MARELON
®
INTEGRATED PLUMBING SYSTEM
Exceeding ABYC recommendations and meeting all UL standards; its unique design
provides easy installation in a wide variety of valve configurations. It allows the OEM
to design systems never before possible.
All Marelon
®
integrated valves are sold as a complete system. The assembly
consists of thru-hull, valve body and tailpipe barb or female pipe thread end.
The thru-hulls use a buttress style thread for exceptional strength and are not
compatible with any other valves. Thru-hulls cannot be sold or used separately.
All valves have one part number for the complete assembly. Each valve is factory
assembled and pressure tested. Forespar
®
cannot be responsible for valves
disassembled and modified or reassembled improperly.
In case of an emergency, all non-screened thru-hull style valves are supplied with a handle
cap/bung that is designed to plug the thru-hull from the outside. This plug can be put in
place while the vessel is in the water. The valve can then be removed from the king-nut and
any blockage cleared. Warning – Never leave a boat unattended while bung is in place and
valve is disassembled. This bung plug is for temporary use only. The bung can also be used
during Winter storage to keep debris from collecting or insects from nesting inside thru-hull.
Per ABYC/UL requirements, a flat surface approximately the same diameter as the king-nut
is needed inside the hull for proper installation. All valves are full port. The I.D. of the hose
barb is carried thru the ball so there is no restriction of flow.

LOCKING HANDLE OPTION
Locking handle option for
integrated Seacocks 1”(25.4mm)
through 2”(50.8mm) sizes
Forespar offers an optional locking
plate installed at the factory on any
“93” series Integrated Seacocks.
These new locking plates allow
the handle to be set in the closed
position and a pad-lock used to
positively lock the valve closed. This new feature will satisfy
the USCG requirements for locking overboard discharged head
system seacocks in the closed, no discharge position.
ANTI-VENTURI T-HULL
Custom tooled by Forespar
®
, these new thru-hulls have been tested on boats at varying
rpm’s and turn rates up to 45 mph. On a 3/4” generator intake line with this thru hull
fitted, 0” to ~5” of vacuum was noted. This did not present a pressure situation which
could potentially push water past the vanes of an older impeller and flood the cylinders
or starve it of cooling water. The unique notch and lowered ramp in the leading edge
(photo #1-front) provides a force-feed effect. To keep this force from overwhelming
equipment impellers, the exit slot (photo #2-back) allows water flow to exit at a
controlled rate. Installed and tested by the Monterey Boats team of engineers.
The new Forespar

ENGINE FLUSH OUT VALVE
Engines running in salt or brackish water
need to be flushed with fresh water after use
to prevent costly corrosion during Winter or
off-season storage. Forespar
®
has designed
a single valve system that makes this
maintenance procedure simple.
This Seacock/Y Valve configuration includes
a brass garden hose connection to facilitate
regular fresh water engine flushing valve includes thru-hull that
must be used. A quick and easy way to flush inboard engine
systems... an often difficult maintenance task.
