Re: OMC outdrive damage: was I shafted? (RESOLVED)
Lakeliven, Yes I am/was OMC certified for Cobra probably two or three times at factory schools in the mid/late 80's and early 90's.OMC "Master Tech" in '89. I work'd, at that time, for the largest Johnson Outboard dealership west of the Missippi. We sold and serviced many, many Cobras and Mercruisers. Seeing outdrive problems on either is/was not unheard of. Some by normal "wear and tear", abuse/neglect on behalf of the customer, and some by "shade tree" mechanics (some who actually "work" at what you would say is a "boat dealer"). In 1989, I was the Pac. NW field service tech rep for all Evinrude and Cobra dealers in Alaska, Washington Idaho and western Montana. All warrantys from those dealers came across my deak for my review prior to being sent on to the factory for reimbursement. I often was in the field inspecting outboards and outdrives and determining why something failed, if it was warranty and authorizing repairs if it was... <br />I have seen a Cobra a time or two.. This was durring the "Cobra recall" period that many of us would like to forget about, so I admit to having too many dreams/nightmares about cables and gear sets...too many!!!!! Anyway, as I think about your situation, I believe the following... Having gears and bearing to inspect would be better but... Only three senerios come to mind at this early hour.. 1) The OD was destined to fail in it's life, no one can tell you when this could/would happen, but, mechanical pieces DO break and that why I make a living doing what I do... "stuff happens", the luck of the draw, who knows??I do not have an opinion on if 400 hours IS alot or not. It IS double the hours of a unit with 200 , and half of a unit with 800.....(800 IS alot though!) 2) it's possible that the input/u-joint shaft and it's seal at the upper housing could have been failing and letting oil migrate from the oil cavity into the u-joint bellows. This is not uncommon, HOWEVER, when the od is removed from the transom for servicing, the oil would be seen laying inside the bellows. Now, IF someone never removes the OD from the boar,this would not be noticed, so one could drain and refill the oil a few times and not notice the low/no oil situation. The amount of leakage/lack of oil would determine the extent of damage that could happen over a short OR long time....Again, the OD was removed at some time so .... if it wasn't noticed, it did not leak, correct?? and 3) the dealer/mechanic filled the outdrive incorrectly, ie: via the lower drain plug hole vs, the "correct" way, via the "middle hole". Reasons given in above posts... The result would be/IS... upper gear failure where it did not occur previously..Owner accepts a certin amount of liability when he works on your product. He admits to doing repairs incorrectly. Hense, he is at fault!! Let me repeat the following. Whenever I ask a customer (or in this case, the tech who changed the oil).. "You did fill the oil from the bottom, right??" I usually will get the honest answer, either yes or no! If it's yes, shame on him!! Good luck in your court case!!
