problem replacing lower unit oil....

Question

CALVINIST

I have an old Merc Kiekafer motor. I drained the oil, but when it came to putting new stuff in, it does not go in. I know it's supposed to come out the top hole, but when I try to put in the new oil, there seems to be a vacuum. I can get some in but obviously not all that's needed. I use one of those pumps you screw onto the quart bottle. I have also tried to manually force things too, but to no avail.

Any clue an what is happening and the cure?

Thanks in advance,

Casey

Did you open the vent on the lower unit?

There are 2 screws on motor.

Top is vent/max-level, bottom is fill/drain.

You have to open both holes taking scrws out and pump from bottom hole until it gets out from top. Then, close top plug, remove pump hose and close bottom. You'll loose a little but not much.

I did take both screws off, but it seems I can only get so much oil in there. Never does come out the top hole confused.gif

i had an older merc that had a 3rd screw almost like a regular phillips head, loosen this and the oil should go right in!

Did you open the one on bottom of lower unit ? It looks it's almost underneath.

Cal, How old and what model is this one? It's possible that the top plug you are removing is a "flush" for the water pump.

Bingo! Did just as you said, and it went right in. I was totally fooled, because I thought for sure the oil would come out the hole with the screw the size of a dime. Just below that was a tiny screw head I never would have guessed to be the vent plug. The other one must have been the one for flushing the water pump as boatfixer said. Thanks guys for your input. This forum rocks!

      Note to self.  Keep your "Packers Suck" T-shirt in the fishing boat for all future fish pics.   Ties are like head butts, everyone loses.

      And this is why you ALWAYS check out FM. I had a crazy busy summer as I worked full time so my weekends and evenings I was always doing somthing and I never just sat down. So I just noticed I missed this great “ goodie” package. Darn!

      A chain, a $20-$30 come-along and your set. Wrap chain around rafter hook up come- along and away you go. Been doing it this way for many many years without trouble.

      I'll say this. As a Vikings fan, Mrs. Skunked Again was pretty emotionally upset in the 2nd and 3rd quarters. She warmed up a bit when her team came roaring back in the 4th. I don't think either of us would have survived the four hour drive back to MN without a tie.

      Northern tool 1/2 ton chain hoist like 39.99 with gambrel works great.
    • Mike89
      I just use a rope and pulley set up. way cheaper too...

      I'm looking to buy a hoist for hanging to skin deer in the garage for around $200 can any one recommend one?

      Wow, nice mix of fish too. Only a real fisherman will rub a Slimer and go right back to eating his chips! 😅
