Hi All,
I have been working on ATV's and most anything with an engine for many years. I have owned personal Watercraft in the past. Right now i am trying to help a friend with his SeaDoo XP. After much research it seems it is a very common problem.
The XP runs great on the trailer, Around 7K RPM. It runs all the way up until the rev limiter kicks in. On the water it starts right up and pulls hard until 4K RPM and that is where it stays. I have read countless threads about this problem. But, I either found someone had the problem, started trouble shooting, fund the problem ( usually the rectifier ) and they are up and running again. A large portion of what I read.. Someone has the problem, starts troubleshooting and never finds the problem even after they have replaced numerous parts and completed all the troubleshooting. And third lots of threads never showing the outcome or if they ever got it fixed.
I would like this to be the thread that goes from start to finish in diagnosing and repairing the issue.
I have obtained the service manual and started testing components.. The thing I found funny is that at the end of electrical testing procedures it states.. " Even though everything may test ok, that does not mean the part is working, only replacing the part will be the definitive answer" Anyone that would like to chime in feel welcome... Thanks for any help.
