Hello, John Talley here with Boats.net. Today we're gonna be pulling the
powerhead on our 2004 Yamaha F225. Now if you've seen any of the other videos in
this series, you know that this motor is in serious trouble.
We already did a leak down test as well as the standard compression test, and
neither one of them had good numbers. So let's head over to the table look at the
special tools we're gonna need, then we're gonna get this thing pulled apart.
So let's go. Alright guys, normally I'd have a whole
bunch of special tools laid out on this table, but guess what? We won't need any
for this project. As far as the parts? Well, we won't need any of those as well.
So all you're going to need are just some basic hand tools and I'm gonna call out
each one as I use it as we go through this process. So let me open up my
toolbox and let's go get this thing taken off.
Now as I said before you can tell I've already been doing a little bit of work
on this one. I've already got the upper cover removed, the covers over here, the
intake silencers. All that's been removed. What I'm going to do next is
disconnect anything that's going outside of the engine, whether it be fuel, or
battery, or electrical connections. Get all of those disconnected and at that
point we'll come around and get these lower covers, get those lower bolts
removed and lift that head off. Disconnect it from your battery first,
then we'll go up top and take care of the other connections. Now if you're
actually doing this with your out drive still mounted to the transom of your
boat, pretty much want to go through the same process I'm doing. The couple of
things that you'll have to do that I won't is disconnect the fuel lines. Next,
you need to go ahead and disconnect your main harness coming from the controls.
Basically now we're just disconnecting any controls that are heading out away
from the engine or sensors. As you're doing this, you may want to take a few
pictures as you're going along along, where you get them back in the same orientation when
we're done. Now I'm just disconnecting the trim control wires. It'll be pretty
easy to see where they go. When I pull off nuts and bolts like this,
I usually just pop them out and then hand screw them back in just a little
bit. We will probably end up taking all of the harness off of the engine, we're
just not going to do that right now. I want to lift it off as a complete unit
and then once we get it on the engine stand, then we'll start breaking it down.
What I'm doing over on this side, just unplugging regulator rectifier.
Once again if you were still connected to your boat, you would need to come
through and disconnect your throttle and shift cables. Of course I don't have any
connected right now, so it's not an issue for me. Now we've got all the cabling
disconnected, let's go ahead and pull these the outer covers. As you're going
through this process, as you pull it off each of these bolts, it all seems simple
right now. My advice is to go ahead and get you some ziplock bags, throw them in
there, label them. This is all simple right now, but in the several days that
it's gonna be-- or weeks even-- between when you were taking apart and putting it
back together, you're not gonna remember every single one and it's going to drive
you crazy. So go and do yourself a favor. Keep things organized as you're pulling
them apart if you've got the space to do it, which I do.
If you don't, bag everything up, put it in a plastic container, you're good to go.
Let's see if we can get them to separate now. Somebody kind of put it back
together up top and didn't do a fantastic job, which is binding up
everything else. There we go. Alright guys, well we knew somebody had already worked
on this one before and they had pulled the power head and decided not to go any
further. But when they put it back together, there's at least six bolts that
I've counted that they they missed, so we're gonna get the rest of these longer
ones. I think they only had four that they put back in before they sent it out
to me. Yes, we get those longer bolts out should be able to roll it over to the
hoist and get this thing lifted off. You ever look at an engine and feel sorry for it?
I do with this one, but guess what we're going to figure it out and fix it.
I've got it connected up, ready to come off, but I'm about to make one serious
mistake. I gotta pull the dipstick tube and the-- well, the dipstick and the
dipstick tube because of course it coes down in the oil reservoir. And there
we go. Now we can go ahead and lift off. We were about to make a mess out of it,
but we didn't. We saved it. There you go.
She has been decapitated. So let's get this out of the way. It is actually eaten
it looks like into the actual block itself, and it's spewing all out through
the exhaust. That's why it's dripping all over the place.
Well alright guys that wraps this one up. Only thing I have to do now is just
transfer the power head over to the engine stand after I attach an adapter
to it. Well listen, if you need any parts for your boat, once you come see us at
