How to run engine out of boat

in this video i'll show you how i hook everything up on my mercruiser 3-liter engine to run it out of the boat so let's go ahead and get started all right so first thing here i'm going to go ahead and take out this whole exhaust pipe so that way we can put it on the engine because this is really going to help us direct the exhaust and the water that's circulating through the engine and direct it out of the garage because otherwise if i just had this exhaust riser piece on water is going to shoot straight down next to the engine and uh we'll have a wet mess on our hands so i'm going to go ahead and take this out now then we'll go put it over by the engine there we go all right i'm just going to set this down here for now and then of course oh don't forget the exhaust riser itself this bad boy is going to need a new gasket this one basically tears up whatever gasket you put on it instantly almost all right next thing you're going to want to get is your battery oh boy this is i forgot i got the biggest battery they have oh boy and you're also going to want to get the main battery positive and negative cable out of the boat too for this all right got my battery cables here okay the next thing is for the water circulation hose so you've got the hose coming off the back of the engine like this and you've got your garden hose and you can't exactly hook them straight up so what you might need is a nipple adapter for your hose now mine's a three-quarter inch inner diameter so that would be the size i would need yours should be the same but it might be different so double check that but in my case i didn't have a nipple adapter for that size but i did have it for half inch inner diameter this is actually what i used on my sea doo for running it on a water hose it just so happens this hose fits in to this hose just perfectly so that's what gets the job done for me but if you go and buy the right nipple adapter for your garden hose that should be all you need so now the next piece is hooking up some sort of a fuel tank now you obviously aren't taking your tank out of the boat but you might have a five gallon red gasoline can hanging around somewhere but i actually like to use a clear water bottle that's because as the engine runs and sucks the fuel out i can see that it's sucking the fuel out of the water bottle so that's just what i like to use and the fuel hose going to my fuel filter fits just perfectly into the opening of a water bottle so that also makes it nice where i can just stick it on the end like that so before i move on with hooking up some of the electrical stuff the big concern i have first is with the exhaust riser piece when i had to take it off for removing the engine out of the boat the gasket on this rips and tears a little bit which isn't good so basically i need a new gasket and i've got one ordered but it's not here yet but i can try to still hook this up today and use some of the gasket maker to put on here and really the big concern is just that the water coming through these outside ports can leak inside to the exhaust chamber that goes down into your exhaust manifold and it can leak through the head valves into your cylinders and that's my big concern and that's what i don't want to happen but i can try to hook this up and then uh run some water through it and i actually have a probe camera i can stick up through the exhaust riser and i can see if any water leaks through the ports into the main exhaust manifold so that's what i'm going to try to do first i'm going to put a little dab on here separating the exhaust main port between the water ports i'm not as much concerned right now about the water leaking outside of it on the outside of the engine because i'm gonna have to take this back off when i'm putting it back in the boat [Music] all right but i should have my wrench ready to go not going to get this super tight yet just sort of down to where it gets snug because the riser is pretty heavy by itself then i'll let this set up for about an hour or so and come back and sort of crank it down so while we wait for that gasket maker to harden up we can go ahead and start hooking up some of the electrical components on the engine now to start with the main battery cables from the battery to the engine you'd hook them up just as you would with it in the boat so you have the positive one going to where it is on the solenoid for the starter okay then you'd have the negative one which is going to go to one of the stud bolts that just grounds it to the whole engine and no sparks there so that's good it's always good just to while you're not touching the metal just to double check to make sure there's no sparks in case something were actually shorted out also if you're wanting to follow along and you'd rather have the steps laid out in a document i actually created one on google docs that i'll leave a link to down below so if you want to follow along that way you can use that as well so now the part that most people probably want to know about is what do you do about the wire harness connector now i found on one of the forums online what you need to connect here but i have a 10 pin wiring harness so if you have a 14 pin or a different pin one it might be slightly different but you should be able to find some notes on that online to what you need to hook up so for my engine with the 10 pin harness there's actually only three pins in the harness that we care about for running the engine right now there's pins five and six which you can jump together with a wire keeps the engine powered and running as it's going but then pin seven when you supply power to that from the battery that's what engages the starter to initially start it so what i'm going to use here is actually two on off switches one for engaging the starter and then one for killing the engine after it's running now i am running low on switches here so i'm actually reusing that rocker switch that i put on the back of my boat then i have another switch which is actually from some of my high school robotic stuff so this first one that's not quite as beefy i'm using on pins five and six and now this one i'm going to connect from the battery and put it onto pin 7. so after hooking up both switches your wiring harness should look like this okay and that is it for the wiring it should be good to go i should be able to test to see if the starter will engage and hopefully it will yep that's a banger right there and no sparks blue so that's a good sign so now i'm going to go ahead and finish waiting for that to dry up then we'll go ahead and run some water through it and see if our exhaust riser gasket is leaking or not all right so i've waited over an hour to let the silicone gasket maker harden up a little bit so now i'm gonna go ahead and finish tightening these bolts down and you really can't ever get these ones too tight so now that that's ready to go i'm gonna go ahead and get my snake camera probed up there and into position then we'll turn the water on and see what happens so here is the snake camera and it actually connects to your phone so then you can stream the video live to your phone and record it there as well that has a light on it so that's cool okay so after three minutes of finagling it in there you can finally see where that edge of the gasket is all right so now i've got this crazy bucket contraption to catch the water and i've still got the camera up inside there so now i'm going to go ahead and turn the water hose on and we'll see what happens you can hear the engine gargling as it fills up i think it's almost to the top now the water has started coming out of the exhaust riser i don't see any on the camera yet boy let me tell you it's a little hard to navigate that probe camera up in there but we were able to see the edge of where the gasket was as well as down below to see if any water was dripping down from the other side that we couldn't see and i let it run for about you know three or four minutes and we filled up a five gallon bucket of water and i didn't see a single drop inside the main exhaust ports that's a really good sign i think that's probably good to go to test so now we're going to get this bucket out of the way and we'll hook up the rest of the exhaust pipe and then we can give her a go hannah hooked this bad boy up all right that's good to go all right i think everything is good to go at this point i got my water bottle filled up with some beautiful orange gasoline probably not the best for the engine leave your thoughts down below let's go ahead and give this bad boy a try this is it power on starter we just sucked here about half of the water bottle i don't want to need a okay i think i'm going to swap the water bottle out with an actual gas can all right that's a lot of tricks i think that's war enough in the gas can to get it all right let's do this again but there you have it that is how i hooked up my engine to be able to run it outside of the boat and if you have any other questions be sure to leave a comment down below and if you appreciated this video and
