FORESPAR'S
® MARELON
® INTEGRATED PLUMBING SYSTEM
Exceeding ABYC recommendations and meeting all UL standards; its unique design provides easyinstallation in a wide variety of valve configurations. It allows the OEM to design systems neverbefore possible.All Marelon
® integrated
marine valves are sold as a complete system. The assembly consists of thru-
sailboat hull, valve body and tailpipe barb or female
pipe for boat thread end. The thru-hulls use a buttress style
thread for exceptional strength and are not compatible with any other valves. Thru-hulls cannot besold or used separately. All valves have one part number for the complete assembly. Each valve isfactory assembled and pressure tested. Forespar
® cannot be responsible for valves disassembledand modified or reassembled improperly.In
case for boats of an emergency, all non-screened thru-hull style valves are supplied with a handlecap/bung that is designed to plug the thru-hull from the outside. This plug can be put in placewhile the vessel is in the water. The valve can then be removed from the king-nut and any blockagecleared. 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 isneeded 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. Temperature Range -40 Ëš F to +176 Ëš F-40 Ëš C to +80 Ëš C Forespar
“ANTI-VENTURI T-HULL”
Custom tooled by Forespar
® , these new thru-hulls have been tested on boatsat varying rpm’s and turn rates up to 45 mph. On a 3/4”
generator for boat 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 for boats in the leading edge (photo #1-front) provides a
force-feed effect. To keep this force from overwhelming
marine equipment impellers,
the exit slot (photo #2-back) allows water flow to exit at a controlled rate.
