2 broken jet skis
Hey there, new to the forum but hoping someone may have some insight. My parents have 2 sea doo's that are both not working. One is a GTX 01, and the other is a 2008 or 2009 GTI 130 4tech, 3 seater. We are taking friends up this week and my parents are having trouble getting them fixed and I'm just looking for any ideas for if we may get them fixed asap.
The newer model Sea Doo seems may be a quicker fix. For the most part it seems to run fine, no maintenance warnings on the display and it runs at the normal RPMs. However it seems to run much louder than normal. It is like the engine/water noise is twice what it normally is. In addition when we tried to ski off of it, which we do regularly, it hardly had enough power to pull up the skiier. So for some reason it doesn't have the power to pull up a rider like it normally does and it also runs much louder than normal. We put new spark plugs on with no change in performance. Any ideas would be greatly appreciated.
The GTX 01 may have bigger problems. It seems to run okay after setting for a bit but very shortly after, like 5 minutes or so, it sounds like a cylinder starts to miss and then it progresses until it stalls out. It won't start right back up, but if you wait a minute it should start and then go through the process again. We changed the spark plugs and the spark plug caps with no better results. The history on this ski is that it did get water in it that seized the engine. However within hours of that happening we were able to change the spark plugs and get all the water out, and it ran fine. That was more than 2 months ago. With this one we are considering a cracked cylinder head or possibly a malfunctioning rectifier? Any logic to those ideas?
Any information or help with troubleshooting these would be great. We are trying to get a pro out to look at them but at the same time are on a time crunch because we are taking up friends in only a few days. My wife and I dread having to tell their son, who has never been on a jet, that they are both broke! Again thanks for anything you guys can point me towards.
Also on both ski's the gas was drained and the gas wasn't the problem.
