1996 GTI Runs fine OUT of water, but not IN water

[inyadrms]

I just bought a 1996 GTI - the owner said it had issues with running. He took it to the lake and it ran fine then all of a sudden all it did was idle. Once he took it out of the water it ran fine again. (revved engine and all)

He took it to a shop and they said it needed a new carburetor rebuild. They did the work, he took it to the lake and the same problem.. He took it back to the shop and they said it was the fuel relay? He had it replaced, and decided to sell it. Never went back to the lake to see if it truly was the issue.

I have yet to take it to the lake yet, but was wondering if anyone had any other suggestions before I did. I am completely new to the waverunner family and know nothing about them. The gauges also don't work. Any ideas?

maybe this will help & maybe not , i had the same deal w/ my xp last summer, check the fuel lines & see if they are grey or black , if grey get rid of them , also the carbs have filters that plug up from the grey lines as fast as you clean them , i would start there , & work your way down hope this helps
