1990 Evinrude 50 (TE50TLESF) Lower unit

[Ginder75]

My new motor came to me after the previous owner disassembled the lower unit to install a new water pump.

While he had the motor apart, he passed away. So several months later when his wife is clearing the shop. She sells, the boat, the motor, and all the parts she can find. When I get the motor, the wires are unhooked and the lower unit is missing parts.

Thanks to all the good folks on this board. I have the wires back in place, or on thier way. And I have a majority of the lower unit parts on order (I was missing the entire shift linkage and the water pump assembly).

My question, is on all the exploded views. They show a shift lever that connects the shift rod to the lower unit. I have not been able to order this past, but last night I came across a website that indicated this part was not needed on my motor.

Anyone have any insight to this? Under the ishopmarine.com website, it is part 27 on the parts breakdown, but it is not for sale.

Thanks,

Ginder75

No one willing to make a guess at this? I was totally confussed when they picture a part in the exploded view, but then say it is not needed on my application. I thought the lower unit they pictured was MY APPLICATION.

Thanks for all the great help.

It would help if you could post the explode view and indicate exactly what part you are talking about.

I looked at parts book on line. I think the part you're talking about is the shift lever. It looks like a dog leg right? and it is part #46 in the diagram, and it goes into the shift cradle. I get the same message that it's not needed on this application, but i don't know why. Anyway, if you look at other models of 50 hp for 1990 it shows this shift lever and gives the part number as 0332492 and it costs about $4. If someone disassembled your gearcase this shift lever should still be attached to the part directly above it, the shift rod connector which is #42 in the diagram and part #0332508. There's a pin and cotter pin that hold these 2 parts together and there's really no reason to ever take them apart. I know this doesn't really answer your question but maybe someone else can help out. I guess the mystery remains: why does it say "not needed for this application."

That is it - The dog leg looking part!

I am still confused! I guess I will wait for my parts to arrive and see how things go together.

The previous owner removed all these parts while installing a new water pump (not sure why!). But while it was apart, he passed away and now the motor has a new owner and is missing parts.

Where did you find the part for $4? I guess I could order it in case I need it when I go to reassemble the lower unit.

Any tips on how this all goes back together. I see the pins and threaded fittings. But how does the "Shift Lever" actually attach to the lower unit? That one part has me confussed!

Then I guess once I get all the parts back into the lower unit, I can set the lower unit in Nuetral and turn the upper shift linkage to nuetral and then thread the shift rod in/out until all the parts align?

I will look at posting a parts diagram if it is still needed.

Thanks,

Part number 46 in the exploded view.

Thanks,

The shift lever is attached to the part above it (the shift rod connector)with the pin and cottre pin.. Also, the shift lever has 2 little arms that fit into the part below it, the cradle. The lever and the cradle just fit together-they sort of slip into each other, there is actually nothing that holds them together. This will be more obvious when you see them.

Re: 1990 Evinrude 50 (TE50TLESF) Lower unit

For assembling the gearcase: You have to first thread the shift rod into the shift rod connector (which has the shift lever attached to it) and then lower the whole thing into the gearcase until the arms of the shift lever slip into the cradle. This is different from many gearcases where you put the thing together and then insert and thread in the shift rod. Also another unusual thing about this gearcase is that moving the shift rod up engages reverse and moving it down engages forward-just the opposite of other gearcases.

Lorin,

But if the shift lever is not need, then how does this whole assembly work? That is a MAJOR Question I have!

I have a real good picture in my head of how all this works know, Thanks for everything.

How far do you thread the shift rod into shift rod connector? There appears to be 1 inch or more of threads, so that could be considerable adjustment. I am sure I can figure this out with trial and error. But any tips to save two hours of shop time will greatly be appreciated.

Where can I get a Shift Lever? Still a missing part.

The lever is needed. The message that it's not needed is a mistake.
I've rebuilt this gearcase a number of times. To order the lever go to ishopboats or bombardier and look up Evinrude 1990 50 hp. But dont select your model number. Select a different model number until you find one in which the lever is available on the gearcase page. I know its available under some model numbers because that's how I found the part number of the shift lever. You should then be able to order it.
The shift rod screws all the way into the connector. This is not a gearcase where they give you an adjustment height. I think a friend has the service manual for this motor. I'll try scanning in the gearcase rebuild pages and posting or emailing them to you

Thanks Lorin,

I got the part on the way, I can't wait to get this thing up and running! Should be an improvement over my 1967 Mercury 35 hp!

Memory failure on my part-there is a shift rod height adjustment. The height is 21 15/16 in. plus or minus 1/32 for the long shaft.

Re: 1990 Evinrude 50 (TE50TLESF) Lower unit

Okay,

Now that you have given me SPECIFICS. when I have the shift rod removed and I am installing the coupler. Will the 21 15/16 be from end of the shift rod to the end of coupler. OR will it be 21 15/16 from the mounting hole in the shift rod to the pin hole in the coupler.

I know I could feel my way through this, but since you are offering details I thought I would ask.

Thanks for everything, I have assembled this motor 200 times in my head. If the dang parts would make it here I would be on the water!

You measure it only when the gearcase is completely assembled and the shift rod is completely in place. You measure with the gearcase upright, in neutral, from the top surface of the gearcase to the center of the hole at the top end of the shift rod. The offset at the top of the shift rod is pointing front. You can use a tape measure.

Lorin,

You have been GREAT helping me work through this!

Thank you
