Hello,
I am starting this new thread to see if anyone will have a genious idea about my ski. I am appealing on the experts here.
I had the engine replaced at the dealer last week (GTI LE 2003, one carb and 717 engine). All this was replaced fixed:
- New rebuilt engine directly from BRP;
- New oil pump;
- New rotary valve;
- Carburetor rebuilt with complete rebuild kit (yesterday) and they also replace some kind of valve/nozzle (made of copper I think and as small as half a small finder)
- Fixed muffler (there was a bit of loose where the water exhaust connects). Muffler was welded (seemed OK to me).
- Jet pump inspected and oil changed (jet pump is only four years old and less than 35 hours wear because previous owner, a cousin of mine, had it rebuilt in 2011).
- Of course, new plugs and total check up.
Ends up that the ski is in deep trouble: lack of power, will not go faster than 38 mph, hard to start, no acceleration, engine stalls at idle, smells gas when trying to start it.
When I got the ski back, I thought that the extra burn-in oil directly in the tank was causing the problem but after three tanks and nine hours later, I realized that there was a problem. So I brought back the ski to the dealer.
They tried some adjustments on Monday and I went for a water test only to find that the issue was still there. Then they decided to rebuild the carb with a complete rebuild kit and then they went on the water (with my insistence). Their top mechanics stalled the engine and finally realized there was a way to restart it by cranking and "pumping`the gas.
So they brought back the machine to the shop, checked the whole fuel line, including gas pump, and they found absolutely nothing. They checked the plugs wires but aside from a bit of verdegris (copper oxidation) at the end of the wires, but nothing that can explain this. So tonight, we are at a complete loss (and they are the biggest BRP dealer in Canada).
I made a few phone calls of my own and was told to check the rotary valve timing (or something like that) and check if the pistons were not inverted in the rebuild process (by BRP). The pistons are OK, we checked them with a camera and saw the orientation arrows. They are now checking the rotary valve in case it was not put back together wrong.
They also suspect the rebuilt engine to be defective (taking some air from the crank?).
We have 10 days of summer weather left and after that, summer is gone and I am very frustrated at this, especially with all the money that I've thrown in on that issue (it now hurts).
Worse is that I can't sell a ski like that so I have to get to the bottom of it, no matter what.
Has anyone seen this? What should they check for in your opinion?
Thanks.
Benji.
