New to seadoo pwc. I have 2004 GTI LE. Bought several months ago,started ,sounded good. It sat through winter. Went outlast week and was going to start, found water in cylinders. Removed plugs,blew out water. Have not tried to start again,yet. Never had it in the water. What could have caused water to get in engine??? Any advice would be greatly appreciated. I have since learned that it probably froze causing some damage. Not for sure. What should I look for?? HELP!!!!! Thanks
