Section 1: MECHANICAL INSTALLATION
1.5.2 Transfer of Holes to Foundation
1) Lower assembled fixture onto hull
structure.
2)
The four areas where the isolation
mounts will rest should be coplanar to
within 1/8” (3 mm). See Figure 9.
Do not
use the fixture to check co-planarity as it is
not stiff enough.
3) Align fixture in desired location and
transfer holes from fixture plate to the hull
structure. A transfer punch is
recommended for this step. Note that
holes in fixture plate are ø.257 (6.5 mm).
4) Remove fixture and drill holes in foundation
at marked locations to mate with holes in
Seakeeper isolation mounts. A ø.689
”
(17.5 mm) hole is recommended for
through-bolt installations.
NOTE: Certain foundation designs that
employ threaded blind holes in thick
plates may require the installer to obtain
alternate fasteners. Reference blind-hole
kit drawing 90614.
