Location: Cedarburg, Wisconsin | Yes, the motor could be in decline but so could the battery so have it load checked. I've had trolling motors where the seals leaked water into the armature and everything started rusting, but even then I didn't notice too much of a power loss.
First I'd check the connections to the battery. Are they perfectly clean, if not clean them up or replace them so a good battery can fully transfer its power.
Second, I'd check the inline fuse. Open it up and check for corrosion. if there is some, replace the holder and fuse.
Third, I'd check the hull. If it is dirty that could do it, possibly
Finally I'd have the motor speed control checked to make sure you are actually turning the motor full on. If the control part doesn't call for full speed the motor doesn't ever run to full capability.
If I had to make a prediction, I'd say the most likely cause is extra resistance in the wiring from corrosion or a bad battery. |
