Hey guys!
I posted a few weeks back about some skis I was trying to buy and naturally, my first 3 tries all fell through/fell on deaf ears. However, a friend of a friend happened to buy some brand new jet skis and sold me his 97 and 00 GTXs on a trailer for $2,500!
This post is going to focus on the '97, since currently the '00 is waiting on a new pump (ran without oil for a while, cannot get the impeller off the shaft
). It is also worth mentioning that both are premixed and have been since long before I owned them.
I have already done a jet pump service on the '97; everything checked out pretty good on that end. It will need a new battery, but that's not a big deal. I did find a water jacket leak on the exhaust and got that welded up, so we are all good there. (One of) the previous owner(s) had already gone through and replaced every fuel line at some point. The ski has 275 hours on it, but I believe it has had a rebuild. It fires up very easily (when the battery holds a charge) and runs shockingly quiet compared to the 951 in the '00.
The only real problem I have is a bog between 3500 and 5000 rpm. On the water, under partial OR full throttle, it will reach about 3500-4000 rpm, then struggle, then rip like a bat out of hell from 5000 to 7100 and cruise at an indicated 53-56 on smooth water. My understanding is that it most likely wouldn't be the low or high speed screws, as those correlate more to throttle position rather than RPM, and this is always in that same RPM range. After a little reading this morning, it seems like possibly a RAVE valve problem.
Anyone have any suggestions or experience with this?
