4. Fillthe hull with enough water to submergethe transducer body.Use a
sand-filledbagor other heavyobject to hold the transducerin position.The
transducercannottransmit throughair, and the water purgesany air from
between thetransducer and the hull, and fills anyvoids in the coarse
fiberglasssurface.
5. View the sonarsignal on the display and compare againstwhat was
observedin Step 2, makingsure that the boat is inthe same location as it
wasduringyour observationsin Step 2. If the resultsare comparable,move
onto Step 6. Otherwise,locatea new positionin the hull and repeatSteps
3through 5.
6. Run the boat atvarious speeds and water depths whileobserving the
screenon the depth sounder. If depth performanceis required, testthe
transducerinwater at thedesired depth. Iftheperformanceis acceptable,
moveon to Step 7. If the performance isnot acceptable, repeat Steps3
through6.
7. Once youhave determined the best mountinglocation using the above
steps,mark the positionof the transducer.
3. Routing the Cable1. Once the mounting locationis determined and you have marked the
positionofthe transducer,route the cablefrom the transducerto the depth
sounder.
CAUTION!Do not cut or shorten the transducer cable, and try not to damage the
cable insulation. Route the cable as far as possible from anyVHF radio antenna
cablesor tachometer cables to reduce the possibility of interference. If the cable is
tooshort, extension cables are available to extend the transducer cable up to a total
of 50' (15 m). For assistance, conta ct the Customer Resource Center at
