Another great and informative video, thank you! I have a 96 GTI and last Saturday I found myself in 6" of water with sand below, unfortunately I panicked and rather then killing the motor, I hit reverse and then proceeded to get back in forward and drove out. Within 1 minute I heard a loud, high pitch winding sound (only one time, lasted about 5 to 10 seconds) and the ski began idling extremely rough and lost power. I tried cruising back with no throttle but within 5 minutes the engine temp light came on, I shut it down and got towed in. Since then I have done a compression test, examined the spark plugs, bumped the starter with plugs out, examined the shaft, impeller & wear ring, blown out the the water intake line (felt clogged for half a second and then blew through, thought that was it but no cigars), ran water through the coolant system in both directions, runs fine in the driveway but horrible when you put it in water. Next, I guess I will check out the impeller shaft reservoir and bearings to see if sand got in there possibly. I would have thought this would've been a common, easy to diagnose scenario, but I'm not finding anyone else that has experienced this problem. Any suggestions would be greatly appreciated.
Lol, I said "what" until I started hearing about mods! Any mods to that machine would be a motorcycle on water for handling!! Probably very fast and fun! Stock that already performs
Mine has loads of play, im worried the thrust bearing might slip off into that little groove in the shaft and when i accelerate it will get smashed up? Any thoughts on that?
I was told the impeller shaft is supposed to have a little play like that, I asked if it was normal and they said yes. "They " are the guys that run westside.
i have a question , What could stop the pump from pushing water into the engine? I hook up to the hose connection and comes out the weep hole ,, I put the GTI in the water and water does not come out weep hole. I feel its the pump as that is where i isolated it. I back flushed and seems clear.
You didn't use a bearing installer tool. PN 295000107. Did you set the Needle bearings sub flush to the manufacturer specs? Each bearing has a different setback clearance. 1.5 to 2.5 and the other 2 to 3 mm.
Are there any places down there that dyno PWC? I used to have a Suzuki SV650 that I did a lot of work on, and had it dynoed. The dyno showed what I needed to fix to get it correct.
@12:15 you can see your thrust bearing has been chewing on the back of the pump. The washer should be between the pump and bearing, not on the other side of the pump.
Yah im ordering sponsons soon, only issue I have is I dont know how to trim this thing, as there is no VTS on here, and I thought about ordering OEM trim tabs but dont know how they mount on the hull
