[. . . ] Never use wood since it will swell, possibly fracturing the plastic housing. Screw the hull nut in place being sure the notch on the upper rim of the housing and the corresponding arrow on the lip are still positioned forward toward the bow. (If your plastic housing has wrenching flats, do not clamp tightly, possibly causing the housing to fracture. ) Hand-tighten only. Remove any excess sealant on the outside of the hull to ensure smooth water flow over the paddlewheel. Warning: The O-rings must be intact and well lubricated to make a watertight seal. 6 2. 3. 4. 5. After the sealant cures, inspect the O-rings on the valve assembly (replace if necessary) and lubricate them with the silicone lubricant supplied (see Figure 3). 6. 8. Slide the valve assembly into the housing being sure to engage the key in the notch. 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. Slide the retaining pin through the valve assembly and paddlewheel insert. 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. Lead the wire in a counterclockwise direction and thread it through one eye in the cap nut. 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. When the boat is placed in the water, immediately check around the thru-hull sensor for leaks. It is best not to leave the boat in the water for more than 3 hours before checking it again. If there is a small leak, there may be considerable bilge water accumulation after 24 hour. [. . . ] Warning: Always use the cap nut and safety wire to secure the short emergency plug for a watertight seal. Clean, repair, or replace the valve assembly, so the flap valve moves freely and seats against the valve housing (see Figure 5). Warning: The O-rings must be intact and well lubricated to make a watertight seal. 3. 4. 11 To reinstall the valve assembly and paddlewheel insert, inspect (replace if necessary) and lubricate the O-rings on the valve assembly and the paddlewheel insert with silicone lubricant or petroleum jelly. Rapidly slide the valve assembly into the housing being sure to engage the key in the notch. [. . . ]
