First post, first time digging into a mercruiser or any marine engine.
I have a 1989 4.3 v6 175hp gm block, serial number missing. I was unable to find a block code that matched anything online. I pulled the intake manifold and noticed a strange wear pattern on my distributor gear.
I am going to replace it, but was looking for help as to what might have caused the wear? Also, is there a must-do ignition conversion for this engine, while I have the distributor apart?
Attached a photo of my gear.
And this is probably what it looked like new? https://www.ebay.com/itm/Mercruiser-Distributor-Gear-43-818807-8M0115498-/362830137479
