Over 60 years of ex- perience, together with a special interest in stain- less steel resulted in the first commercial stainless propeller—by Coolidge.
That's why Coolidge is known as the leading pro- ducer of stainless-steel propellers through 13 ft. in diameter and in 3-, 4 and 5-blade styles.
The Coolidge manu- facturing process includes the latest in all electric induction furnaces to pro- duce cleaner, stronger stainless alloy than is typically used in propellers,
Result—a tough prop that is hard to damage yet easy to repair.
Coolidge propellers may also be ordered in bronze, as well as control- lable-pitch blades and fairwaters in stainless or bronze. Propeller shafting is available to any specifi- cation in bronze, monel, steel or stainless steel.
We'll stake our reputa- tion on your complete satis- faction. Contact: Coolidge
