Re: 76 johnson 200 tilt trim help
Your factory power trim assembly was one of the very early trim systems. The motor was originally a 3-wire system. This older trim system uses a special control box which mounted separately under the splashwell of the boat. There was a single solenoid, fuse and two heavy cables which were wired direct to the battery-just like the engine. The down motion was wired direct through the trim switch on the control box handle. Since the up motion consumes so much current and will quickly burn up the handle trim switch, it is wired through the solenoid in that box, then through the trim switch. The inside cover of that box has a wiring diagram glued inside for reference. To test the motor, ground the black wire. If you touch the blue wire to the pos of the battery, the motor should go up. If you touch the green wire to the pos of the battery, the motor should go down. If for some reason you have a two wire motor, someone has updated the motor with one from a newer engine (mid year 1981 and later.) That model uses a control box which mounts on the back of the exhaust cover-yours will not have the mounting brackets for the box.
