[QUOTE="hezekiah, post: 438682, member: 19726"] 1996 Mariner 175 Magnum EFI - Serial OG360900 Got the boat and motor about a month ago. Changed the lower unit gear oil and replaced the drain screw, vent screw and both gaskets around screws. Afterwards, got to thinking that I had 2 old screws but only 1 old gasket. I guess I assumed it fell out and I didn't notice it. 3 weeks later (after running the boat about 5 times...never any runs longer than about 10 minutes at a time...maybe 2 hours total on the motor) I check the lower unit oil and notice it is extremely dark with a little discoloration. I immediately drain the oil and begin investigating. That's when I find the old gasket in the drain plug under the new gasket. So obviously this is where some water got in. I removed the old gasket and all pieces of it and cleaned off the new gasket good. Cleaned the hole, and made sure there were no pieces there - then re-filled the lower unit with oil. I have not ran it yet. Had planned to run it, then drain the oil again and re-fill it with new gear oil, and then depending on what kind of shape the drained oil was in - go from there. Is this the proper procedure? Hopefully I caught it before it caused any damage. Any advice is welcome, thanks. [/QUOTE]
