Yes its a 2000 GTI....damn my title has it listed as 2005.
So don't start mixing Apt-tc and marine grade 2 stroke.....If I did want to change oil any youtubes you can suggest???
Thanks
Yeah definitely do not mix the two. The 717 uses a rotary valve and cavity that is continually bathed in oil, so all that needs to be drained, as well as the oil tank itself and the lines that feed the rotary bath and the oil pump.
I would highly suggest changing out all the lines of the oil system with Tigon, but especially the little ones that go from the oil pump to the intake. The stock ones get old, brittle, crack and leak oil, robbing engine of lubrication. Would also suggest replacing the grey tempo fuel lines with black automotive fuel line. And if the ski still has those grey lines, rebuild the carb with OEM kit. Time consuming, but not difficult. Get a new oil filter as well. WSM makes one that works well and inexpensive. Just put with the arrow facing the right way.
I don't have any links to videos to changing the oil, but its not too difficult, honestly. What I would first do if the fat lines from the oil tank are stock, is get replacement line for both sizes, as well as the return. Let the ski sit overnight so all the oil drains to the bottom. Then get a container, cut the fatter line near the middle and drain the oil tank into this. Then although I am not usually an advocate, you can get an inexpensive brake bleeding tool from HarborFreight, attach to the large line going under the engine from the oil tank and suck/pump out the old oil. Do the same for the line feeding the oil pump.
Then cut and attach the new fat lines, both going under the engine and the oil pump, clamping with stainless worm clamps or Oetiker clamps. Put new oil filter on line that feeds oil pump. Also be sure to retain the stretched spiral inside the oil pump feed line and use in the new line. This is to keep the line from getting pinched or kinked and restricting flow. There is also an oil return line coming from under the exhaust manifold on backside that goes back to the top of the oil tank. It's an open loop system, so oil overflow from pressure can return to the oil tank.
Then fill the oil tank with some new oil, and work any bubbles out of the large lines by pinching. Then, if there is fuel in the fuel tank, need to add 2stroke oil to that to ensure engine is lubricated while bleeding oil lines. The amount will depend on the amount of fuel. Best to ride the ski before doing all this to get the fuel level low, then throw a few ounces of 2stroke in the tank.
But after changing the oil lines and filling tank partway with oil, start the engine on the trailer hooked to hose, and reach down under carb to pull back the oil lever mimicking WOT.... then watch the oil and air bubbles get pushed through the little lines. Once these are full and she is smoking a lot, you are golden. Fill the oil tank up most of the way and take to ramp, and run on trailer for a bit, looking for any leaks, etc.
