FWIW, from the West Marine catalog "The West Advisor":
"One other note of caution: For safety reasons, we don't recommend
safety seacocks for emergency dewatering because-if done improperly-
it may disable the engine when it is most needed. This process would
require shutting the sea cock valve and pulling the quick release plug
so the engine takes water from the flooded bilge for cooling, instead
of outside water. A far better solution is an electrically-clutched PTO
pump from Jabsco, multiple high capacity centrifugal bilge pumps, or
a driveshaft mounted pump like those from Erickson."
This is from the Master Catalog on p. 547 just below the Groco
Safety Seacock Conversion kit. I wonder how many of those they
sell?

An interesting addition to this is that one of my customers was dinged
by the surveyor about just such a seacock. It was listed under the
"Recommendations" category to remove it. He was required to satisfy all
recommendations by the insurance company.
The surveyors reasoning, spoken to the owner, not written, was exactly
what WM states in their catalog. That it is too easy for an
inexperienced person, or a short handed crew, to disable the engine,
thus complicating an already bad situation.
I don't know if it is just a pet peeve of that particular surveyor, or
if this is a coming trend. It would be interesting to see what would
happen if such a surveyor did a survey on a fairly new Cabo.
Speaking of Cabos, I was looking one over at the recent San Diego boat
show. I got to talking to the sales person and one of the topics was the
emergency bilge pumping seacock setup. His comments was that most
customers either don't know what it is or where it is, and those that do
probably wouldn't use it properly in an emergency if they had to. Not a
very positive view of the customers of what is supposed to be a top line
sportfisher.
