From TRASH to CASH

Well it appears that we have found the issue. Well it looks like it's not. Now we're looking pretty good. Sounding like a nice idle. I think our idle is just a little low but... And we're back. Today we're going to be looking at this little 25 horse mercury this time and see what we got going on with this thing. If we can't get it running, if we can't make it viable, and if we can't save it. I do have a boat and a plan for this thing to go on. So let's get it up to the shop and see what's going on. Here we've got our engine up here on a stand and now we're ready to look at this thing and figure out what's going on with it. And to me just looking at this thing I think I got a pretty good idea what's probably going on with it. Most likely the engine runs but judging that the lower unit has been taken off and then is not all the way put back on. What's very common with these engines is that they overheat and what's going on what's usually going on with this style is that a water tube comes from down here goes up and it's a copper water tube that then goes into this plate right here the adapter plate of the engine and it's got a rubber bushing around that copper tubing. Now a lot of salt gets up in there since this is you know partially exposed it's not all the way exposed but just salt build up from being a water tube and sucking raw salt water up there the salt will build up around that rubber grommet it'll push it in which then pushes the copper tubing in and then it loses water pressure and just dumps the water out thus losing water volume to the powerhead and they usually overheat at idle and at speed and just in general have an overheat problem so most likely the powerhead will need to come off this adapter plate will need to be looked at and then once we look at the adapter plate we'll have to put a new rubber grommet and possibly a new copper tubing in there to fix the overheat problem. Shift shaft is undone but really this thing's not that bad it's pretty clean for a 2010. I don't see a whole lot of problems everything seems to be plugged in um that's not done so somebody's obviously been in there maybe took a relay or something i need to definitely start by checking the trim because if i don't have trim on this engine it's not going to work for what we want to use it for so hopefully that trim unit works we'll probably need to clean the vst check all the the rest of this stuff to make sure there's no blockages in any of the water fuel take a look at the fuel injectors make sure they aren't clogged up and then see if we can't get this biscuit running actually i do want to check this trim unit first so let me pop this cut pop this cover off all these wires up into here and put some power to there and see if the trim unit is working beautiful well it looks like our trim's working so that's a good sign now let's hook this thing up to some water actually we'll probably put the lower unit back on or take the lower unit off and inspect it since it's already half off and if that's all good we'll stick that back on put some water to it and see if this thing will start knowing that one of our problems with this engine is possibly this water tube i got the lower unit off you can see here's our water tube what we're going to do is we're going to take this hose we're going to stick this onto the water tube like that and then we'll turn a garden hose on to see if we got any leaks coming down from the tube whether it's pitted and got a hole in it or if it's messed up at the top way up there you can see it's corroded pretty decently but not too bad so we'll put this on there turn the water on and see if we got any leaks well looks like it's not a water tube which is a good sign i mean look at that that's that's a great stream right there coming out the exhaust like it should well the good news is that it's not our water tube so that means the power head doesn't have to come off so that's a good thing we just need to check this lower unit here make sure the impeller looks good and everything's good with that and then we'll stick this back on the engine and we'll see if we can get it started this looks really good so we're going to go ahead and put this back in okay got our key switch hooked up got some fuel battery cables and water so let's see what happens nothing nothing at all okay so fuses someone took the fuse ha some jerk took the fuse okay now let's see what happens no fuel pressure feel the no fuel pressure so got no fuel pressure looking like we got to pull the vst because our fuel our high pressure fuel pump is not working so let's pull this vst off here open it up and see if the pump's just locked up and what we got to do there she is oh no no no no no no well it appears that we have found the issue the fuel pump is in like new condition barely used but it ain't got no gas in it knowing what our fuel looks like we need to make sure that we get the rest of this fuel flowing nice and clean got good clean fuel up to there now we need to blow the rest of this out pull this off pull the fuel cooler off we will need to pull this fuel rail off clean these injectors and see how much a fuel pump's going to cost us oh really wow well that's unfortunate okay we've got our 30 amazon fuel pump in here vst reinstalled checking everything we didn't have fuel pressure on the rail so come over here disconnected a bunch of stuff and we're checking we do have fuel pressure coming out of the vst but once it goes through here it goes through the fuel cooler and there's nothing coming out the fuel cooler so either this is clogged i did notice that this is bent like it got dropped so i don't know if that's the problem or this is just clogged but we need to take this out and figure out how to still cool the fuel and get this thing running though we are running it looks like we've got quite a few issues it's not getting enough air i'll tell you that because you take this piece off right here let more air into the manifold and it'll rev up nice and fine but it won't stay idling unless you give it air so if you take it off it's going to rev up so idling fine right now probably a little low on the oh so something's going on with either the throttle body or our idle air controller which is right here so we'll pull this thing out here and do a little bit of investigation on here we've got our old iac and here's our new one now let's go put this thing on see what happens we've got the iac back on we've got our throttle body and everything back on all this is put back together so now we're just going to fill up our water and then once our water's full we can start this engine and see if uh the iac was a problem and if we got a good running engine all right now we're looking pretty good sounding like a nice idle being it's a little low i may need to i might need to change out those plugs and cool the fuel i think our idle is just a little low but i think we're running pretty good we still need to figure out something with this fuel cooler here i got the fuel cooler disconnected just going through this right here because this is smashed but other than that i do have a broken coil here so a couple little things to fix now nothing cleans up an old used beat up engine more than a fresh paint job on the cowling so what we're going to do i got the pan here and i got the cowling here we're going to clean these up with some degreaser clean them all up once they're all cleaned up i'll get these stickers off here sand these down with some 220 and then we're going to spray paint them i don't know if i'm going to do yamaha gray or if i'm going to do white just yet i think the boat i mean there is a black piece in between here and the cowling so i think i'm going to do white just because the gel coat on the boat is white and everything else on the boat is white so that would make it look a lot better but i'm not 100 sure yet so we'll find okay we've got our cowlings all sanded down we're just going to wipe them down with a rag here just a clean rag wipe these things down once we get them all wiped down we will go ahead and use our tack cloth hit them with our tack cloth wipe them all off we're going to put them on a board and then we are going to spray paint these things i still am undecided about white or yamaha gray but um i think it's about to be a surprise we got our first coat on there looking a little sticky a little questionable in some spots it's not looking too bad our that's just our base coat uh yeah there are a bunch of nicks and scratches i don't care about those we're not in the business of fixing those for this engine now i do like the way this color is coming out though it's looking pretty nice so hopefully on our next coat it's going to give it that real nice gloss i'll lay it on a little bit thicker a bit smoother and it'll fill over that black it's because we're covering the black that makes it difficult to it does the color doesn't come out just the way you want it just yet but our second coat should really change that all right so check this out here we are and we are with our second coat now it's starting to look pretty shiny and pretty yamaha bluish gray boom that is looking pretty fresh i'm telling you this is going to look really good i do think that we are going to need one more coat you can still see some like transparency there in between the lines i still think this paint's a little messed up but yeah you can see how it's not laying just right like the the passes aren't mixing together the way that they should but other than that this is looking pretty good it is also very hard to cover up black with a you know bluish gray color or a white or any other color for that matter but it is what it is so we're going to go one more pass on it and we'll see what our final product looks like we got our third coat on the cowlings and they are looking pretty slick i mean pretty good if you ask me i mean for a can of spray paint come on that's looking really good i'm debating on whether or not to put the clear coat on there just because i have seen the clear coat mess stuff up and that looks really good as is a little shine to it actually these are really shiny i probably should have fixed those with some bondo or something but yeah be all right we could put some stickers or something on there for a can of spray paint these are looking really good i mean look at that look at that that is just awesome so all right now the next thing we need to do we got to put the top on here and then we need to put our gasket on the bottom as well as the gasket that goes there stick that back on the engine that's over there on the boat and then once we get the two gaskets on there get the side chap back on the engine we do need to clean the engine up a little bit because it is pretty dirty then we'll be able to see what the finished product looks like for an outboard that we probably have i don't know maybe 250 bucks in it i mean 250 bucks i have a good running 25 horsepower and a working boat not bad if you ask me all right now then we do need to go ahead and put the gasket on this this here's our gasket we need to flip the cowling over clean up the seam of it with some acetone get that nice and clean maybe even scratch it up a little bit i don't know how good this 3m uh is gonna stick but we're just gonna go ahead and clean it stick it on there the way it is without putting any adhesive on it and see how that holds up over time so that's what we're gonna do we're gonna flip this over clean it up and put it on now i have generally found that what you want to do for something like this is to get the gasket started like that then we will pull one little piece off of the thing then we can put the gasket all the way around on without this then we'll come back and we'll pull this out and then you can just kind of pinch this thing into position but that way it leaves it nice and clean all the way around so that's just the way i do it um when you're doing something like this that makes it nice and easy maybe you got a better way this doesn't really work if you're trying to put some kind of sealant or something or put it on after it's came off but when you put it on new and you got that like that that's just the way i found to do it that is a beautiful clean looking cowling with a nice fresh gasket on it so why don't we go ahead and take this thing outside put it on the engine and see what the whole thing looks like all together let's go look at that that doesn't look like a murkaha racing engine i don't know what does whoo from trash to cash baby this thing is clean yeah
