Mark to view after I change my muffler bearings and hubcap gaskets.
You’re going to need a bucket of prop wash for that.
Muffler bearings last a lot longer if you periodically put some elbow grease on them. Trouble is, they use the metal shielded bearings because the sealed bearings won't take the heat. Crud gets in the shield and ruins the bearing. I got tired of changing them. So I ordered some miniature grease zerks from Switzerland, the kind they use in the high-dollar Swiss mechanical watches. Drilled & tapped the shields for the zerks. I use a mixture of elbow grease and a little high-temperature anti-seize. A quick squirt of grease every oil change and I'm good to go.
