I have a 30' hunter and the exhaust muffler is lying unlevel to the water line. It lies on a 30 deg angle down towards the stern. The unit is a large blue cylinder with a hose connectio at each end. It seem as if there is a perfect spot for the muffler to lay down in if the hose from the mixing elbow to the muffler were maybe a foot longer. Does anyone know where to get a replacement muffler, a company name, or flushing instructions? At high rpms my engine steams a bit out the exhaust. I'm thinking it might be improper mixing or a shortage of raw water due to the 30 deg angle of the muffler.
