Cavitation Or Jumping On The Waves

"Is jumping on the waves (

"Is jumping on the waves (causing the prop out of the water) too harmful for the engine? I mean can I do it a few times during my ride? Will the REVs immedaitely go up as the boat is in the air?

I noticed when I do a steep turn, the engine REVs itself down. I wonder if there's a system that prevents the engine from damage and automatically deccelerates it in case of cavitation.

I have a 2007 Volvo Penta 5.0GL.

Thanks!"
 
"revving like that can damage

"revving like that can damage the engine as there's a release of energy, it will cause damage to something at somepoint. You will also damage the prop, as cavitation can cause the water to boil damaging the surface of the prop.

The process of cavitation occurs when pressure decreases (while using a propeller). This causes water to boil at much lower temperatures. When the bubbles from this boiling burst they can cause pitting to occur on the blades of the prop."
 
Engine RPM reduction in turns

Engine RPM reduction in turns due to increased drag on hull in sharp turns and increased load on engine.
