Attach one pull ring to the paddlewheel insert (see Figure 5). Similarly, attach a pull ring to the blanking plug. Inspect the O-rings on the paddlewheel insert (replace if necessary) and lubricate them with the silicone lubricant supplied. 9. 10. Slide the paddlewheel insert into the housing with the arrows on the top pointing forward toward the bow. Seat it into place with a pushing twisting motion until the keys fit into the notches. The arrows on the top of the insert, the notch in the housing, and the arrow on the lip will be aligned. Be careful not to rotate the housing and disturb the sealant. Attach one safety ring to one end of the retaining pin. Slide the retaining pin through the valve assembly and paddlewheel insert. Attach the second safety ring to the retaining pin (see Figure 2). Warning: Always attach the safety wire to prevent 7 the insert from backing out in the unlikely event that the cap nut fails or is screwed on incorrectly. Attach the safety wire to one eye in the hull nut. Thread the short emergency plug onto the wire. Lead the wire in a counterclockwise direction and thread it through one eye in the cap nut. Thread the wire through the eye a second time. Then lead the wire through the pull ring and the second eye in the cap nut. Route the cable to the instrument being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the sensor cable from other electrical wiring and the engine. Coil any excess cable and secure it in place with zip-ties to prevent damage. Refer to the instrument owner's manual to connect the sensor to the instrument. 2. 3 Checking for Leaks Warning: Never install a thru-hull sensor and leave the boat in the water unchecked for several days. [. . . ] `Inspect (replace if necessary) and lubricate the O-ring with silicone lubricant or petroleum jelly (Vaseline ® ). WARNING: When the valve assembly is removed, always insert the short emergency plug with the cap nut and safety wire for a watertight seal. With the short emergency plug ready in one hand, remove the paddlewheel insert and valve assembly as one unit by pulling upward on the pull ring. Rapidly insert the short emergency plug to minimize the flow of water into the boat. [. . . ]
