looking for an upper gear/pinion set 21/19.. Im wondering if the elec shift parts are the same? a guy on CL sells this stuff regularly and he has a elec shift upper gear set for sale..
Will the elec ring/pinion be the same/fit?
Howdy,
If the actual part numbers are identical, then yes.
Go to
http://epc.brp.com select your model and jot down the part numbers for the upper gearsets and compare to earlier stringer models. I am willing to bet that they're not even similar. (a quick comparison with the 1987 and 1986 models indicates they're not)
waiting for the oil to settle and bubbles to come up (my 1st time doing an omc). Filled it up to dipstick and thought it was good.
Please don't take this as trying to "beat you up on what you did" but your above description indicates that you maybe didn't just NOT wait for the bubbles to "come up". There's nothing in OMC Cobra service manual that suggests you should wait for bubbles to do anything.
If you fill it wrong, you absolutely trap a bubble(s) in the drive that will uncover the upper gears when the oil warms and thins out under load.
If you fill it (IAW the OMC manual) from the "FILL" port, to "FULL"
with the dipstick "resting" on top of the threads allowing for a slight overfill" (OMC's words) there will be no bubble you have to wait for..
It also really sounds like you may have filled it from the drain port......
OR, you didn't unscrew the dipstick so that you would fill it while it was resting on top of the threads.
Again, I am not trying to hammer what you did. (You feel bad enough as it is I am sure!) But I want everyone else who reads this thread to know that there is only one safe, OMC approved way to fill a Dog Clutch Cobra.
I know there are people out there that have gotten away with doing it differently. but there is no procedure that includes waiting for the bubbles to come to the top. (although I guess you could say that slightly overfilling it does essentially that......... you just don't have to wait for it)
I am really sorry this happened to you . (My previous King Cobra was replaced TWICE by 2 different "Dealers" who filled it wrong....luckily they replaced the drive both times without any "Lawyering-up"!!.......there was some threatening though)
OTOH, This might be a good time to consider getting an SEI drive conversion unless you can find a used replacement Cobra
You will need to completely disassemble BOTH the upper and lower to inspect and flush. The oil from the destroyed upper circulated metal debris into the lower. It's essentially a complete rebuild now. (upper and lower) A complete rebuild could cost nearly as much or more than just replacing with an SEI + adapter kit....
Also - any special tools needed for the swap?
I sold my OMC service manual with the drive when I pulled it all. I seem to remember several "special" tools required for a rebuild. But you could probably make some of them........ It's somewhat more complicated than rebuilding a rear-end but probably not "Rocket Science"
You can look at
http://boatinfo.no/lib/omc/manuals/1986-1998omcmanual.html#/488 to see some stuff on the Cobra(s)
It would be best to get the OEM OMC manual. I wouldn't use an after market manual like Seloc/Clymer though. Too many errors.
