AP/MFD Interference

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum MAK1377,

It is indeed possible that the noise from the pump's power leads may indeed be causing interference visible within the fishfinder's imagery. Generally, it is advised that transducer cables not be bundled with or routed in close proximity to other cables. Before re-routing the transducer cable, you may want to consider installing as many as six ferrite bead RF Chokes as close as is permissible to each end of the pump's power leads to correct the problem.
