Hey all,
I have a 1971 Evinrude Lark 50hp.
I got it with a boat I bought, the guy who sold it to me told me that the engine was scrap! as he could never get it to start.
I could not get the engine running either but i noticed that it had excellent compression so I decided to try again.
I got the old service manual for it and went through the wiring diagram. I noticed that one of the Posative terminals from the starter solenoid was connected to the engine (grounded), I put it onto the starter solenoid and the electrics on the engine came to life!
I changed the plugs, lines, gear oil(I used standard gear oil), checked impeller etc.... hooked her up to a battery and she started up first turn!
The only problem I had was that the engine was stuck in forward gear, I checked the shift solenoids in the gearbox and noticed that the connections were submersed in gear oil, so I put new connectors on the wires and covered them in oil-proof tape. I put the whole thing back together using a small gasket that I made from gasket paper (was thicker than original gasket).
Started her up but still no shifting. checked the shift wires and noticed that the green wire was not getting any power because it was disconnected at the connecter beside the starter solenoid (wire had worn off the connecter) I reconnected the green wire and started her up....
NOW she was still in forward, i tried neutral and still nothing, BUT when I tried the reverse button the prop snapped into reverse. I tried neutral again and she snapped back into forward gear. (Why the F**K would she not go into neutral??)
I asked a few guys and they told me to get the correct type C oil for the Gearbox. After a long time and a lot of bother and money, I got 2 litres of the stuff that a dealer had laying around for the past 20-30 years.
I changed the oil in the Gear Case to the OMC Premium blend. I started up the engine, and...... It was still stuck in forward gear. I tried neutral but still nothing. i tried reverse and instead of snapping into reverse, it stopped for about a second and then started spinning a bit in reverse, then stopped for a bit then started spinning slowly then stopped again then started spinning again and kept doing this.... I then put her into neutral and the F***ing thing went into forward gear again! HOLY F**K, I am seriously frustrated at this point!
I checked to see if there was enough oil in the Gearcase and there was.
I tried the voltage going to the shift wires and the green wire was reading 9.4v when in neutral, the blue was reading 11.2v and green reading 9.4v when in reverse. ( also if i leave the key switched on for a while with the neutral button pressed in the green wire heats up!)
I tried taking a 12v jumper wire from the battery directly to the green wire, when I read the wire before i connect it it reads 12v, when I connect it to the green wire it reads 9.4v like before.
when I connect the green and blue to 12v jumper wires, the blue reads 11.2v like before.
Can anyone help me?????? I dont know what to do next???
