- [Donnie] In this video, I'm gonna show you
how to get to and change the spark plugs on this jet ski.
This is actually my second time taking these out.
The reason I changed them the first time
is that we got water inside the head there.
We rolled this jet ski upside down
and it got water all in there, got water in the oil.
So I'm gonna be showing you it's the same process
if you're just wanting to change them,
or if you actually get water in the engine,
this is the steps you'll take.
And I recorded this awhile back.
And it says, when I was researching this.
It says, if there is water gets inside there,
that be sure to do it immediately.
If you don't get that water out,
it's gonna cause a lot of corrosion problems.
So this was the next day and I'm doing this.
Or I've already done it and this is my second time
because it's still...
I think I got some water in the oil
and I'm gonna check it again.
But anyway, you want to first loosen,
there's 10 millimeter bolts
on top of those spark plug boots.
You want to take those out.
I've got one missing.
I'm gonna have to get another one back there.
And then you pull those boots out
that connects to the spark plug.
And once you take those out,
you can get you a spark plug socket and loosen all these up.
And just do that to all four.
And then what I'll do a lot of times
is you just get them loose and then I'll get a hose
that fits and then take them the rest of the way out.
But yeah, anyway, we was out jet skiing
and having some problems with this
and flipped it over and flipped it back.
And that's another thing I want to mention.
There's a decal on the back of these
I didn't know about that.
There's only one way you can flip them.
So be sure if you do flip this upside down in the water
that you look at that decal,
and it will tell you which way to flip it.
And that may of been what we'd done
is we flipped it the wrong way,
got water in the air box
and just filled that whole engine compartment.
The inside the engine and the oil full of water,
which made a mess.
I mean, the oil looks just like milk.
And what it'll do is the top of those cylinders
will actually fill up with water and it would get locked.
So it's kind of like hydro-locked.
And you got to start it and it'll just click one time
and your whole engine is just locked up.
And that could be what the problem is.
It's got water on top of the pistons, locking it.
So if you had that problem, that might be what you check.
You just pull your spark plugs out.
And like I said, I used to use a hose to catch the end of it
and pull them out.
Now, again, I'll mention,
if you think this may be the problem of what happened...
And if you look inside there
and that whole engine compartments full of water,
chances are this did happen.
I mean, it got inside the air box
and sucked up into the motor
and gets into the oil and everything else.
But once you got them all out,
you want to pull the trigger all the way.
It says to make sure that the throttle is fully open,
and then you start it.
And I'm gonna act like you're gonna start.
You just push the start button
and it allows your pistons to go up and down
and pushes this water out.
Now this time there wasn't much in there.
I thought I was gonna have more than this,
but it did have just a little bit of a mist,
and you will make sure all that's gone.
The first time I went through this process,
when I changed the spark plug,
it looked like a geyser coming out of those cylinders.
I mean, there was a lot of water in there.
But I have got most of it.
But whenever you're doing this,
you want to do it until all that water is out.
And then you can replace the spark plugs.
If that's what you're doing, I'm not this this time,
I did the last time.
I said, it's very important to put this NICs on it.
If you put a spark plug in there
and it is in there for a while,
and it happens to kind of corrode,
if that breaks inside of there,
that's a big major fix getting that out.
So anti-seize just kind of helps keep it from...
It's kinda the opposite of Loctite.
It kind of helps it keep it from seizing up
and corroding inside of there.
So yeah, you want to put that anti-seize
on every thread on the spark plugs.
It's a four cylinder and then put them in.
Now I use this hose just to put them back in,
'cause it's kind of fast and it's easy to line it up.
And surprisingly,
you can get them pretty tight with those
where you just got to barely tighten them by hand,
once you have them in with this.
So you'll go ahead and do that with all four.
Now I don't know for sure,
I can't remember.
I looked it up whenever I was doing this the first time
to get the gaps right.
You'll need to look that up
or I'd ask the parts guy what the proper gap is.
But I did gap these the first time,
but I don't want to say.
I think I know, but I don't want to say,
'cause I'm not 100% sure what it was.
But that's easy to find out,
just ask the person where you get your parts from,
or you can look it up online.
So I'm getting all those four in and I'll put them in.
Pretty quick job, pretty fast.
And one other thing I'd like to mention
is there is a torque spec to these,
for the spark plugs themselves.
I usually just use a socket and snug them up.
You don't want to get these too tight.
I mean, you want to get them hand-tight.
If you have no idea of the feel of what good and snug is,
you may decide to get a torque wrench
and torque these down.
I've never really, I know you should,
and probably professional mechanics do,
torque everything and their spark plugs.
But I always just get them good and tight, not overtight,
if that makes any sense.
But it was probably the best advice I could give you
or a better option that is to torque those down,
if you question how tight they should be.
My main profession is collision repair and painting,
but I am kind of the DIY when it comes to mechanical,
and especially jet skis.
This is a total new experience to me.
And I think I've mentioned this in other videos,
I didn't plan for these to be projects
that I had to spend time this summer working on.
And so since I didn't have time to spend
on my other projects,
I needed to go ahead and video this
so I'd have videos for you.
So if I spent a lot of time on this, didn't have time,
I've got a Jeep project I'm gonna start on
and some other projects.
But unfortunately this took up a lot of my summer.
This and my son's trucks breaking down
and things that really wasn't the plan,
but you know how life is.
You can't really plan
and always kind of makes it change on you.
Anyway, so worked on these a lot,
did some work to both my sons pick up and this and that,
and never did even get to some of the other projects,
which I hope to soon.
And I know that's the videos y'all like more.
Y'all joined and subscribe this channel
for mostly auto body and paint.
But I do a little bit of mechanical too,
as a DIY, just kind of showing you
how a backyard mechanic might do it.
So, now we've got those 10 millimeter bolts
I'm going back in with, I'm gonna tighten those down.
Now I'm using the impact just barely snug them
down a little bit.
And then I'll go back by hand with the ratchet,
to make sure that they're tight, but not too tight.
And that my friends is how you change the spark plugs
or clear the cylinders of the water
if you got the heads full of water.
Thanks for watching,
take care, and we'll see you in the next video.
