So I replaced the carbon seal do to dust after a filed down my impeller. I’m guessing I made it out of balance and that’s causing the dust as there was none prior. So it and the impeller got replaced. I don’t remember if the (grove) near the engine goes into the bearing or stops short. Any...

I just put a rebuilt engine in my 97 gsi (717). I did a by pass on the oil injection and run 40:1 premix. Unit runs awesome. I plugged the line to the injection pump but still have the oil bath lines hooked up. While breaking the unit in today I kept getting the low oil indicator on my gauge...

So I tested the compression. The front has 125 psi and the rear has140psi.

I was thinking about just replacing the bearing. However I’m having a hard time locating one. I’ll check compression tomorrow. Tks

So I have a 97 gsi with the 717. It only has 149 hrs on it. We have had it for 12 years and put 74 of the 149hrs on it. It has developed a problem when it hits about 5200rpms it acts like it lost electricity cutting on and off. I checked fuel, coil rectifier, stator. All in range. I did notice a...

Ok found the problem a few days ago. The cheap POS stator unit I got feel apart. The generating coil came off the mounting plate and would loose ground and cause the ski to shut down. New unit installed all is well. I did take all mounting screws out on new unit and locktite them in.

Ok did fuel lines and rebuild of carb. Going to the electric system. I'm getting .05 ohms out of 2 yellow wires coming from stator. Book says 40-76. Could this be why it won't run at high speed? I did change entire stator plate and rectifier. Ski ran good for 2 days, on 3 Rd day is when it...

Ok I found the parts list to the carb. Does anyone know where I can get parts for it. I am striking out.

Does anyone know how much fuel line is needed to change all lines? The E box is dry no problems with water!

What fuel lines would you recommend?

New symptom I think, my info gauge (time rpm) while running it cuts in and out as if it looses power and you can hear motor want to die when gauge goes out. Checking for bad grounds now

This is what it looks like.

I have a pre carb filter that I put in years ago and have changed it before the start of this season! The fuel lines are original to the ski.

I have a 1997 GSI (720) i recently changed the stator and gen. coil. unit has run fine gor 10hrs or so since. Today the ski starts and runs until i try to accelerate, then it stalls. it is getting plenty of gas. I'm thinking ing. coil. Any ideas would be a great help. Thanks Al

Well we got it! 2 bad rectifiers and the stator was not built properly. There was a piece of isolation plastic missing. That's was make the short and blowing the fuse. Oh yeah that was on the bottom side of the coil. So I guess you were right about the 12yo at the end of an 18 day!!!!! 1st photo...

Ok, I don't think test light will work for that test. I did however use a volt meter on a ground and each one of the yellow wires and there is 12v at the rectifier. I then moved to the plug for the stator and tested both yellow wires and confirmed 12v in both. I get the same reading out of both...

I will have to order a new one and try it. Only 1 yellow wire was lighting up with tester. I will get new and try it. Thanks

great, thank you for all your help. the part # is 278-001-056

Ok so both new and old rectifier have power on one of the yellow wires. The old unit shows power on the yellow wire and the new shows power on the what would be yellow/blk wire.
