Well I don't really know the diameter of the nozzle. I believe the boat is capable of riding just fine. I have talked to the original owner, and he did not have the problems I'm having. He took it to Hi-Tech and had them set it up. I've talked to Duane at Hi-Tech, and he pulled the ticket up and we went over it. He took it out to the lake and got some time in the boat. Granted it was three years ago, but there was no note of it still having a problem when he was finished. Plus the owner swore by his work and setup. So that leads me to believe it was right. But he then sold the boat to the next owner, and he said it ran 81 MPH GPS speed until the motor dropped a valve. So he rebuilt the motor, then he took it out and sucked up a glove and trashed the Impeller. He then supposedly went from a A impeller to a AA. The next time out with the boat, had carb and ignition problems. That's when I got it. So now I have to look at all the parts, and see what is wrong. I do know the boat had solid mounts in it,which it has rubber now! crazy.gif I really don't know what the impeller is because I have a receipt that says it was an A not a AA. I really need to go to a river, by my self, and start dialing the boat in. Problem is I always have a bunch of friends and family that want to go with, and I've read where these hulls don't like allot of weight in them. I also have noticed that as I burn the fuel down, it tries to take a set more and more. Everything I have found on this hull so far, points to the ride plate. Tom even worked on one with V-drive plates on it to keep it down. So I know there is an inherent problem somewhere. But I think the ride plate will be part of the solution. And Will probably realize that it won't like rough water. It tried a couple of times to take a set. But something agitated it. It may have even been me!
