Pull Toy is living up to it's moniker. Got down to the ramp this evening, backed out of the dock and no forward thrust. Nice guy in a go-boat gave me a shove back to the dock :angry:
Got home and did some meter work, coils are all good, have power to blue when in reverse but no power to green in neutral. Forward is no power to either one which should be correct. These tests were done on the engine end connections while the knives were disconnected from the lower. Think the shift switch could be bad?? What other tests can I do to check the switch?

Hook up 12v to green wire direct from your bat and see if the prop locks. Do blue the same and be sure it's locking the other way. It being a '68, it should have a 3 wire push button switch.

Jim, it's a '67 lever type. Three wires. I disconnected the white plug from the shifter to run the meter there also. Red - 12 power, Grn - forward, Blu - reverse. Power is at the terminal and just as at the motor end had power to blue but nothing at green in neutral which leads me to believe the switch is bad. I'll pull the lever apart today and see what happened. It worked good last fall when it was put away so I'm thinking just some scummy corrosion at the contact(s). Here's an old picture of the unit many years ago before the rebuild.

Sorry Cal , for some reason I thought you had an Evinrude. Those Johnson switches are pricey.

Cal,

You have the wrong mindset about the system.
Reverse-power to blue
Neutral-no power
Forward-power to green
No power = no go.

The next generation with thru hub exhaust were as you were thinking. No power = forward.

Jim, you are absolutely correct!
I confused it with a hydro electric...
And now the good, bad, and embarrassing.
The good...I found the problem.
The bad...I tore apart the entire switch because it wasn't making contact. I did find that the contacts were sooted up from arching but that was easily cleaned up with some 2000 grit w/d. Put the entire switch together and redid the testing and still no forward.
And now the embarrassing...After taking everything apart, shifter, toggle, wiring, etc. I found that the MAIN black plug connector in the engine was not fully engaged and snapped together. After pushing the connector fully closed until it snapped everything worked as it should. AAAARGGGGGHHHHHH The old saying is just as good now as it always was.....if it doesn't work, check to make sure it's plugged in!
