So I pulled the cover off the boat and motor this weekend and hooked the battery up (which is showing to have a full charge). The motor was trimmed down over the winter so any condensation could drain. When I hit the button on the motor to trim it up, all i get is a hum but no movement. I tried trimming it down which does work but very slowly. I haven't ruled out the battery yet even though it's showing a full charge. Any suggestions on where to start with this issue?
