Well every boat cavitaites. I'm going to refer to the sv27 because of the fact most of you have it .
Well as we know it is surface drive. takes a while to get on plane which i find weird. Hydro do that only because the prop is in such a way you have the throw it to get on plane. and cats are not like that . my cat has great acceleration also does the villain Both boats do not cav like the sv27.
But a sub drive is different. great for everything but speed. lighting fast reflexes. you know why? It is because all of the rudder and all of the prop is in the water, so it can take full use of every thing unlike the surfacedrive, where only a bit of prop and rudder is in the water during a run.
Sub drives are good for rough water.
not many boats cavitate on rough water. most boat when hit rough water tend to run more lose. there is a smaller ride pad which mean more speed and it just hops over the waves. when you hear you motor rev out; you know that the prop is out of the water . But that is no cavitating because once it hits the water it grabs and keeps moving you forward.
