New here lots of questions!!!!!! Help 96 GTX? Maybe?

A jump pack is a bad idea on a seadoo. You can easily fry the mpem that way. There are stickers on the ski warning of this. I'd use a good charged battery for the test.

Ok I will charge up the battery and give it another shot

 

[JDawg965]

I am putting a new battery in today and I will re compression check it then go from there

 

[JDawg965]

Ok well the ski only has 58.7 hours on it tried to test it again, and the gauge must be wrong it sounds great I don't know

I'm following this thread....I also own a 96 GTX.

What is wrong and what sounds great?

What is status?

IF you end up thinking of a rebuild. Check out the company SBT they have reman motors for a very reasonable price. For the 717 motor when I ended up with eBay low hour bottom engine crankcase, a SBT reman crankshaft and reused my old top end my cost with me doing the work wasn't that different from having bought their reman motor already done by them. They sell a reman 717 for $750 just something to check in on if you decide new motor or rebuild route

Good luck

*****UPDATE*****

Ok I was finally able to get back on here to post... I put a brand new battery in the seadoo and checked the compression, it's still at 90 on the dot.. ;( it sounds good cranking maybe it's my gauge.. I ordered the 1/4" fuel lines and new selector valve. That should be here some time this week. I figured I would replace the lines first and go from there... the seadoo has only 54.9 hours on it so I am not sure how the engine would be so beat up. But who knows... let me know what you think!

Try another compression tester. If it reads the same you probably have a sick engine. If the second tester reads significantly different, try a third tester.

 

[JDawg965]

I was thinking of just pulling the motor opening it up, in the garage it will give me a winter project to mess with

 

[JDawg965]

Can't find another tester with out buying a new one, so I'm getting it into my garage tomorrow and I'm going to start with replacing all the fuel lines and selector valve and see if I can get her to fire up, if she does good if not then I will probably just start to take it apart and do a rebuild

 

[Ankeneyou]

Unfortunately it can run perfectly on the trailer with low compression, then not start in the water. I recently bought a backup Actron from amazon for $19 shipped and it reads dead on with my other.

I guess it's an innova gauge I just looked. They are now $17.40 shipped if you have prime.

To be honest wasting your time until you verify good compression 90 psi isn't good and it won't run on the water with 90psi

 

[Coastiejoe]

You can rent for free from most local auto parts stores.. I agree with 1of500, if you have poor compression nothing else matters...

 

[JDawg965]

Just doesn't make sense but I will use Amazon and grab another I figured i would be pulling the engine to do a rebuild that was my original plan, so it doesn't really matter to me. It has not ran it's been sitting for a couple
Months at least since I bought it, I know it was on the water in July this year. Then it was stolen then I bought it from insurance company it has 5x.7 hours all original parts so I was planing on pulling the motor anyway figured it would be trashed so I don't care if it's 90 psi
