Cavitation plates are usually flat, thin plates made of stainless steel or aluminum. They’re mounted on the lower unit of your boat’s outboard or stern drive, right above the propeller.
The function of the cavitation plate is to decrease the occurrence of cavitation, a phenomenon where vapor bubbles form in water due to a drop in pressure. This happens when your boat’s propeller spins quickly, creating a low-pressure area. These bubbles can negatively affect your boat’s performance and potentially cause damage.
Your cavitation plate works by directing water flow straight into the propeller, helping to maintain constant pressure and minimize the formation of those harmful bubbles. It also lifts your boat slightly, reducing drag and increasing speed.
In essence, the design of the cavitation plate is simple, yet its function is vital. It’s a boat component you mightn’t often think about, but without it, you’d notice a significant drop in your boat’s performance. So, always ensure your cavitation plate is in good condition and properly adjusted for optimal functioning.
Benefits of Using Cavitation Plates
Now, consider the numerous benefits of using cavitation plates in your boat’s propulsion system. First and foremost, cavitation plates increase the efficiency of your boat. They help to reduce the drag that naturally occurs when your boat moves through the water, allowing your boat to go faster with less effort and fuel.
The benefits of using cavitation plates also extend to the handling of your boat. Cavitation plates make your boat more stable and easier to control, especially at high speeds or in rough waters. This enhanced control allows you to navigate more effectively and safely, boosting your confidence while steering your vessel.
Additionally, cavitation plates help to protect your propeller. They prevent bubbles caused by cavitation from reaching your prop, thereby reducing wear and tear. This can considerably extend the lifespan of your propeller, saving you significant replacement costs in the long run.
In short, the benefits of using cavitation plates are immense – from improving your boat’s efficiency and handling to protecting your propeller. So, if you’re looking for a way to enhance your boating experience, consider adding cavitation plates to your vessel’s propulsion system.

Frequently Asked Questions
What causes an outboard motor to cavitate?
Cavitation in outboard motors can occur due to various factors that disrupt the normal flow and pressure conditions around the propeller. High operating speeds cause the propeller to rotate rapidly, creating low-pressure areas where water vaporizes into bubbles.
These bubbles collapse violently, causing noise and potentially damaging the propeller. Other causes include dirty or irregular hull surfaces, improperly installed equipment like transducers, and the use of damaged or inappropriate propellers. Maintaining proper boat balance, ensuring the propeller is the correct size, and regular maintenance of the hull and propeller can help mitigate cavitation.
While you’re doing maintenance, always make sure to check whether you need a replacement skeg as well, or individual replacement parts like shift shafts, drive shafts and water tubes. If you don’t know what is a boat skeg, here’s a simple answer.
Where should the cavitation plate be?
The placement of the cavitation plate on an outboard motor is crucial for optimal boat performance and to minimize cavitation issues. The cavitation plate should be aligned with or slightly below the bottom of the boat’s hull. This positioning helps in maintaining proper water flow over the propeller, preventing air from being sucked down which leads to cavitation.
The plate’s optimal position can slightly vary depending on the boat’s design and operating conditions. Typically, the cavitation plate should skim just above the water level when the boat is going at full speed. Adjustments might be needed based on the boat’s performance and characteristics; this can sometimes involve trial and error to find the best height setting
How do I know if my boat is cavitating?
Identifying cavitation in a boat involves recognizing specific signs during operation. Common indicators include unusual noise or vibration coming from the engine or propeller, a decrease in speed or efficiency, and erratic steering or handling. Additionally, observing air bubbles or foam in the water near the propeller or experiencing a loss of control during acceleration are telltale signs of cavitation.
It’s crucial to address cavitation promptly to prevent potential damage to the propeller, engine, or other components of the boat’s propulsion system.
What does prop cavitation sound like?
When experiencing prop cavitation, the sound is often described as a distinct rattling or buzzing noise emanating from the engine or propeller area. This noise is caused by the rapid collapse of air bubbles formed around the propeller blades due to low pressure.
As the bubbles implode, they create vibrations and turbulence, resulting in the characteristic sound associated with cavitation. It’s important to address this noise promptly as it indicates inefficiencies in propulsion and potential damage to the propeller and engine components
