I split (blew) the rubber tube hose that connects the engine exhaust to the waterbox and had it checked out and thought it was maybe just regular wear and tear. The ski is a 2000 1100 STX DI but it only has a little over 100 hours on it. Replaced the hose and it ran fine just like before. Question is, is there a cooling hose that could be plugged that I could undo from the engine and see if there is any restriction and if so where would that be? I have been on the Kawasaki site looking at the parts diagrams to try and see what cooling hose may be blocked that I could try and flush out. This ski is new to me and I really don't know much about flushing it if it would get some debris in it so any help would greatly be appreciated. Thanks in advance if anyone has any help.
