We have a 1991 Johnson 70 VRO. It is mint condition, cleaner on the inside than the outside. Low hours. Yesterday while we were skiing I pulled a hard left over choppy water, and attempted to adjust the trim while doing so. I noticed then that the UP buttons on both the control box and motor no longer worked when they worked about 2 minutes ago. The DOWN buttons simply makes the hydraulic pump run, but otherwise does nothing; the motor is all the way down. The trim gauge reflects this.<br /><br />Is this an electric or hydraulic problem? Fuse, short, rotten wires?<br /><br />The battery has a good charge, although shorty before attempting to trim the boat again we used the cigarette lighter about 10 times to stop the waterskiing rope from fraying. In the 2 minute time frame that it stopped working in, we also switched gas tanks.<br /><br />Any ideas?<br /><br />Best regards,<br /><br />Dylan
