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!!
