8 NAVMAN Fishfinder User ManualMountingOnce the best location of the transducer isdetermined, hold the transducer and bracketagainst the transom. The bottom surface of thetransducer needs to sit parallel to the surface ofthe water for the best signal return. The lowerface of the transducer should extend downbelow the bottom of the hull so that it will bebelow the surface of the water at high speeds.(See fig. 2.1)fig. 2.1MinimumimmersionrequiredMark the transom through the bracket slots tocorrectly place the two outer screws. Now drillthe two holes in the centre of the slots. This willallow you to adjust the transducer position lateron if required. Use two of the three stainlessscrews supplied to attach the bracket to thetransom. Ensure the lower face of the transduceris parallel with the ground (see fig. 3.1 and 3.2).Tighten the two screws.DEEP-“VEE”HULLFLAT-BOTTOMHULLfig. 3.1fig. 3.2Read this section carefully before attemptingthe transducer installation. Remember, thetransducer location is the most critical partof the installation. If this is not done properly,the transducer can’t perform at its designedpotential. Therefore the performance of thefishfinder, especially at higher speeds, will notbe satisfactory.• Transom Mount TransducerLocationThe transducer can be installed on any outboardor sterndrive powered boat. The transom mounttransducer has a safety “kick up” mountingbracket to help minimise damage to thetransducer should it impact the bottom or floatingdebris in the water.Select a position for the transducer that will:• allow the transducer a smooth flow ofwater over its surface at all times.• ensure a mount as deep in the water aspossible.• be clear of any interference from the trailerwhen launching or retrieving the boat.• be away from planing strakes or otherprojections from the hull that may causeaerated water to flow over the face of thetransducer.• be away from the propeller• be at least 150 mm ( 6" ) away from thekeel of the boat.Poor LocationPoor Angle Good Location and AngleGood LocationInstallation ñ The Transducer
