Default 6 hp evinrude 1970s water pump impeller help

I am having a problem removing the lower unit. I removed the four bolts and it is loose but feels like it is stuck on some shaft or linkage or? so it wont come off. I also removed the bottom of the lower unit next to the prop but that didnt do anything either. please advise.

Welcome to the iboats.com forum. The experts here can help you solve any problem. While I am not an expert, I do have a factory service manual for my 1973 Evinrude 6HP motor. Will review that section and get back to you after I get some sleep. One of the other members will probably help you before I can make it back. Good luck with that great old motor!

Depends on the year. If it truly is in the 1970's, there is a pin in the drive shaft that must be aligned with a slot before it can come down. Do this:
1. Remove spark plugs
2. Slowly rotate flywheel while attempting to pull lower unit down. When the pin aligns, it will come down a bit. STOP TURNING.
3. Now look in the gap where it came down and you will see the shift rod connector. Remove one of the screws and the gearcase will come on off.
4. Once it is off, make note of the positon of the drive shaft pin so you can put it back in the same position. DO NOT rotate the flywheel while the lower unit is off for the same reason. That will minimize the jiggle and fuss required to get it realigned.

If it actually is in the early 1960's, the powerhead has to be removed to disconnect the shift rod.

You aren't the first one to unnecessarily take the gearcase apart. Heh, heh.
