Hello, John Talley here with boats.net, and as you can see we've already got our powerhead
removed all for our 40 horsepower Mercury Tracker outboard engine. Now I can go ahead and tell you:
this one's going to be in serious trouble because it's it's not sounding good in there,
but I want to see just how bad it is and if we can save this one or not. So if you're ready
I'll go open up my toolbox and we'll dive into this.
All right guys, since we cut cameras yesterday, I was poking around and found some unwanted material
in the base of the cowling. That is not a good indicator. So out came the flashlight,
started poking around, and you could see something that you don't want to see from the outside of an
engine, and that would be one of the connecting rods. So this crankcase is actually kaput. Now,
do I still want to rebuild it? Yes, but I don't know if there's anything that's going to be usable
inside of this thing yet. So before I go ordering a bunch of parts, let's tear it down, see just how
bad it is, and then I'll make a determination as to whether or not I want to fix it or not.
We'll go ahead and pull flywheel, intake, just the minimum that we have to do to get to
the uh, to where we split the crankcase. Okay, here we go.
All right guys, we've got the linkage arms pulled off,
now we're just going to pull the carburetor off.
All right guys, all I'm doing now is just getting the various lines
out of the way so we can go ahead and split the bottom half of the block open.
Now if you are worried about getting all these lines back in the right order, your best line of
defense? This right here. Just take pictures as you go along. Sometimes it's a lot easier
to reference your photos than to call it on your memory. But if you're still lost go to our
website, go to the exploded diagrams, and that's
going to give you an overall picture of how things should go back together.
All right, let's go ahead and get our intake pulled off, see what we see.
Uh...
Get this off...
output bearing...
I would bet this fuel pump is rather gummed up.
Is that it? Yeah.
Um...
Get the reeds out of the way.
All right, that one looks okay. Of course that one's completely trash, but here's the most
important part: I think the crankshaft may be usable. So guess what guys? We're going to keep
going. Since I am going to go forward on this one, let's go ahead and get the rest of the electronics
out of the way: the starter, etc., etc. That way we've just got a clean block where you can really
see what I'm doing and we'll completely break it down. Then I'm going to go start ordering parts.
I believe those three and that whole bracket comes off.
Oh look at that, bet you weren't charging too well.
Yeah I want to get off the flywheel now. 24 millimeter if you're curious.
This is when you go to your toolbox and get your puller of choice.
One I'm using this one made by Yamaha, or actually k-- K and L tools.
Whatever puller you do use, make sure it's got an adapter of some type that goes in
the center, because that's the end of your crankshaft and you don't want to damage it.
Let's see if we can get this to pop loose.
There we go, such a satisfying sound when it lets go.
So...
Oh...
So we'll take off this bracket, we can lay it upside down flat.
That is not the case today.
All right let's see if we can get her to lift out.
This one was on its way. It hadn't caught anything yet, but uh, it was thinking about it.
Let's see if we can negotiate this piston out of here.
About all you want, you're gonna lose.
That is not supposed to be there. That'll go on the wall of shame.
All right guys, that's going to wrap up this video. What I'm going to do next is go order up
some parts. I think-- once I get the crankshaft checked-- we're going to be able to get away
a couple of new pistons, connecting rods, and of course most importantly,
the block. Because well, there's no rescuing this one. Well listen if you need any parts
for your machine, why don't you come see us at boats.net and we can get you taken care of.
