Howdy everyone.
Hoping you can lend a novice some advice. I'm trying to change out the impeller on a Yahama 8HP 6NO outboard. I've loosened the clamp thing on the shift rod, so that's free. I've removed the 4 12mm bolts and only been able to separate the lower unit about 1/4". It won't budge any further. I've run out of ideas so I hung the f**cker upside down. It's been hanging for 3 days soaked in degreaser and WD40 and hasn't budged. I'm afraid the drive shaft is fused to the crank shaft, but I have 1/4" gap, so that doesn't seem possible.

Anyone have some helpful tips for me? Did I miss a bolt? Do I just need to be patient? Is there another way to disassemble the motor to get at the drive shaft? Any help is appreciated!!

Wow, seeing that is a first for me. Pictured below is the LU parts blow out for your motor. Circled in red are the components required to come off first in order to drop LU. Sounds like you've done this though. Other than the shift connector and bolt, and the 4 LU bolts, there is nothing else used to button up LU. Have you tried using a friend, he/she turn the fly wheel by hand clockwise while you jiggle LU counterclockwise, see if it budges.
