I searched all over to find a video on this but I either found incorrect ways of pulling the balancer or nothing at all, so I made a video for anyone who needs it. The crankshaft pulley is the harmonic balancer. It's job isn't only to turn a belt or two, but it dampens the vibration of the engine. If the rubber in the balancer is damaged, you will have a bit of vibration and you will hear it also. Mine had the rubber starting to protrude and as the engine ran, you could hear it and feel it. It also had a "wobble" when running which can destroy your belt as well as other things if not taken care of soon. Forgive me, I am not good on camera. The harmonic balancer removal tool can be found at any auto store. For this video I will put a link below to one from autozone which costs $26 at the time of making this.
Key points to remember when changing a harmonic balancer: Do not use a bearing puller. Bearing pullers will grab the edge where the belt goes and will just destroy it and ruin the balancer further. Don't be afraid to use a lot of penetrating oil whether it's WD40, PB blaster, etc. let it soak for 10-20 minutes. On re-assembly, concentrate on the center if using a hammer to re-install. I prefer a rubber mallet to get started. Tap on rotation, tap one side, then the other, then the other in either clockwise or counter-clockwise rotation to ensure the balancer goes on straight. Make sure the crankshaft key is lined up with the key slot on the balancer. More importantly, take your time.
The balancer tool will get tight when you are turning it. Most of the time, you will hear a "pop" which is normal. That's a good indication that the balancer has now started to move.
Safety is #1. Please use eye protection. Also, have a helper nearby to watch. My wife was on the side of the boat watching the jack to make sure I didn't move the engine or disturb the jack.

Thank you for watching and I hope this helps people out there that are looking for a video on this.
