Curious to see what experiences others have had with these units. I'm having BIG TIME trouble with mine in a '72 65hp Johnson.
The motor is locked in forward, which obviously prevents shifting, but also won't allow for me to start the motor. Problems arose when the previous owner put 80-90W gear lube in instead of the OMC stuff. I know it's a complicated unit and would love to toss it, but then I either pay for school or a "new" motor. Also love to get it fixed because it's going to keep me off the water for opener, and I don't know how much longer I can wait.:(

If anyone has ANY input of ANY kind, I'd love to hear it.

The spring loaded shift dog goes into forward when not forced into neutral by the oil pump. The engine actually starts in forward-for a brief moment- before it shifts into neutral. Prop turns maybe a third of a turn before it stops. The shift solenoids are no longer available from Bombardier. A test of the wires and solenoids needs to be done to see works and what doesn't . The Johnson shift switch in the remote control box is available if needed-pricey though. As with anything nearly 35 years old, condition if the wires in the harness should be checked. There are a lot of these 3 cylinders engines in the non-electric shift area, 1973 and up that can be had fairly cheap. I would get a newer unit before putting too much $$$'s in yours. Models above 1984 are prop shaft rated and offer a little more go than the crankshaft rated models prior to '84. If you are determined to keep the '72 at all costs, buy a service manual for it +-$35.00 and locate all the junk yard dealers in you area.
