98 seedoo GTX issues

[ShaneM78]

I have a 98 seedoo GTX it has 82 hours on it and it starts great and idles flawlessly but as soon as you touch the throttle it floods itself out any thoughts on what the issue could be

How do you know it's flooding and not just dying?

So long as its not the RFI model I would check compression and if good get into the carb

 

[ShaneM78]

When I hit the throttle it boggs down like it’s fouling out a plug if you let off the throttle it continues to run, I check the plugs and they are all wet

 

[alldodge]

Sounds like it is flooding, need to get into the carb

 

[ShaneM78]

Thank you I’ll try to figure that out after work today

Here's the carb breakdown

Hi. This could be most commonly, either a battery (or related) issue…or to do with the rave (power valves) valves, depending on engine.
Have you jump started the ski from a running engine just recently ? This can blow the rectifier very easily on these. Means that a decent or charged battery will start her no probs…but won’t be getting charged.

Not an expert so I'll await your reply. He said it was a GTX and not a GTX RFI. It's my understanding the only the RFI (I owned one) does not use a carb and uses injection. I did replace my rectifier because of issues

Hi AD. You’ve got me thinking for a minute there. But, yeah…there are rave valves on the carb 951 engines. These were used in the gtx models in the 90’s for sure. Maybe the 787cc did too even. I had a Di model from 2001. Before, around and maybe even after then…there was rfi models too. But pretty sure that most from the mid to late 90’s Gtx models were usually carb 951 engines. They had rave valves I’m sure.

I’m so sorry it is the RFI we’ve taken everything do the throttle body off and cleaned it throughly I know it hadn’t run in a year I put a new battery in it

Check the power valves (if it has them) and make sure it’s charging from the rectifier. Could it be a fuel filter issue ?

Update: if we hook up a hose to the machine it runs and idles great but as soon as we dunk it in the water as soon as you touch the throttle is boggs out

 

[alldodge]

Have you checked compression?

 

[ShaneM78]

Have you checked compression?

I have not I’ll need to get a compression tester or take it in somewhere to have it tested

 

[alldodge]

Might be able to borrow/rent one from a local auto parts store

When doing the test, disconnect all plugs

Thank you I’ll let you know what I find in the next couple days what should the compression be around

Hey @QBhoy what should it be, I'm thinking around 120?

Had exact symptoms on my 2004 RFI GTI- Check the flame arrestor- My flame arrestor was dirty, cleaned it and changed the plugs as they were fouled. On the hose there is no load on engine, impeller isnt grabbing anything spinning air. Flame arrestor being dirty cuts off airflow but fuel is determined of throttle position sensor

Another possible contributing factor on an RFI is resetting the TPS. I spent 3-4 seasons fouling plugs because the fuel mapping is off if the 0 point for TPS gets out of whack over time. Was changing my plugs every 2 weeks during the summer eventually broke down and bought the Candoo Software, took longer to load than reset the TPS.

Spot on with that AD, as far as I’d be after.

We tested it and it was right around 150 we changed the fuel filters as well and checked the flame arestors and as soon as we hit 2500 rpm is Boggs out otherwise it purrs like a kitten until we try to go and bam no go
