Pulled lower unit lube plugs, no O ring?

[WhereBob]

I'm changing the lube on my 1990 alpha one sterndrive and I pulled the upper vent and lower drain plug and there are no O rings on these plugs? Is that normal? Should I get some and use them when I re-install my plugs?


Thanks

yes, get some for reinstall... be sure ya get the mercuriser or equivalent. they are not orings as ya think of them... they look like this

this one is blue, color got a little washed out by the flash i guess..

did any water drain out?

look close at the female side of the screw. them fiber orings get stuck down in the recess of the the drive....

They look like the picture that was posted and if you look close they are probably stuck in the case. Even if they are there I would replace them.

Yeah I did look for the O ring in the cavity and stuck my finger in there too...... nothing in there and didn't see any water in the old lube either. I take it I can only get those at the dealer? I'll have to wait till monday then. I went ahead and filled since we are suppose to freeze tonight and I didn't want moisture/vaporation to form inside there. I think if I keep the vent plug on I won't lose any lube when I take the plug off and should be able to hold with my finger while I put the ring on.

It's a flat washer plastick, home depot has them cheaper than the dealer.

I'll bet it is there, it has just hardened and looks like it is part of the case by now. If you take a pick of some sort you will be able to tell if the fiber washer is there. If it is, pick it out - in pieces if necessary - and put new ones in.
