Our 34 came OEM with a 3GM30. Still running strong after all these years J The exhaust from engine to muffler is 2 inch. From muffler to transom is 1.5 inch. We just this year replaced the original stainless muffler which was leaking with a fiberglass model from Centek. Was a direct replacement no modifications needed Cheers John and Maryann Legacy III 1982 C&C 34 Noank, CT From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of conner.s...@comcast.net Sent: Sunday, April 13, 2014 1:47 PM To: cnc-list@cnc-list.com Subject: Stus-List 3GM30F exhaust specs... I'm in the process of swapping out and old 2QM20H (still running strong--just had the chance to acquire an GM) with a 3GM30F. The 3GM has 2" exhaust which I assume is OEM specs (none of the manuals specify exactly). But I was thinking I could adapt to my existing 1.5" exhaust system and avoid the hassle of replacing wet muffler and 10' of hose.. I think I found a post or two where this was done.. does anyone have experience with this or strong caution against? Thanks ps. will try and post some specs on fit as I build the mock engine and figure out dimensions, etc; --- This email is free from viruses and malware because avast!
