Hi,<br /><br /> There is a motor for sale here locally that I have not seen in person yet. It is a 1969 Evinrude 115 HP. It has an electric shift. Can someone explain the pros and cons of this setup?<br /><br />Thanks,<br /><br />Shane

Re: Electric Shift

Turtle.... the 1969 115 has a "Hydro Electric Shift" setup as follows.<br /><br />(Hydro Electric Shift)<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.

Never mind about the question I asked. I just did a search for "electric shift" and that told me more than I needed to know :eek: <br /><br />Shane

Re: Electric Shift

Thanks Joe for all the information. It sounds great in theory but from all that I read from doing a search, it seems they caused lots of problems.<br /><br />Shane
