Cavitation Part 2

Non-inertial cavitation involves tiny bubbles in a liquid being forced to oscillate from the input of energy. The intensity of the input energy is insufficient to cause total bubble collapse. This form of cavitation is less harmful than inertial cavitation. In fact, non-inertial cavitation can be used to clean delicate materials, like silicon wafers.

Cavitation occurs in outboard motors often as a result of a foreign object, like marine vegetation, getting caught on the lower unit, interrupting water flow into the propeller blades. Making sure your outboard engine is clean and free of debris will help prevent harmful cavitation. Also make sure to change lower unit gear lubricant and inspect the powerhead annually. As always, Evinrude xd100 oil is the best to use on your outboard engine.
