diameter is determined by measuring the distance from the center of the propeller to the tip
of one blade and multiplying that figure by two. Pitch is expressed in the number of inches
a prop will advance in a solid medium in one revolution.
Operational characteristics of your boat, including its speed, may change due to several
factors: atmospheric conditions; additions of extra equipment and accessories or passengers;
marine growth on the bottom; and, engine condition. Other factors include damage to the
prop(s), tides, water temperature and direction of wind. Some of these factors are directly
correctable by repair or maintenance. Others are beyond human control.
INCORRECT PROPELLER APPLICATION CAN CAUSE ADVERSE HANDLING
CHARACTERISTICS. DO NOT CHANGE TYPE OR SIZE OF PROPELLER WITHOUT CONSULTING
YOUR COBALT DEALER!

Some Cobalts are standard equipped with stainless propellers. In this instance, do not
substitute aluminum propellers. Adverse handling and top speed characteristics may be
experienced.

If you need extra pulling power, you can obtain this by decreasing the pitch of your
propeller(s) by two degrees. This will not endanger the engine or drive unit as long as
the manufacturer’s recommended top RPM’s are not exceeded.
