Since you are new, I will try to describe why it is acting like that. To really understand how these boats work might solve a lot of your questions. The basic concept of jet boats is jet propulsion. Normal prop boats use an external prop to push the boat along. Jet boats use an internal impeller. Think of it like a big fan blade. It sucks water up through the bottom of the boat and pushes it out the back through a smaller opening, creating force and moving the boat. That is the basic concept. When there is a restriction to the water flow, this thrust is greatly reduced. If there is a leak anywhere on the outlet side of the impeller, you get no thrust. This loss of thrust is called cavitation.
1. The intake on the bottom of the boat can become clogged up with weeds, sticks, and other debris. When this happens, the impeller no longer has water coming through it and therefore you have no thrust to move. If something has been sucked up in the past, it has probably damaged the wear ring. The ring is there to give a little and prevent the impeller from just being tore up.
2. It should be very fast to get up on a plane. Faster than a lot of other boats. If it feels like something slipping, you may be experiencing cavitation. Could be something as simple as needing a new wear ring. A wear ring is like a gasket that incases the impeller.
Soooo...That is more than likely your problem.
