    It's not suppose to rachet in reverse. Going to get it ack together and tank test it.

    2 vent plugs?

    Maybe I misread some of the posts but after removing the prop shaft assembly and simulating a shift into reverse by pushing in the plunger, it is hard to believe there is enough spring left to allow the clutch to push back against it to clear the reverse gear. The plunger in the picture is...

    2 vent plugs?

    Guess the question I need to answer is what is keeping the clutch from backing off the reverse gear. Something with the spring? Nothing appeared to be physically damaged. Don't know how it could be the shift wedge. Wish I knew how it was reacting before I disassembled it but I wonder now...

    No shift fork in this 40, it has a three step shift wedge that positions the spring loaded shift plunger and clutch.

    Yes understand forward and neutral are normal, reverse is the problem.

    2 vent plugs?

    Geez I hate to bug you guys again but I still could use some advice, back to the lower unit for the Yamaha c40elrq. Testing the unit for shifting before reinstalling yesterday I ran into a problem. Neutral is fine, free and no noise, forward the prop locks in one direction and ratchets the other...

    sn 6E9 L 552857 The center plug does align with the shifter wedge, probably more towards it's top but I couldn't tell by looking into it because it's so small. The plug itself is smaller than the top and bottom ones and is the magnetic plug.

    Shift Mechanism, interesting. When I can I will remove the plug and peek inside to see if/how it aligns with the shifter. Also I will try to interpret the sn number and post it, the tag is damaged and hard to read.

    2 vent plugs?

    I'm not close to the outboard now but I think the top plug, the one above the plate was labeled "Wash". If I recall correctly it taps into the cavity for the water pump so it must be for flushing. I have a service manual but it is one that has every Yamaha built, hard to follow sometimes...

    I missed some of that Jeff but the top plug is labeled Oil Level not the middle. racerone, there is a plug higher up closer to the pump for flushing. History: I changed the oil last year and didn't notice there were three plugs until the recent repair. I don't use the outboard much, I live...

    2 vent plugs?

    Sorry the top plug is not labeled vent/fill, I was too lazy to back out to the shop and check for sure, it is labeled "Fill Level" so no doubt what it is for but still would like to make sure about the one that is not labeled and should it be used as a vent?

    2 vent plugs?

    Finishing up replacing drive shaft bearings on a Yamaha c40, about to fill the gear box and found what I think is an additional vent plug that is not labeled on the top of the gear box housing, the upper plug is labeled vent/fill. Are both to be open when refilling then closing the non labeled...

    Prop Shaft Bearing Race

    Appreciate your reply, of coarse also weighing in on the decision is the $200 + to replace it.

    Prop Shaft Bearing Race

    Yamaha 1992 C40 2 cycle, but guess it really doesn't matter what the outboard is, top drive shaft seal failed, actually partially destroyed itself, in the lower unit and didn't notice it until the gear box started to whine. I have the lower unit disassembled and it appears the top drive shaft...

    4s full of oil

    OK answered my own question, the springs should return the choke to open once the electrotherm device releases but they are not. Seems the springs on the choke shaft levers aren't getting it done unless the choke solenoid core is in an exact position perpendicular to the swing. Appears the...
