Today after backing out the boat it stalled. I tried starting the boat, after putting it in neutral, and it would not start. I trimmed the motor all the way down, as it was up slightly. Again it would not start, or now trim. The throttle seemed to be sticking, or was hard to move. It seemed like the throttle was stuck in gear so it wouldn't start. I tried moving the throttle, but it was difficult to put it in reverse. I tried jumping the battery, but it wouldn't start. I took out the battery to change it and it is charged. I think the throttle is misaligned. Any suggestion on how to address this without bringing it to the marina?
