I just acquired a 75 hp Evinrude. In doing the initial assessment and preparing to do a compression test, We found a lot of grey oil in the cylinders. Turning it over without the plugs blew tons of oily junk out all over the place. We cranked it over until most of it stopped and then tried doing a compression test. The tests were anywhere from 150 psi to over 180.
I don’tthought about getting it running to burn off some of the oil inside and do another round of compression tests.
The motor would not fire and in inspecting the plugs again we found there was a lot more wet greyish oil on all plugs and dribbling out of the plug holes.
Because we had the muffs on, we are wondering if this is water mixing with the fuel and oil.
Any thoughts on what I should check next? Pull the head?
