Hello, John Talley here with Boats.net. Today we're going to be doing a little
bit more work on our Mercury Verado 200. Today we're going to be using part of a
kit that will actually replace the seals and the o-ring on the shift shaft,
more specifically, the housing of the shift shaft. Now I already bought a kit
that comprises most of the seals and o-rings that are needed to reseal the
entire lower unit. Today we're just going to focus on the shift shaft, but let me
show you that parts kit I'm talking about. With this one part number from
Mercury, you actually have all the seals and gaskets and O-rings associated with
this lower unit that well, to do the whole thing. It addresses your input
shaft seal, as well as your output shaft seals and o-rings. Then it also deals
with a shift shaft and that's what we're going to deal with today. Now if you need
help doing those other sections, why don't you reference the playlist for
this particular unit and I can walk you through that. Well, we've got our three
pieces out of this kit that we're going to need for today, so let's hop over
there and get this taken care of.
Now we've already installed the input shaft seals as well as the housing. We've
already done a water pump on this one as well. Now we're gonna go ahead and do the
shift shaft. And guess what? After we finish it, then we're gonna dive down and
take care of that output shaft. Now this is really going to be easy. Basically
there are just four bolts that I have to remove. Now once we lift off the housing,
we're gonna find an o-ring down inside the casing as well as a seal
that we're going to push out of the housing and replace. Now if you've done a
pressure test on your unit and it is losing air or pressure rather? Chances
are, if you've located one area the other areas that have the same seals that are
almost as old or older, it's going to leak as well. So it is a smart move if
you go through the pain to drop this unit out, just to do all of it. I mean why
not? Because the hardest part is actually removing the unit and then reinstalling
it. As I was talking about earlier, all you have here is just an o-ring, which is
actually right here. When we go to install the new one, it'll go on this end
and then go into it. Then you have a gasket. There's a rubber washer on this
side, and here's that other seal I was talking about. So what we're gonna do is
take this over to the parts washer, get it cleaned up, get this pulled out, get
it greased back up, get the new seals and the gaskets and o-rings, and then just
put it back together. It's going to be that simple. We've got our gasket peeled
off. Next, let's reach in grab that seal. See if we can wiggle it out. But when
you're doing this, do not gouge the outer edge. Because if you gauge this as you're
coming up, guess what? That's where it's going to leak. With that removed, I'm
gonna take it over, get it cleaned up, then we're going to put the new pieces
back in. We've got her cleaned up reasonably well, so let's go ahead and
get our seal back in. I'm using just a 13 millimeter socket to sink it all the way
down. That should be it. Now we're going to take a little bit of grease and just
work it around the inside of that seal. That should do. Now I'm
gonna go and install our O-ring on this side, and put just a light coat of
grease on it where it's easier to get it back in the housing.
Alright, that's ready to go. I've got our rubber washer cleaned up. We'll wait
to put it on until we actually get the shaft to come through, put a little bit
more grease, and then we'll push this down on it. A new gasket. Let's push this
housing down. A bit more grease, rubber washer. Now let's get our bolts back in.
Make sure the gasket gets lined up properly so you don't damage it. Alright guys, that
wraps up this part of the project. What are we going to do next? We're actually
going to dive down and take care of that output shaft seal. Now if you would like
