I have a Yamaha XL1200 jet ski and have had a Lowrance Hook 3 installed on it. The finder has been replaced several times because of inteference.
To check the source of interference I have removed the wiring and left only the transducer mounted on the outside of the hull with the cable exiting the ski at the rear hatch. When the ski engine is not running the screen is clear (even though the transducer is in air) but the moment the engine is started the screen shows lots of rubbish. I have powered up the installation with a bench power supply totally separate from the ski battery and moved as far away from the ski as the cables will allow but I get the same result.
As there is only about 2 foot of transducer cable in the ski and its away from power cables etc I am at a loss as what can be causing the interference. Anyone have any ideas?
The attached pic shows from the center to the left without the engine running and from the the center to the right with the engine running.
