How to fix cavitation in inflatable boat or dinghy?
There are two reasons for cavitation problems. First, is an incorrect or damaged prop. The second, and most likely, is that the boat is not fully or properly inflated. If the boat’s chambers are not fully inflated, this will cause water disturbance under the boat tubes, and cavitations as a result. Please make sure that the boat is fully inflated by using hand pump. Do not use only electric pumps or compressors to inflate the boat. Use a hand air pump to pump up all boat chambers until they are hard to the touch. In general, once you feel that it becomes difficult to pump any more air with a hand pump, it means that the chamber is full. You can lightly knock with your hand on each compartment and it should feel hard, not soft. The most recent response from a customer who fixed cavitation by properly inflating his SD365 boat was: “Thanks, I did what you said and went out in the ocean today and my boat ran great, really moves with this honda 20hp outboard.” More Info about Cavitation due
