Catalina 30 exhaust
Jody; I used to have a Catalina 30 with the Univ. 5411 diesel and had to replace the exhaust when it corroded through. The main pieces are inch and a quarter black iron elbows and nipples, available at any hardware store. Try to salvage the two pieces at the ends, the threaded piece that bolts to the exhaust manifold and the piece of threaded brass pipe with the water injection nipple brazed into it. Assemble loosely, fit into place and tighten as much as you can. Some people like to use a putty, some say it will harden into useless dreck. Any loose fittings will self-seal with soot from the inside after a few hours of running time. Wrap with fiberglass insulation, tuck the end under and trim. Use rubber gloves and long sleeves, fiberglass itches! Total cost about 15 bucks.
