Adapting 1 15/16" muffler connect to 1 5/8" exhaust hose 1988 Universal M25XP

[jlwoodard]

Anybody have experience adapting 2" water muffler to 1 5/8" exhaust hose?  Putting new muffler on, same as old; however, the hose is not going to go back on and I am hoping to find a work around without having to replace the entire hose length.

What muffler did you buy with a 2" hose outlet? You may also have issues at the thru-hull end as well.

A Vetus 50R, exact same that was on there.  Technically the hose connect are 1 15/16".

It would help if you listed your boat's specifics (year hull, engine, etc.) on your signature line to help folks better target responses to your questions.

But I think you may be mixing up ID and OD sizes.  Check carefully.

Yeah about a dozen times at last count.

I recommend a Centek Vernatube 2" x 1-5/8" reducer, which is what I had Bill use when "we" did his 2" muffler.  You can see here where he reduced it down under the sink:

It's a one-off size not a fitzall.
