1.6.3 Seakeeper Saddle Preparation
1) Ensure that screws fastening saddles to the installation fixture are tight (Fig 6).
2) Check that each saddle contains 2 plastic screws which will insure an adhesive gap of
.080” (2 mm) on top surface of hull as shown in Figure 11. Do not remove these screws.
3) Thoroughly clean with alcohol or acetone the inside surfaces of Seakeeper foundation
saddles to remove any contaminates as shown in Figure 11. Use new paper towels for
cleaning, not shop rags.
4)
Thoroughly sand all saddle inside surfaces with 80 grit sandpaper. (IMPORTANT
– BOND STRENGTH MAY BE REDUCED IF THIS STEP IS SKIPPED.)
5) Wipe surfaces clean from dust with alcohol or acetone using new paper towels, not shop
rags.
6) If using Plexus MA590 adhesive, apply Plexus PC-120 surface conditioner to inside
surfaces of Seakeeper foundation saddles in accordance with manufacturer instructions.
These instructions are located at the end of this section. If using an alternate adhesive,
check with manufacturer if any surface conditioner/etch is required for the aluminum
saddles.
