I am fairly new to jet skiing and bought this used along with a 900 3 seater. I had some work done on it last year, mostly rotted hose replacement and it now seems to be more unstable than it was. Looking at the engine compartment I seem two large black hoses that seem to go through the bottom of the hull and come up to the top of the compartment and are tie wrapped together but not connected to anything. When the thing flips over it gets a substantial amount of water on the inside of the engine compartment. Is water coming through these tubes when it rolls? What are these tubes for and is there anything else I could check to solve my stability problem.
