MARK III ELIPTEC : 2 BLADE BRONZE NON-GEARED "RACING PROPLLER:
The latest MARTEC FOLDING PROPELLER; improved and perfected continuously since 1964, the ELIPTEC is the lowest drag propeller available for sail boats.
Drag is due to 3 factors:
1. Lowest Drag (most streamlined design)
2. In the Water Installation
3. Shape and lowest cost
The ELIPTEC is better than any other propeller on all 3 counts.  Its simplicity (only 4 parts) and rugged design combine to make it the most reliable low drag propeller as proved in repeated round-the-world racing and cruising.
ADVANTAGES:
意o gears to jam or break.
意o holes in your boat (windows) necessary to check for weeds or blade position.
意o swimmers needed to position, feather, and lock or remove weeds from the propeller.
意o shaft lock needed.
意o un-feathering during a race or cruise.
Reverse the Mark III and all the old myths about folding props disappear...  The ELIPTEC patented design provides reliable reverse.
