2.5.4 Seakeeper Saddle Preparation

1. Ensure that screws fastening saddles to the installation fixture are tight (Figure 13).
2. Check that each saddle contains 2 plastic screws which will ensure an adhesive gap of .080 in. (2 mm) on top surface of hull as shown in Figure 18.

3. Thoroughly sand all saddle inside surfaces with 80 grit sandpaper. (IMPORTANT – BOND STRENGTH MAY
BE REDUCED IF THIS STEP IS SKIPPED.)

4. Wipe surfaces clean from dust with alcohol or acetone using new paper towels, not shop rags.

5. 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.
