Seahawk and Austral Propellers of Australia, in collaboration withMartec Engineering of California, have joined forces to bring you the“SLIPSTREAM” range of Geared Folding Sailboat propellers in 2003.

✔ All Stainless Steel construction for superior life.
Blades and body use low carbon 316L grade stainless steel.This being the same metal as most prop shafts & saildrive internal parts is less likely to promote electrolysis, the most common killer of props ✔ Five-year warranty against material andmanufacturing defects ✔ Combined know how and experience of three wellestablished marine propeller companies ✔ An enhanced product at a comparative price ✔ Large Blade area for excellent thrust,
with uniqueblade geometry resulting in a smoother and more reliable opening of the blades, particularly when shifting into reverse, whilst travelling forward. ✔ Saildrive models feature ‘fail-safe’ cushion hubs,with integrated safety stops. ✔ UHMWPE (Ultra High Molecular WeightPolyethylene) ‘Side Thrust plates’ prevent metal-to-metal wear of blade on body.* * ✔ Blades swing on replaceable Nibral bushes,
these can be simply pressed out and replaced, versusbeing drilled out to oversize or welded up and redrilled when worn.**

2 and 3 blade“GEARED” designs

Gears keep blades synchronized,allowing the blades to fold back properlyregardless of the propeller position, even at low speeds - No crawling into the bilge to position the shaft when racing ✔ ✔ Unique Polyurethane ‘Bump-Stop Pads’ to reducethe ‘clunk’ of the blades hitting the full open stops when shifting into forward and eliminates the wear of the blade hitting the body.** All wear components are user-serviceable,
Available to marine suit shafts from 1” to 1 1 / 2 ” and Saildrives with “self-service” kits available when the time comesto refurbish the propeller. (** Included in Kit) Sizes from 14” to 20” diameter 41 London Drive, Bayswater, Vic. 3153AUSTRALIA www.seahawk.com.au Phone: +61(3) 9761 1633 info@seahawk.com.au Fax: +61(3) 9761 0727
