[Rhodes22-list] Replacement Seat Drains

[brad haslett]

Joe,

My boat had the "nipples" replaced by a previous owner
with 3/4" plastic thru-hulls but one had cracked due
to weather so I replaced them with 1".  The oversized
drains carry a lot more water with less chance of
clogging with leaves, etc., but, there is a limit as
to how big you can go.  The larger the diameter flange
on the seat drains, the higher the water level must
get before it starts to drain.  Also, as Rummy pointed
out on an earlier post, the flange (exposed part) will
not fit in the seat drain channel and may have to be
ground down and caulked for a good fit.  The thru-hull
next to the motor mount (at least on mine) had to be
trimmed to make room for the starboard-most motor
rail. You will need a good wood bit for the size drain
you plan to install and some patience with the
drilling process so as not to remove any more
fiberglass than necessary for a clean hole with no
burrs.
