I'm sorry to hear that you are having trouble with your Motorguide Varimax Great White trolling motor. Here is a diagram of the upper control housing for the 2009 model that may be helpful:

1. Control housing assembly
2. Tilt tube assembly
3. Steering shaft assembly
4. Tension spring
5. Speed control knob
6. Directional indicator
7. Steering handle assembly

Regarding the issue with the motor only running in reverse, it is possible that there is a problem with the control housing assembly or the wiring connections to the motor. You may want to inspect the wiring and connections for any signs of damage or corrosion. If you are unable to identify the issue or make the necessary repairs, you may want to consider taking the trolling motor to a Motorguide service center for professional diagnosis and repair.

This is most often caused by a faulty 24 Volt, section, (usually damaged output semiconductors, or the drive?) in the speed controller, fault, the only "Fix" is replacement. Simply obtain the entire speed controller and replace it "En Bloc" as it were. You will need to also obtain a service manual so you can disassemble it and obtain the parts numbers for the replacement parts.Otherwise take it to a professional and ask for a "Quote" as to prospective costings and go from there.

put the motor in the water and ensure that the propeller is at the rear. On the head of the unit (where the direction indicator is) push down and turn the round plastic plate (this plate has the direction indicator on it) clockwise until the direction indicator mark (mine is blue and is about one inch long) is in line with the alignment bar on the non-moveable part on the head. You will hear several "clicks" and this means that the indicator plate is clicking around to the proper directional alignment with the motor in the water.

Trolling motor runs on it's own when plugged in,speed adjuster won't control speed and 3 position switch doesn't perform either..please help. motorguide 74lb thrust.

Make sure the oil is correct and nothingimpedes the cooling.

It very likely has a power transistor to vary the current to the motor. I am guessing that transistor has a collector to emitter short. That can be verified with a common ohm meter on a low ohms scale.
