depth finder issue narrowed down - now what?

2011 Seadoo 230 SP
Issue: Depth finder no longer working

As soon as I start the port side engine the depth finder turns to all dashes.
When I shut the port side engine, the dashes turn back to the current depth.

It works fine with both motors turned off.
It works fine with just the starboard engine running.

Not sure what to try next...

Sounds like your getting a reversed polarity signal from your port engine. I would take the boat back to whomever you had install it and check out the wiring because it was done wrong!!

I bought it new from sea doo dealer. It used to work fine for the first 25 hours. Its a 230sp (came with it installed from the factory)
