the Garboard deck drain is to prevent the accumulation of water in the boat
while on the trailer during storage.
the older boats have a scoop on the underside of the hull that sets up the Venturi Siphon
if the plug is removed while the boat is underway - thus sucking out any water.
for newer boats that uses the aftermarket Garboard Drain, there is little to no
Venturi effect - - - this is where your electric bilge pump comes into play.
Older aluminum boats have the factory installed "scoop" for the drain system.
if you wanted to keep the drain in the bottom of the transom, then you must build
a new drain tube designed for the rubber plug so it will drain while the boat is underway.
but this will allow water to drain through gravity - not siphon. So the correct speed is a factor.
but this system is very inconvenient if not impossible to use while underway is that the
rubber plug is on the OUTSIDE of the boat . . . unless you have Orangutan arms,
it is very hard (and dangerous) to use this setup to drain water while under way ..... thus, the electric bilge pump.
and while on the topic of drain plugs . . . everything in the world has its pros and cons.
things that go on a boat is no exception. the twist-type stopper is for a boat drain.
the "flip style" plug should be reserved for champagne bottles,
bait tanks, beer coolers, kiddy pools, etc. not for a boat's main drain system.
this is highly debatable and strictly your choice.....
"your boat = your call".
