Re: Lower Unit Fluid Change
Washers now are pale blue and should be easily visable if stuck in the lower unit housing.<br /><br />Agree, you can't run the lower unit without one as the threads aren't designed to seal on their own.<br />---------------<br />When you stick your outboard into water, the water is almost always cooler than the outside environment. So, as your lower unit cools down to this new environment, it creates an internal vacuum. The vacuum sucks water in via the screw threads if you don't seal it out.<br /><br />New, vs old, in a pinch, if the old one is not deformed, or torn I use them. But preference is to have some handy and always use a new one.<br />------------------------<br /><br />Agree with the bluish tent to near black Merc oil...Be tickled it was that color and not milky yellow. Grin<br /><br />FYI<br /><br />Got some Synthetic Pennzoil lower unit fluid the other day and it is gold in color (noticed it met GL-5 requirements and was not hypoid type (whatever that means) which is what they all used to be; very clear. Exceeds all mfgr's warranty requirements for mechanical shift engines. Got it at Wally world since my nearest merc dealer is 50 miles away, and it's made by Pennzoil, and if you can't trust them you can't trust yourself.....er ah..... Grin.<br /><br />Noticed Detroit has started putting syn oil in differentials of lotta new vehicles today. Great since it never gets any attention, and hard to drain, should provide superior service....course, when's the last time you lost a rearend in your vehicle?<br /><br />Mark
