Ohhh, amphenol pin, well I can check this off the list of sources for my engine failure.
About a month ago I found it on the cabin sole of my sailboat, ever since it's had me wondering. Esp when my kicker quit recently, I was convinced the mystery pin had something to do with it.
Kicker is 1989 4 hp Mariner #6e0-336357. The pin probably fell out of some random unrelated electronic component I was working on or cannibalizing. No worries, I found part of a crankcase lower oil seal when I pulled the lower unit a few days ago, just resting there on top of the water pump housing. So the seals going out makes sense as to why it's never quite ran right since I've owned it.
I've actually never replaced lower crankcase oil seals before so any advice would be above and beyond for either of you given this threads limited scope.
