I have the FSM for my 1997 XP and GTX's.  The instructions are pretty clear, but I do have a few questions.
1 - Why do you have to pinch off the engine drain hose?
2 - For the XP, they have you remove both hoses from the head. Why not just remove one (the inlet) and let the antifreeze flow through system.
3 - Could a guy just install a hose T with cap at the inlet on both machines, pinch off the engine drainhose and fill from there until it runs out the exhaust?
4 - The skiis are up at the cabin, but I want to do it next weekend I go up and have the supplies ready. Are the hoses to the head 1/2" or 5/8"
My local dealer says they just connect a hose and pump to the fitting at the back, start the skiis and run until antifreeze comes out the exhaust. Would this be a better way to do it? It'll get to -40° where they are stored over the winter, so I want to make sure it's done right.
They said if you dont run them, the cylinders can fill with water, but the FSM doesn't have you run it. I assume that is since you are isolating the engine and then doing the exhaust seperate. Would the water flow back through the exhaust ports?
