Hello, I have a 1978 70hp Evinrude, when I drained the oil from my lower unit it was a milky color. What could be my problem and if it is run again after replacing oil will it cause any damage to the motor?<br /><br />Thanks in Advance
Im no expert, but i changed my lower unit's oil today, and after sitting for 3+ years, it was also milky. Im sure changing the oil would do it no harm, and would prob. be better for it.
terry,<br /><br />A great percentage of lower unit leaking problems are caused by leaking fill/drain plug screw seals.<br /><br />Drain and refill the L/U and make sure you replace those seals.
Thanks for all the help. I am replacing the fill/drain plug screws and seals. I won't be taking it out though until probably next weekend. I will let you know if it worked.<br /><br />Thanks Again,<br />Terry
Hi, Terry.<br />Read this post. It may be of some help to you.<br /> LowerUnits 101<br /><br />While she is sitting there, place an old board or something under the l/u. You may find a drip of juice, indicating a bad prop seal or vent/fill screw gaskets are leaking.
Thank You for the link, that was a very helpful post. The motor is now running beautifully and am not seeing any indications of further problems.<br /><br />This is a wonderful group!<br /><br />Thanks Again,<br />Terry
