On my boat asm 2000 # 283 the intake side of the muffler is 90mm and
the exaust is 75mm. I tried to retrofit a vetus but I did not like
the way it fit into the engine room. The main problem was the intake
side only swiveled to 90 degrees. I ordered a replacement from
Amel. I am in New Zealand so the choices I had may not be as good as
what you can get in Europe.
