Long story short, I have a vetus waterlift muffler
with an output fitting of 45mm. My exhaust
hose at this point is 40mm. Is there an adapter that I can buy/make?
was run without intake water
. The exhaust
gas melted the old water lift muffler
input fitting and part of the hose that connects the engine elbow
to the water lift
muffler. Instead of trying to measure the ID of the hose (which was deformed from the heat), I measured the OD of the engine elbow
fitting and assumed they would be the same. I used the 45mm measurement to order new hose and a new waterlift muffler.
Today, I discovered that all my old exhaust hose is 40mm. My old vetus muffler had 40mm input and output fittings and the previous owner had forced a 40mm hose over the 45mm engine elbow.
So today, my system is 45mm elbow->45mm hose to muffler ->45mm input fitting at muffler ->45mm output fitting at muffler ->40mm hose to transom.
If no adapter exists, I plan to get a 40mm vetus muffler. It appears that the input fitting on vetus mufflers are interchangeable between (40,45, 51).
