When handling the assembled propeller, avoid being pinched by the opening or closing blades.
Do not operate the propeller when close to people or animals in the water.
Stop the engine immediately if you notice any strange sounds or vibrations coming from the propeller.
Check that the propeller functions in both forward and reverse before each voyage.
Shift gears at idling RPMs only.
When sailing, the propeller must be stopped for the blades to fold/close.
With a mechanical transmission; stop the engine and put the transmission in reverse gear to prevent the propeller from turning.
With hydraulic transmission; while boat is moving forward under sail or due to momentum and engine is still running, engage reverse gear and shut down the engine.
