Is it OK to fill the unit with oil with the upper cap off.
After installing the lower this week I wanted to check the upper gears. While I had the cap off, I thought Why not dump oil in here till the upper screw gets covered.
I added the oil slow and saw and heard bubbles coming from the lower?
Seems like the air came out. Any thoughts on this?

I want new seals for the drain screws. Are O-rings from the local hardware store OK? or should I get the made flat rubber ones?

p.s. I know the washers go UNDER the screw head. LOL

No. Pockets of air get left inside the OD. It's always "bottums up" for the OD oil fill and a cold beer when you are done. Don't use "O" rings because they will crush flat and not always seal properly. Buy a dozen of the correct oil seals from a dealer. They have just the right amount of give to provide a tight seal while keeping the scew from backing out.

X 2, No it's not safe to fill it from the top, even though you think you got all the air out.:eek:

Fill from the bottom to be safe;), It not worth the chance, Mercury went out of their way to test this theory for you all ready at your expense.:D
 
MY pump has Evinrude xp oil in it. Should I buy a "merc" only pump or would a little OMC oil be OK?
Guess I could do the bottle squeeze, I'll need that beer after that.;)
