1. I am learning as I go so need a little help on Shift Rod height on a 1982 Evinrude 50 HP outboard. Model number is E50BELCNR. I removed the lower unit to determine why I was getting water intrusion into the lower unit oil. Had a local yocal replace seals in the lower unit and when I went to install it back on the motor I had shifting issues. (wouldn't go in reverse blah blah blah). Anyway I did some reading and found out about specs for shift rod height are very tight and was told the "L" in my model number indicated I have a long shaft motor. I am now trying to determine exactly what the shift rod height is supposed to be for the 1982 version of the 50 HP Evinrude long shaft motor. I did find some shift rod heights in the sticky threads but they only went to 1981. I can't find ANY specs for shift rod height in my SELOC manual. Any help would be appreciated on directing me to where I can verify proper height for my year and model motor. I was told the height was supposed to be 21 23/32". (please see number 2 below)

2. When trying to determine proper height I removed the lower unit back off the motor and tried to do a measurement to get the height I had been told on the shift rod. I noticed on doing so that I was a good 1/2" short from that measurement and there was not enough thread length on the shift rod to make up the difference without the shift rod completely unscrewing from the unit. I figured that I must have bumped it out of neutral when removing the lower unit so I tried to pull up the shift rod to get it back in neutral and the shift rod and detent shifter came completely out of the lower unit. So my two dilemmas now are 1) do I have to remove the bearing carrier and gears to get the detent shifter, ball and spring back in place? 2) I need to verify the shift rod height I was given is correct for my year model motor.

All insight is appreciated

Can't really answer your #2 question, but the measurement you got is correct. Measure in neutral with offset to front of motor. I use the shift bolt's pointy end to measure the center of the eye on the shift rod.

Thanks for the response Interalian. Using the pointy end of the shift bolt for measurement is a great idea. Can you direct me where you were able to confirm shift rod height? Many thanks

I to have the 1982 (CN) OMC Service Manual - spec is from there. Bought it so I could rebuild my CN '90 and convert it to a 140.

great, thanks so much. I have a SELOC manual and have been nothing but frustrated with it. I was looking earlier today at some used Evinrude service manuals on Ebay. Wow, a 90 HP to a 140 conversion! didn't even know that was possible. This is my first outboard I have tried to do any work on so I definitely have a earning curve. Have done some work on I/O but have limited knowledge on this stuff. But I love to learn and figure stuff out. If I can just keep from making it worse as I learn!

If you're planning to keep your current motor, the factory service manual is a must. Seloc manuals are notorious for incomplete and sometimes erroneous information.

90-140 is easy if you have a complete but very tired 140 donor motor to base the rebuild on. I took electrics, TnT, and lower unit from the 90 as it was low hours. Block/carbs/exhaust from the 140...
