lower unit lube

i recently aquired a 1968 johnson super seahorse 4 cylinder 60 hp outboard with electric shift. I consulted with a local dealer,and believe in his rush to help several people at once, he sold me the wrong lower unit oil. I have never owned an outboard but am learning a lot. i trusted the recommendation he gave me and after about 12 hours running the motor i happend to catch the warning on the container that esentially stated the lube i used was intended for non-electric shift motor 1973 and newer. now i am panicking that i might have hurt the lower unit or worse. can somebody please tell me what signs i need to look for to see if any damage has been done? what damage would be done in this circumstance? for the record i cleaned everything up prior to running the moter and tuned it and it appears to me run great. like i said i am new so moving on the water is great to me.

indy,<br />Don't panick.Just drain the oil again and install Premium gear oil.If you have problems...rechange it again to flush it out.I don't think you can do damage,just have shifting problems.<br />DHP
