Re: 72 johnson 100HP pops out of gear
Markdclay.... Yes, the default is for the unit to be engaged in forward gear (no voltage to either solenoid).<br /><br />That unit demands "Premium Blend" gear lube, also known as "Type C". Anything other than this will cause erratic problems, possibly what you're encountering.<br /><br />Other than that, for the unit to disengage forward gear to neutral and stay in neutral, I would also have to assume that somehow 12 volts is accidently being applied to the green (neutral) shift wire.<br /><br />After you shut the engine down, does the unit then go back into forward? If so, temporarily disconnect the green and blue wires leading to the lower unit, then water test it.<br /><br />If the problem still exists, I'd suspect the gearlube. If the problem no longer exists, then I'd lean towards an electrical short that's applying voltage to the green wire.<br /><br />Let us know what you find.
