When the engine starts, there is a voltage drop as the starters crank, followed by a power surge as the alternators kick in and the voltage comes back up.
Ferrites are only there to prevent RF (Radio Wave) interference from other onboard devices.
You should either:
-add an isolated battery to the boat to service only your electronics. That way it is unaffected by the starters.
-There are several devices on the market like Newmar Power's "Start-Gurad" that automatically switch electronics to backup power during engine start. They work great and the electronics don't skip a beat.

Testimonial: "I have return my A65 to the retailer/maintenance desk and they are in the process of repairing it. The idea they had was as you say a broken circuit. "

Depending on your transducer type, you may have a liquid filled type that simply needs refilling. If this is the case check for leaks and get it redone. If not it could be transducer placement or cavitation under the hull.
