Hello Everyone, Need help to locate correct parts to replace exhaust riser (upside down U) from the manifold aft. My engine is a Universal M-18 on a 1985 Catalina 27. I remember reading somewhere an article possibly from the tech section of Mainsheet Magazine how to replace the parts but I can't locate the article I tore out and kept. Anyone else replace their exhaust lately? Thanks. Tim

M-18 Exhaust Riser
I did a rather lenghty article on the subject. I will try to reach you off line and send it to you.

Exhaust riser
I saw a post not long ago, I don't recall when, it may have been through the archives. Most are made with schedule 40 black pipe, most likely 1 1/4" which is about 1 5/8" od. Standard 45 and 90 elbows, straight pipe and maybe a union. I recall this one had a 1/8" x 1" strap welded to the riser for support and a union, from photos. Do an archive search and you should be able to find it. Not much too them.
