Re: crack in exhaust bridge

Hey Gary...are you talking about the partion between exhaust holes in the cylinder? If so, is the crack just in the sleeve or is the aluminum cracked also. My 86' 90hp Rude has a crack in the sleeve in the above place. Chamfered it so the rings won't catch. Been running for a year or so. No problem. If the aluminum is cracked, my be best to have it sleeved. Ash your local dealer about resleeving. They may be able to put on to someone local.
