Subject: Essentials of a Marine Boat Alarm System
From: (Rick Curtis)

I have a lot of
earned faith and respect for the folks at Marine Marketing.

I'm not surprised you have faith, after all your entire post is an advert
for the company you work for.
In other words it's SPAM, SPAM and nothing but SPAM.

Boats sinking because a hose failed whilst at the dock, wouldn't happen if
the owner closed the sea cocks.
My boat is never left without me first closing all sea cocks, which includes
the 3" at the exhaust outlet.

Jeeze, sounds like a poor design. My exhaust outlet is a foot out of the
water then the hose is routed up under the gunwale to provide a trap. The
deck would have to be awash before water got past it and then where would it
go? Back thru the engine cooling system to a seacock that is below water
but kept closed unless the motor is running?
