Installation of Thru Hull Fittings
Note: To ensure correct positioning of the thru hull fitting, consult with your local TARTAN
Dealer.
Installations in Non-Cored Areas:
A. Drill hole size to accommodate the thru hull fitting.
B. A small backup plate is required for strength purposes. Marine plywood is suitable. A hole the
same size as that in the hull should be drilled in the wood. The holes may then be aligned, and
the wooden backup plate may be bedded with marine sealer and allowed to dry.
C. Install the thru hull fitting, and securely tighten the nut.
Installations in Cored Areas:
A. Drill hole size to accommodate the thru hull fitting.
B. Using a knife, remove the synthetic core from the area surrounding the hole at least two inches
beyond the edge of the hole.
C. Fill this area with resin saturated fiberglass mat and let cure. The hole may have to be trimmed or
reshaped to accommodate the thru hull.
D. Mount the thru hull fitting with marine sealer on the flange portion of the fitting. A layer of
marine sealer should also be applied between the interior portion of the fitting and the hull.
Allow to dry.
Note: After applying the marine sealer between the exterior of the fitting and the hull, tighten the
nut. The thru hull fitting should not be allowed to turn as this may break the seal. A wrench to
tighten the nut and a wrench to hold the thru hull will be required.
