Re: Newer to Boating, have motor question
Though there may be an oportunity to get a parts motor. It is the exact same model, year, and size 1972 50hp. The owner says it runs but will not go into reverse. How big of a problem is this on an electric shift motor. And what would be a reasonable price for the motor.
Have you verified that your own lower will shift? That motor shifts with two solenoids in the leg. The solenoids don't actually do the shifting, rather they change oil pressure in passages in the lower unit that will cause the mechanism to shift. the basic pattern is:
0 volts on both blue and green wire = Forward gear (default)
12 Volts on Green only = Neutral
12 Volts on Green AND Blue = Reverse
You can test to see if the solenoids are working at least by applying voltages to the wires. Put 12 V on each of the wires, and listen for the clicks similar to the click you get when you engage the choke solenoid. To actually see if the motor is shifting, the motor needs to be turning. Do a search for Joe Reeves testing procedure for hydro-electric shift to get a better idea of how to do that.
With reference to the above motor, if its not going into reverse but IS going into neutral, there may be a problem with one of the solenoids (specifically the one attached to the blue wire). While having a second motor as a parts cache is never a bad idea, I'd make sure that your shifting mechanism is working before buying another non-functional motor.
