Zodiac acti-v cavitation
Hi, hoping to find a solution for my cavitation issue. Iím new to the SIB inflatables, always had Jon boats previously. So, I have a zodiac club fastroller acti-v that was given to me and a 9.9hp 2stroke I had already, so when I get the boat just on plane it starts with the cavitation. Rpm revs and prop seems to be pushing air and then doesnít wanna go anywhere . Now I am using a 9.9hp long shaft that I have extended the transom to where the ventilation plate sits about 3 inches below transom base. I know the suggestion hight is 1-2in bellow transom but wouldnít being even lower prevent the cavitation issue? Should I raise it more or lower it? Iíve tried all the different trim positions and same if Iím solo in the boat or with a passenger.. would a hydrofoil help solve the problem?
Not sure which direction to go here and help and insight would be much appreciated.
