Jim,
In my 1978 C27 # 3692 I have 3 or 4 inch hose ( like for a clothes dryer
vent ) attached to the in and out vents at
the port and starboard corners of the stern to ventilate the engine cave.
Also has a blower connected, The hoses lay
on the hull floor. I have the ends secured to stay away from the prop shaft.

Subject: catalina27-talk: Vent Hose
I had a strange incident over the weekend. We were pulling into a marina
20
miles south of our home port and the engine started to vibrate abnormally.
We were in a very narrow area with rocks on both sides, so we could not
stop
for a diagnosis just then. We slowed down to idle and the vibration
stopped
after a few minutes, and we docked without incident. I thought the prop
had
caught something in the water, but it turned out that a bolt on the prop
shaft above the stuffing box inside the boat had caught on a flexible hose
and wound the wire frame from it around the stuffing box. It took the
better part of an hour to get it all untangled (My ribs and shoulder still
hurt from lying in the berth with my arm down into the engine
compartment!).
I evidently lost several feet of the hose before the wire broke, stopping
the vibration.
The hose seems to lead from a forward facing vent in the back corner of
the
boat on the starboard side. It comes through the cabin on the wall of the
starboard rear berth, then into the engine compartment. I can't remember
now if it was just lying in the engine compartment or if it was actually
connected to something. The bilge blower hose is next to it, so it is not
that one. I don't see anything obvious that it would connect to, but want
to be sure I am not creating a hazard of some sort. The boat is a 1979
traditional layout with the Atomic 4 if it makes a difference.
Thanks!
