    Milky Substance on 15HP Evinrude plugs

    Hey everybody, I just swapped a powerhead from a ‘78 15 evinrude onto a ‘85 15 evinrude. After doing this I have noticed a milky substance on both plugs almost like I am getting water into the cylinders.

    gray/black oil under outboard pan

    Hello everybody I have been continuing fixing up my old 1972 25 johnson. I noticed about 2 weeks ago a bunch of tacky gray and black oil gathering up where the midsection meets the pan and was starting to leak onto the midsection. After that I pressure washed it all off and after only a few...

I changed out the switch and inspected under the flywheel and nothing seems out...

    Serial # location on Chrysler made 7.5 Sea king

    So I’ve been working on a 7.5 Sea King and I need to know the serial number for it. The plate on the outboard mount with the serial # must have come off becuase it’s not there so I was wondering if there is any where else on the outboard with the serial number? I know for a fact the outboard is...

    '83 Chrysler 7.5 Sea King, cant get water pump housing off

    So I decided to do an impeller replacement on an 7.5 chrysler outboard I recently got running. So I took the lower unit off and got the water pump housing unbolted and found a problem. The housing goes around both the driveshaft and shift shaft and the problem with that is the shift shaft after...
