Understanding Propeller Function
Boating enthusiasts who make regular use of their outboard engine and propeller do not always understand how a propeller actually works. They may have in mind the action of a fan because fans, unlike propellers, are often seen while in operation. A propeller working underwater is a more complex operation.
A propeller represents the very last stage in the power train or propulsion system of a watercraft. In essence, the job of the propeller is to change torque, created by an outboard engine, and change it into usable thrust that will propel the boat forward. Chrysler outboard propellers, like all propellers, are specifically engineered so that they will be able to control the revolutions per minute produced by the engine. When the throttle is wide open, Chrysler outboard props should be able to hold the revolutions per minute to the range the motor’s manufacturer has specified.
If a propeller can do this, it is one sign that the propeller is a good match for that engine. This is because if a propeller allows a motor to exceed the recommended revolutions per minute, the result is excessive wear and tear on the drive train as well as poor performance. To get the most out of Chrysler outboard propellers there needs to be a good match between propeller and engine. Otherwise, the engine will not perform at peak efficiency today and neither will it pass the test of time by lasting for the long run.
