an you imagine the safety issues
with a dry exhaust system on a pleasure craft ..

The first time I ever fished offshore in Hatteras (circa 1964?) we went out
with Cap'n Eif O'Neil in a 3x' boat with a centrally mounted V-8 and vertical
stacks like you see on a truck, with , dare I say it, asbestos sleeves on them.

40 years of debauchery later and I am still alive!

It was loud like a Harley but not oppressive.
