I have a 1986 Evinrude 175XP and the trim is not working properly. When I try to lower the motor from the full up position the trim arms lower before the motor reaches them, making the tilt arm the only thing controlling the motor's position. The trim arms do operate both up and down, but are out of position before the motor reaches them. Is this a bad sender or crossed wire? The fluid level is fine and was just topped off and bled over the weekend. Thanks in advance for any advice.
