1984 Johnson 150 Model # J150STLCRD
I can't seem to find accurate information anywhere or even an old used Shop Manuel for this engine. I'm not a close enough kind of guy and removing the lower on this old girl is a royal pain. Getting on the shift rod pin includes removing the bottom carbs and even at that it's very difficult to even see or get a tool on. So I want to do it once and do it right. I'd really appreciate if someone could help a brother out with this info. So far people have told me three different measurements, 22 1/16......21 1/16.....and 21 15/16 wtf????? Thanks, deep

Can't help you specifically, but can with my searching skills.
Found service manual I believe

May have found you a free version.
See if this covers it:

Found one on ebay for $20.00
Part # for manual is Johnson 394607

Thank you for your efforts SB. I've been through ebay and amazon and have found nothing specifically for this 1984 20" shaft V6. Model J150STLCRD to be exact. Called a local marina who've been around for many years and they gave me a fourth measurement of 22 1/8 +- . Hoping someone can verify for me.

Where have all the OSO tech wizards gone? I know it's old but is sure runs great.
