HI, we are having an issue with 1972 65 HP Hyrdo shirft. we are able to jump it into neutral then hook up the wires that go to LU, it cranks in forward again.. so, for some reason the green wire is not getting 12v when hooked back up. It did work ok before we took off lower unit and replaced the impeller and cleaned it up. So now it's a bit frustrating that we are at this stage.. any ideas? BTW, the control unit (we have two for this) is in very good shape the the switch in this appears to be in good condition. I am thinking that may be the culprit. thanks for any advice. The motor is running GREAT and we wish to get this set up on a 1972 Starcraft Nova (same year boat & motor and cool set up).

and yes, we have correct oil in LU plenty of it. We believe it to be 100% electrical as when we jump the neutral or reverse the LU reacts properly. When we send 12v to green (neutral) it immediately goes to neutral.

thank for any assistance.


 
When in neutral and the key in the ON or START position, it comes across to me via your wording that you DO NOT have 12v at the Green wire at the engine where the wire connects to the lower unit.... Is that correct?.... If correct, check the green wire for voltage at the shift switch.

Let us know what you find.
