What is a cavitation plate on a boat?
A cavitation plate is the adjustable metal plate that runs along the bottom of the transom on a V-drive. Some people call the flat metal plate on an outboard or outdrive a cavitation plate but the correct name is anti ventilation plate and cavitation and ventillation are not the same. It is similar in function to Trim Tabs. A cavitation plate is used to adjust the trim of a V-Drive and keep the nose on the water. Here is a link to a picture on PerformanceBoats dot com In this picture of a V-drive, the cavitation plate is anodized red.
What is an outboard motor cavitation plate?
A cavitation plate is a permanent horizontal plate on the vertical shaft of the outboard right above the propeller. It sits just at the water level when the boat is up on plane (ie: flush with the bottom of the boat, for a planing style hull).It prevents 'cavitation' of the propeller ie: prevents air from the surface of the water being picked up by the action of the propeller. Cavitation drastically reduces a prop's effectiveness & efficiency; basically a cavitating prop is pushing some air rather that just water. Over-revving can also result.
How do you know how high to place an outboard engine?
On the lower leg of the motor, just where the gearcase bolts on, you will notice the anti-ventilation plate. Just above this plate, (the "plate" resembles a flat, horizontal fin), many motors have a second plate. You'll want to hang the engine where the bottom of the boat falls between these two plates. You can go a little lower than this, but not where the boat bottom falls below the bottom plate. This will likely cause cavitation and or engine overheat.
