1996 Seadoo Bombardier GTX problems.... Need help

Thanks for all the help

All I know is if you want to sell that handlebar, finger throttle and start stop switch from your donor ski I will be the first in line!!!

 

[1996 bomb]

Anything I dont need to use on the GTX is going to be sold off. My wife has drawn a line at my parts collecting.

 

[CReynoldsMIZ]

Sounds good, just send me a PM if you want to get rid of it. Hear that [MENTION=51824]Matt Braley[/MENTION] , I got dibs!

 

[1996 bomb]

Will do!

10 char

No matter if you have any other issues, I can tell you that you have connection issues or a bad starter.

If it won't crank with the plug in, you have an amperage issue or dirty connections.

That said, if the voltage gets around 10.5 volts the MPEM pretty much shuts down. Poor connections affects both amps and volts but seriously affects amperage.

thanks again to all

Among the obvious things it also sound like when he tried to start it he jump started the ski and most likely blew out the MPEM. And just looking at the pictures and from what you are saying you need a new solenoid, a new ignition coil, and new battery and starter cables.

When you put this ski back together make sure your oil lines, especially the injector lines are replaced, also replace the oil filter.

Where are you located, judging from the amount of corrosion, is this a salt water ski?

Thanks for your help. The black tub the solenoid and other wires sit in was filled with water. That could cause a lot of connection issues. Do you know if cleaning the connections is good enough or would sitting in water ruin anything in that little tub that I need to replace?


Pic below shows the tub that was full of water. I drilled a hole in the bottom to drain and when the ski is fixed I can patch it if needed.

A quality cleaning is normally all you need.

Remove the wires, sand the ends, dry the box out, clean the box out, put back together with dielectric grease.

In your case, I would do this with EVERY ground and hot wire. It will be well worth the effort.

Yes, even the PITA wires at the starter.

thanks again people

 

[1996 bomb]

yep its all good now

Does anyone have anything to say about the pistons/cylinders? I read on here a bad rectifier makes them run like they have low compression, could the guy have mistaken that for a blown engine (maybe he blew the rectifier jump starting the ski?)??

I cant be that lucky can I?




Progress Update : The ski cranked with a single plug in but not with both installed. Checked the battery and it was low, left it on slow charge over night.

Things to do this morning. (fell free to add to the list)

1. Check battery while cranking.
2. Check for spark to plugs
3. Pull carbs and clean them
4. Possibly replace all the fuel lines (may have the grey lines, will add pic and you tell me?)
5. Be thankful father gave me enough free lines and clamps from his work to do a complete ski :cheers:

Please Take my Advice (as LouDoo said) JUNK THAT BATTERY !! Replace it with a top quality sealed one. I had problems with both of my skis and was constantly charging batteries and trying to figure out they slow crank .I replaced the batteries in both of them and I've enjoyed a trouble-free summer, that's the first thing you do if the batteries in question just get rid of it. Trust me on this one

thanks for the help

Gotcha! Only problem is until I'm sure the motor isnt trashed I really dont want to spend anything on the ski. If the motor is blown I'll sell it off to someone who wants to invest in and fix it.

If you got it cheap enuff you can recoup your money and just loose time spent but I hope you get it going bcuz thats a fun ski to ride

 

[Coastiejoe]

( does PITA stand for power wire or is this a waverunner term or special set of wires?).

PITA= Pain In The A$$

thanks for the help

Why would you assume starter is bad? I agree with Lou and Crofoot about batteries in general.
Just because it charges, and voltage tests OK, and it cranks with one spark plug, doesn't mean it is up to the full task.
Unless you have a battery load tester to verify that it is still good when drawing 80 amps, it is probably past its useful life.
If you don't have a load tester, then measure battery voltage while cranking. If is is below about 10 volts (or 9.6v) then it is no good.
It is easy to be fooled by batteries acting like this.

Also, even if you are cranking with both plugs in, the MPEM can give various problems when it doesn't have enough power.

then measure battery voltage while cranking. If is is below about 10 volts (or 9.6v) then it is no good.
It is easy to be fooled by batteries acting like this.

I want to reiterate this. The ONLY real test is to see what the voltage is WHILE cranking the engine. Both plugs in,,,

If you do determine it is the starter, yes, rebuild yours. Do NOT buy an aftermarket.

 

[1996 bomb]

fixed. it runs great

 

[Coastiejoe]

I think we were typing at the same time. Posting again to suggest you read post 18.

You can test the battery in the ski while cranking.

 

[1996 bomb]

thanks for all the help

 

[Coastiejoe]

Do you have a meter. Anything to read volts?

 

[1996 bomb]

thank you joe

 

[Coastiejoe]

No but I'm going to get my daughter a new fishing pole for her birthday at Walmart, would they carry them?

Also here is a video of the motor sounds, it said it would be done processing in a few minutes.

[video=youtube;uJpNc7m5Oe4]http://www.youtube.com/watch?v=uJpNc7m5Oe4[/video]

Yep. They will carry them

A cheap one will do all you need. I bet a DVOM (Digital Volt Ohm Meter) can be bought for around 10 bucks.

I have three meters. Some were large money as I use them on computer brains and other sensitive items that require a low impedance. This is not an issue in your case.

thanks for all the advice
