I have a 1970 Evinrude Triumph 60 hp with the hydro electric shifter. Forward and reverse work but no neutral. Both solenoids ohmeter ok and the valve actuator rods are adjusted per the manual. Any ideas out there?

Could be a problem with the shifter switch. If I'm not mistaken, neutral involves powering both wires. If there's a problem with your switch, that would do it.

I've got a similar problem with mine, 1969 85HP Johnson. Except that one of my shift solenoids does have a short in it and it's blowing out the blocking diode. You might check that. Mines under the dash near the ignition switch.

I just read the reply from R. Johnson "Lieutenant" on how to bench test this unit. Thanks a million! I suspect I will be able to tweak the adjustments on the valve control rods from the solenoids and get this puppy working.

LRW....just so I understand...you have no neutral with the engine running....is that correct?<br /><br />The following was posted by Joe Reeves. Maybe it will help....maybe you already know the info contained but can't hurt.... :) <br /><br />The following will explain the shifting setup on your engine. Possibly you simply have the wrong gear lube in the lower unit.<br /><br />(Hydro Electric Shift)<br />(J. Reeves)<br /><br />The shifting setup of the lower unit is what's called a "Hydro Electric Shift", which is quite complex consisting of voltage being applied to solenoids in the lower unit which in turn change oil passages via a oil pump that supplies various pressure on a spring loaded shifter dog. The wires leading to the lower unit (at the powerhead) are "Green" and "Blue". The engine must be running or cranking over in order to shift out of forward gear.<br /><br />You CAN NOT use HI VIS lube in that lower unit. You MUST USE what OMC calls "Preminum Blend" lube, commonly called "Type C". (A thinner lube) <br /><br />In neutral, you need 12v to the "Green" wire. <br />In reverse, you need 12v to both wires, the "Green" one and the "Blue" one. <br />In forward, there should be no voltage to either wire. (The spring loaded shifter dog forces the unit into forward gear) <br /><br />To check the lower unit for proper shifting to make sure you have no trouble there, remove the spark plugs to avoid problems and to allow a higher cranking speed. <br /><br />This next step eliminates the actual shift switch in case problems may exist there.... Disconnect the blue & green wires at the knife connectors (the rubber insulated boots) leading to the lower unit at the powerhead, then using jumpers, take voltage direct from the starter solenoid to apply voltage to the "Green" wire for neutral, then both wires 'Green" & "Blue" for reverse (Remember the engine must be cranking over in order to shift).<br /><br />With no voltage applied, the unit should be in forward. No need for a ground jumper... the lower unit's already grounded. You may crank the engine with the key switch or by energizing the starter solenoid with a jumper wire.<br /><br />--------------------<br />Joe (30+ Years With OMC)
