| Cavitation is when your prop is losing it bite. You can tell, because your rpm's will go up but your speed won't. You will also lose your bite in the turns and if you have a fast boat this can be dangerous. Cavitation is normally caused by having your engine too high on the transom or a prop that is not right for your boat. Also a prop that has been reworked improperly can cause this.
The boat manufacture can usually tell you how high to run your engine on the transom and what prop to run on your boat.
You should never raise an engine on the transom without a water pressure gauge. You can destroy your engine very quickly, if it's not taking in enough water. Are you sure you didn't just have a rooster tail off the back of your boat. A rooster tail that doesn't go higher than your cowling is normal.
What boat, motor and prop do you have? What are your rpm's, water pressure and speed? Maybe I can help. | |
