Wow, that's significant. Do you have the ski running ok again?

So I have gapped and replaced spark plugs, looked up through the intake grate (wear ring and impeller look great) and made sure the oil was not overfilled. The last run got to 47. I have not checked for spark, would it not throw a check engine light if a coil was not firing? What is the best...

Looks like part#295100839 will fit.

Thank you for all of the helpful replies so far! It has both the yellow and green key. I was using the yellow key and the screen indicated normal key. I am going to check spark and compression and then re test. It's supposed to be nice on Thursday. So, I changed the plugs and checked the oil...

So far I've changed the plugs and checked up in the intake grate area. The impeller and wear ring look good. The oil looked to be on the high side. I extracted about a half quart out. The weather has sucked here (St Louis area cold and or raining) so I can't test ride.

Lay under the ski and look in the intake grate. You will be able to see if anything has been sucked in there. If all clear, hook up water and start the engine. Then turn the water on to flush. Only run for a minute at the most. Then turn water off, then engine off. Never have the water running...

I was thinking plugs. It only pulls 6300 rpm. I wonder what max rpm should be? I had trim up and in sport mode.

Just got this gti and it's lame. 77hrs, using yellow key 43 mph. WHY?

I don't try to modify junk.

Yes, you can spray liquids through it but does not create the required pressure for circulation. Really sucks as I bought it last year to replace a wallered out pump and did not get a chance to test. I ran out of time and warm weather.

It's figured out, aftermarket jet pump=junk-no pump water. Has only one orifice (hole) instead of three like the oem.

Got a used oem pump off of ebay and it now pisses. YAY.

No quick disconnect. I have blown through all. I am certain it's the aftermarket pump.

Eastman spec reflects use for petroleum. I have this on a GTX for over a year. No Issues. Do not fear.

I use Eastman 1/2" ID reinforced braided vinyl tubing. You can get it at Lowes. Works perfectly.

Nevermind, they do interchange.

There is a 4 or 5 mm allen head screw at the throttle stop, turn it in to achieve 3000 rpm idle out of water. Starboard side of motor. Pretty easy to access. I have a 99 and 2000 rfi, bumped them both up.

Will the rave valve (guillotine) and the screw on cap (piston) interchange from a 2000 RFI to a 97 carbed ? 787 of course.

Very good point. I will recheck them.

Has anyone had issues with an aftermarket pump housing not supplying cooling water to the engine? I have this 2000 787 GTX RFI that had a trashed pump so I replaced with the aftermarket one. It wants to over heat and and not peeing out the back. I blew through all of the hoses, made sure the...
