User manual STANDARD HORIZON P58 INSTALL GUIDE

[. . . ] Apply marine sealant to the threads of two, #10 x 1-1/4", self-tapping bracket screws to prevent water seepage into the transom. Be sure the nuts are in the slots in the back of the bracket and any shim(s) is in place (see Figure 3). Do not tighten the screws completely at this time. nuts bracket recess (2) Caution: Do not position the bow of the multisensor lower than the stern because aeration will occur. 2. Using a straight edge, sight the underside of the multisensor relative to the underside of the hull (see Figure 5). [. . . ] This ensures that the paddlewheel will be in contact with the water at high speeds. · Stepped transom and jet boats (3° transom angle) --Use the 9° shim with the taper down. If your boat is capable of speeds above 20kn (28MPH), install the bracket with both the 9° and 4. 5° shims, taper down (see Figure 5). This ensures that the paddlewheel will be in contact with the water at high speeds. Install the 4. 5° shim against the transom after shaving the interfering portion of the rails and lower bump. · Small aluminum and fiberglass boats (20° transom angle)-- Use the 9° shim with the taper up. If your boat is capable of speeds above 20kn (28MPH), install the bracket with only the 4. 5° shim, taper up. · If you are unsure about using the shim(s), do one of below: · Measure the transom angle of your boat using a digital level or bubble level and protractor. · Experiment with the shims by following the instructions "Mounting & Adjusting". 2 AIRMAR cable cover ® cable clamp 50mm (2") parallel to waterline Hull projection 0­3mm (0­1/8") Figure 4.

If the performance improves while turning to the side on which the multisensor is installed, its position probably needs adjustment. To improve performance, try the following one at a time in the order given. Move the multisensor farther into the water in increments of 3mm (1/8") (see Figure 4). If a hole has been drilled in the transom, open the appropriate slot in the cable cover. At each of the marked locations, use a 3mm or 1/8" bit to drill a hole 10mm (3/8") deep. To prevent drilling too deeply, wrap masking tape around the bit 10mm (3/8") from the point. Apply marine sealant to the threads of the #6 x 1/2" self-tapping screws to prevent water from seeping into the transom. If you have drilled a hole through the transom, apply marine sealant to the space around the cable where it passes through the transom. 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(s). Coil any excess cable and secure it in place with zip-ties to prevent damage. [. . . ] Never install a multisensor and leave the boat in the water unchecked for several days. The paddlewheel must be oriented correctly to measure boat speed. AIRMAR ® Operation & Maintenance Releasing the Multisensor Caution: Never strike the multisensor with anything except the palm of the hand. Give a sharp blow to the bottom of the multisensor using the palm of the hand. BOW short side of paddlewheel blade Figure 8. Orienting the paddlewheel Antifouling Paint Aquatic growth can accumulate rapidly on the multisensor's surface reducing performance within weeks. Surfaces exposed to salt water that do not interlock, must be coated with anti-fouling paint. [. . . ]
