Boat propeller S7

foldingsaildrive3-blade

Geared design keeps blades synchronized, allowing the blades to fold back properly regardless of the propeller position, even at low speeds. Sizes from 14 to 18 diametre All Stainless Steel construction for superior life using low carbon 316L grade stainless steel. Being a similar metal as the internal components and shaft of saildrive units, it is less likely to promote electrolysis, the most common cause of prop failure Large Blade area for excellent thrust, with unique blade geometry resulting in a smoother and more reliable opening of the blades, particularly when shifting into reverse, whilst travelling forward. Polyethylene thrust plates* on either side of the blades prevent metal-to-metal wear of blade on body. Blades pivot on replaceable Bronze bushes*, these can be easily pressed out and replaced, compared to the traditional over sizing or welding/redrilling Easily replaced Polyurethane Bump-Stop Pads reduce the clunk of the blades hitting the stop faces when shifting into forward, plus eliminates the wear on the back of the blades and the body Blade pivot pins* are double screwed* at BOTH ends for increased security of blades All wear components are user-serviceable, self-service kits are available for when the time comes to refurbish the propeller (items with * are included in the kit) Saildrive models feature fail-safe cushion hubs, with integrated safety stops. The user can easily replace the cushion hub, although it is unlikely it will ever wear out. Five-year non Commercial/Charter use Warranty against material and manufacturing defects
