I have a custom made boat, River Wild. When I ordered the boat I want dual batteries, up front..for weight distribution.

The problem from the "get go", if I start the motor either my ETech 105 or my Yamaha 8 and the depth finder is on....motor starts but depth finder goes blank.

I had 2 marine batteries, size 24, just replaced the 24's with 2 marine size 31. I thought the bigger batteries would eliminate the problem...
played in the Chehalis today....same problem.

I have gotten good at re-starting the depth finder but would prefer not to have to do that....

Looking for a possible solution?????


Oh, I do have a perko switch, doesn't matter if on 1, 2, or All
