Not motor but the batteries. I've had to keep the motor running because just the juice of the sonar after 10 minutes was making it hard to start the motor. Also noticed quite the power draw when recharging the batteries after each trip so I know it's time to upgrade.
Usually, I just buy batteries at Walmart and swap them out every 4 years, but there are a lot of new options as of late. Guys at DCB Battery in El Cajon answered every question I had and thankfully, because I probably saved $600 for not swapping out to some other types of batteries..
What a pain in the ass swapping out 56# batteries through a tiny hole in the most uncomfortable positions. Then, I had to make sure every wire went where they supposed to. I thankfully got a quick lesson on making two 12v into a 24v for my trolling motor.
My knees, shoulders, biceps, back, and legs all hurt after this one!
Mission accomplished, but the motor wouldn't start, so back in to look for the missing wire!
Found it and the motor popped right on!
Now to test it out at some point to make sure everything is working properly. At least my meter is saying everything is getting the power it supposed to have, so that's a start.
