Hey all I'm new to the forums so thanks for having me got a question, just bought a 785 that has a exhaust leak. While doing the exhaust gasket I have noticed the water lines that run from the block and then from the front of the exhaust pipes to the exit nozzles have this sticky blue stuff on them, any idea what that is. Is it a good idea to just run all new lines since I have the whole exhaust out of the ski. Any info and tips on the reinstall would be great I'm a mechanic but first time working on a ski
