O-RING
• Remove the previously applied adhesive protectors from the counter flange.
• Verify that the O-ring seat is well cleaned and has not been damaged during installation.
• Position the O-ring correctly on the counter flange (ref. 14A), assemble the retractable
thruster (fig.14), spread marine grease on the bolt threads (ref. 14B) and fix securely with
the supplied screws.
The counter flange screws should be tightened to 15Nm, tightening little by little
in a cross pattern as in the example in figure 15.
WARNING: after about a week from installation, check the correct tightening of
the screws to compensate for any settling of the O-ring.
