Jim, John, etc; Thanks for the replies.. I think I'm going to swap out my old "vernalift" wet muffler to a 2" model, and then add a 2 to 1.5 reducer on the exhaust hose to the thru-hull. I'll get the model numbers and share. Any of the 34' owners who have pics of their 3GM30 mounted I would love to see them. I am in the process of building the mock engine to figure out fit on existing bed rails, etc;

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;
