Plastic hose goes from exhaust manifold to shaft log. Provides cooling water
to log. Hose retained at both ends with hose clamps. There is another yellow
collar at each end of this hose where it attaches to the manifold and where it
attaches to the log. What is this fitting and how is the hose disconnected
after loosening the hose clamps? Anyone familiar with this setup? Bob Siegel

This sounds to me like a press-fit fitting. They are like hose barbs
but much tighter fitting. (And much more difficult to push the hose
onto.) The yellow plastic ring shows how far on the hose should be
pushed. These fittings don't need clamps.
I'd cut the hose back the length of the fitting with a sharp blade to
remove it.
If you then square it off you should be able to re-use it, if its in
good condition.

Short answer: Maybe.

Long answer: The approval is based on a hose "system" (hose + connectors). If
you take a close look at the spec sheets of CG approved hose, you will
usually find some small print stating that the hose is only CG approved when
used with the approved connectors, and giving you a list of which connectors
are approved.

Based on a long ago article by Steve D'A in Passagemaker, I would add
that they are recommended by the manufacturer to use without hose
clamps only on hose specifically designed by the manufacturer for that
purpose. It was an article on fuel lines and there were no hoses made
that were coast guard approved for fuel use that were approved for use
without a hose clamp. He claimed that the manufacturer (Parker if I
remember correctly) recommended using hose clamps with other hoses.
Personally I would always use a hose clamp for any connection. Yes,
too lazy to look the reference up. -drew

I am now doing some fuel line replumbing and when talking to the shop they
offered those fittings but when I asked for the marine hose they said the
fittings were not compatible. Now back to standard hose barbs and swaged
crimps or hose clamps.

When reading the ABYC standards I was surprised to see that if using hose
clamps they are required they be reusable.
