The Mark IV Geartec: fourth generation blade design for saildrive applications

These blades are specifically configured for geared folders, providing the best combination of forward and reverse thrust we have ever achieved.

Saildrive Installation

On many of today's sailboats, the saildrive has replaced the traditional engine, shaft, strut, propeller configuration.

Saildrives present some unique challenges for propeller design, in which case this is best solved with a geared prop.

This is where Martec's forty years of engineering know-how comes into play.

Saildrives require geared folding props because their blades must be able to fold with the prop stopped at any point in its rotation.

The Geartec® is an innovative approach for saildrives, eliminating problems from earlier "Pre-Martec" geared folding propellers.

Using our experience, we carefully engineered a better prop. a much better prop.

Recognized Innovation

For forty years Martec has been known for its elegantly simple design, and have been the leader in folding propeller engineering and innovation.

Martec propellers are relied upon by knowledgeable racing and cruising sailors all over the world
