Slipstream Two Blade Folding Props

Seahawk, Martec Engineering and Austral Propellers have joined forces to bring you the ‘Slipstream’ range of Folding Sailboat Propellers.

Slpstream Folding propellers are a geared design. They were first released in early 2003, starting with the 2-blade version. The 3-blade version due in July.

Having been in the propeller business since 1981 and having produced the "Autostream" self-feathering propeller for over 20 years, this family owned company is now entering it’s second generation.

The Autostream propeller has become, what many believe is the best available product for the cruising sailor. It was developed and improved by cruising sailors using the world-renowned ‘Aussie ingenuity’ to enable production of quality stainless steel propellers at a cost comparable to bronze propellers.

Features:

•	All Stainless steel construction for superior life
•	Stainless construction matches the internal parts of saildrive legs; thus making them less prone to electrolysis
•	Blades and body 316L stainless steel (low carbon 316) Blade design has a large surface area for excellent thrust.
•	Unique blade geometry results in a smoother and more reliable opening of the blades, particularly when shifting into reverse while travelling forward.
•	Geared blades will close at slow sailing speeds, regardless of shaft position. It is not necessary to climb into the bilge to position the shaft. Blades will always open and close together.
•	Geared design keeps blades synchronized and allows blades to fold from any position
•	Blades swing on replaceable nibral bushes, these can be simply pressed out and replaced ,versus being drilled out to oversize or welded up and redrilled when worn.
•	Blade pivot pins will be secured at both ends with double screws for additional security, versus the normal one end. The side of the blade is held away from the inside of the body with UHMWPE (Ultra High Molecular Weight Polyethylene) 'Side Thrust plates' This is to prevent metal to metal wear of blade on body.
•	Urethane 'Bump Stops' to reduce the clunk of the blades hitting the full open stops when the blades open up in forward.
