpm, with the 1.88:1 ratio, RH rotation, 1.00” dia. shaft. I just want to thank you for your assistance, after what we think was a tressle strike a few days prior to the parade when we discovered that the blade had come off our old Autoprop. Thanks again.
