Just picked up a 1988 mariner 75hp thats been garage kept since it was new. literally looks brand new inside and out and starts on the first rotation of the crank. it has oil injection on it and it works as of now since the compression is 137, 136. and 132. Should i trust this long term? maybe...
just picked up a 70hp mercury 3 cyl 0b194791 and the guy before me thought it would be great to unplug everything so I need a wiring diagram mostly for the circuit board but ideally for everything. thank you!
Just picked up a 1986 mercury 70hp 3 cyl for 200 bucks. checked the compression and I had 100 on top 90 in middle and 100 on bottom. I didnt check for spark as the previous guy unplugged everything for some reason when he took it off. I have a video of it running supposedly from right before...
