Hi, new to the fourm. Ok....this weekend 08/26, my daughters were ridding our 1995 Sea doo GTX, when it suddenly died. I checked the fuses and found the ignition fuse blown,also changed the charging fuse, and found it was slightly melted but still working. I changed both and started the engine, it ran for about a minute then died, also the low voltage light has been on for some time, but it ran fine. I was wondering if the battery is bad? it has 12.5 reading. Any info will be great! Thanks Tom

Blown fuses

That is good compression. I think it may be the rectifier, which converts the AC power to DC to charge the batteries. It also limits the charge to about 14.5 volts so that it wont short things out. Get a multimeter and start testing to make sure they are in spec.

Joe, I put the new rectifer in today and it works fine. No more blown fuses, however the low voltage light is still on, but all readings are within normal range. I'm going to put a new battery in on wed, and see what happens, but any way everything runs fine. Joe, you are the man! thanks for all the info it realy helped. Tom
Broken manifold bolts
Joe, after replacing the rectifer and battery, my family and i rode the waverunner all day on Fri 8/31, when i came back to the dock and put the hose on i noticed water comming from the the exhaust pipe right were it connects to the exhaust manifold, 3 bolts and a stud. I found that the two motor mounts came lose ( Not Sure How they hold the motor down ) and i guess that the motor moved and hence the stud broke and one bolt. What i need to know is were i can find a used manifold, and is the motor a 712? 1995 GTX.

low voltage light
My low voltage light stays on like yours did.
After being stranded like you, I have determiend that my PWC is simply running on battery power alone. (Thus short rides do not pose a problem)
Only when I am on a long ride the GTX RFI goes into "limp home" mode a while and then later completely dies.
The charging system is not working...obviously...but no fuses are blown.
I have a hard time thinking that the magneto is actually blown, thinking that some other electrical part (hopefully a small one) is blown.
Any ideas, and would the rectifier be it, since my fuses are OK?

Low voltage Light
The rectifer converts AC to DC power and keeps the voltage at a charging rate of about 14.5V. My Battery is good I check it when we ride,the dealer checked the system but everything in order. Try checking your voltage regulator with a volt meter,it may be bad preventing the system from charging.If your fuses blow all the time then its the rectifer..LOL

engine alinement
Joe, I have all the parts to fix my waverunner. My question is when i put the engine mounts in how due i know if the engine is alined? Maybe you can give me a heads up on how to aline the motor. The shop said after replacing the shims the motor might need alinement. Thanks Tom

Sorry if my reply didn't help...guess that is what I get for staying up late...
I just checked the shop manual, and it says to pay attention to alignment, but that it won't properly install if not aligned. You have to have to slide the shaft through the housing of the jet pump and into the engine, and if not aligned it just won't go in. You'll have to just figure out how to position it so that it works, and loctite it from there. Also, the manual suggests the use of an engine alignment tool if necessary.
Hope this helps

rectifier
My 1996 GSX also has shown the low voltage light while riding and my battery always drains down and needs recharging. I read your response about the rectifier needing to be changed, can someone that is not mechanically gifted do this or is it pretty intense to change out?

blown fuses suck
I'm having a similar issue on a 94 gts and a 95 gtx the 5 amp fuse will blow I pull it out repl it as soon as it gets power it will blow immediately and I cannot attempt to start the engine same problem on both.
any ideas would be greatly appreciated I'm thinking of getting the shop manual on ebay I'm not too familiar with these motors

can anyone help
i have a 1997 sea doo bombarder 717 my son took it out and it died he tried to start the sea doo would not start he got towed in we jump the battery and it started my son started back out on the water and it died. when we got home i tried to start and the starter was draging then it would not start so i had the starter rebuilt replaced the silinoid replaced the battery found out that my number 5 fuse was blowen so i replaced it but it keeps blowing replaced the regulater still having the same problem does any body have suggestion

Same problem here
I have two sea doos. 95 gtx and 96 gti. I put them both in the water two weeks ago. The batteries were dead and I jumped them both. Both started for a little while and then when i tried to accelerate they would die. I tried jumping them again and blew the 5 amp fuse. I have since replaced both bad batteries, which i could not bring back to life, and now the 5 amp fuse blows everytimg I put the terminals on the batteries. I killed both of the skis. They are both doing the exact same thing. From what I read on the forum here that happens due to idiots like me jumping the battery or running on a bad battery.
I have read another thread on here to check for a short to determine if the MPEM is bad or not but I have some questions. I though I also read that the rectifier could be bad too. Can someone reply with a simple how to on how to test with a multimeter whether it is one or the other. I am fairly new to these skis but I dont mind tinkering either. This may be helpful for all the other guys with this same problem.
Thanks for any help!!

Yep....at the rectifier, if you can unplug just the 2/3 yellow wires, unplug them, then install fuse. If pops, then unplug red wire from rectifier, if still pops, MPEM is bad. From there, you want to find on hear...ALLTHINGSCUSTOM....and get ahold of him.
One other thing, never jump these skis, with running vehicle.
If your rectifier has one big plug, or 2 plugs, disconnect, then try the fuse.

5 amp fuse clarification
Just to be clear, if you disconnect the two yellow and the red wire from the rectifier and the fuse does not pop then it is the recifier that is bad? If the fuse still pops, then the MPEM is bad?
What does it tell you when you check it with the red wire connected but the two yellow unhooked? If the 5 amp fuse does not pop, then the recifier is bad, MPEM is OK?

Problem Solved
I did all the tests per this thread and determined it was the MPEM. I sent it out to ALL THINGS CUSTOM and popped that baby back in. The seadoo runs like a champ. I appreciate all those that posted in here and we are lucky to have this forum and ALL THINGS CUSTOM.
My other ski is still down with the same problem. I am sending that one out shortly to have Mike at ALL THINGS CUSTOM fix that too.
