Well I picked up a new 89 XP LTD.(New to me) Started and ran great at the lake today. Being the first time at the lake with ski, I did some quick blast across the lake and open up the hood to check it out. It was filled with a white like smoke. It did not have a real smell to it. All most look like it was coming from the back cover under seat. Did not do any thing to suck up water inside, I just did a fast blast across the lake. Hoses,exhaust looked good. Did not see any oil or Fuel leaks. Not sure what would be making the smoke. Rear drive shaft was real warm to touch not sure if it should get that warm. I know there is not much to go on. But does anyone have an idea what this could be?
