Hello,<br /> I have a '96 Evinrude 88hp. I just changed the lower unit oil yestarday. It was a brown cream color ( dont know what oil was used). After I changed the oil, I hit something underwater, and damged one blade on the prop ( I think it was a submerged plastic patio chair). I didnt know this until after I got home. So basically I ran the motor at about 4500 rpm for about 5 minutes. Then 1000 rpm for about 20 minutes. It was not vibrating alot, and the shaft does not appear to be bent. I pulled the prop, and drained the oil. Now the oil is a creamy dark mustard color. Im using OMC high vis. oil (whatever the book says to use). So now Im wondering:<br /><br />Am I getting water into the lower unit? (dark mustard cream color)<br /><br />I kept both oils (new / old) in a clear tupperware container. Its been over 24 hours, and they look the same. I dont see any separtion of water from oil. So I dont really know if I even have water in the lower unit. Wouldnt the water and oil separate eventually????
