Willard, I have a 1978 90 merc inline 6. We fished out of the boat monday and as I was going back to the ramp I heard a noise like something rubbing. I pulled off the cowl today and was scared to death when I saw little aluminum shavings shining in the sun. After looking closer I found that the distribitor pulley was rubbing the distibitor bracket under the pulley like the shaft had fallen. I have a spare engine with the same distribitor and its pulley is a good 1/4 inch off the distribitor mount like the other was about 50 hours ago. Is there a bushing that coukld wear and cause this? I did grease the fitting before I ran it. I would like to if possible rrepair this distribitor cause there is nothing like having a spare part. Thanks in advance.
