Recently i was given a 2002 Xpress bass boat w/ a 115 yamaha. The speedometer and the depth/fishfinder are the only two things that do not work. Any ideas on how these two are related (since they went out at the same time?)
Im guessing that they share a fuse which may have blown or have a common grounding issue?
I know about the hole on the bottom on the motor can get clogged and will prevent the speedo from working but that would not explain the depth finder issues.
