I agree. I might have caused a high pressure event by raising the tongue of my trailer while the bottom of the lower unit was on the ground. I've noticed in similar threads that the engine had been stored/inactive for some time.
I have same problem with a 1979 Evinrude 115.
The defining symptom is that the 2 trim cylinders are extended and locked in that position.
The first photo shows the transom side of the assembly with 3 plugs removed. The plug at the right, below the motor, was under pressure. I had to use...
Sorry. It's not my boat, it's a neighbors. It is in the water now. The only purpose of my posts was to alert other having no-spark problems that the VRO could be the problem. My out-of-date manual shows that the VRO can do the same thing to the Power Pack as the Emergency shut-off switch...

Note on the wiring diagram:
This is in the Oil Injection System chapter
The simplified diagram only shows partial ground system elements
I was working on a neighbors engine that I was not familiar with. My terminology might not be correct.
There is plunger at the bottom, near the oil pickup that moves about 2 inches. There is no spark when the plunger is in the bottom position (and it is obvious where the contacts are)...
I have almost the same engine. My problem was the VRO float switch. The switch can ground out the power pac, just like the deadman switch. It appears to me that anything with a black/yellow wire is on the same ignition circuit.
