How to Make a Homemade Boat Motor for Under $90.

so three to seven with truck bed trailer number three and a hole in a push mower it's a Honda yard-man just picked it up yesterday I picked up a day before yesterday I fed up a locked up Evinrude I'm gonna take the two and make one that's right homemade but murder number three and don't forget to sub so I've made it home at the push mower it runs great but the self-propelled systems messed up yeah it's something I probably fix but I don't need it I've got this one that I won two years ago I'll leave you a car for that right here anyway don't need another push mower so I'm gonna take this engine put it on the boat motor the boat motor is froze up you could get it unstuck you get it run again I don't really like working on two-stroke engines I prefer a four-stroke engine so much simpler to me and this one air-cooled don't the worry about the water pump regular gas not to mix guess I just like the simplicity of a air cold regular gas but motor so that's what we're gonna do with this guy please that's the plan step 1 I've got to pull this power head off and I should probably know a little bit with this first before take it apart let's do that now so to the front cover off the new mower guy thought it was maybe a gear issue I think it might be a pulley issue the 2-piece pulley one should be a one-piece pulley now what if we should pull the swap it so with no faster second thought that wouldn't help the boat motor project at all I just googled the model number on the boat motor it's a 6402 - see that says it's a Evinrude six horsepower I'm estimating that mowers probably six horsepower now the only catch is the mower may not turn as fast as the two-stroke but motor did but it should have plenty of power it was about 15 minutes worth of checking out seven screws 5/16 heads not much to it I guess up next I need to clean up this foot a little bit and then start taking the engine off the lawnmower getting those ready to go together so I had some cylinder curiosity hitting me 10 bolts the hip hop off there's a little bit of water damage in there that's what looks like on the inside very little abuse I see one broken spot here the net looks really great oh and if you look to the side my neighbor just gave me a table saw we'll look into that after this suppose Alize got a burnt-up motor another piece of cake here's the self-propelled belt there's the blade plate look pretty good and the engine three bolts later it's loose I just unhooked the kill switch that goes up to the handle on the handlebar and now I'm gonna shorten the pull rope and the mower deck it was rusting and cracking right along here feels about done anyway spilling my gas it's now gonna get this off somehow could have pulley off and that that we're in now on the foot the drive shaft is about a 3/8 inch stainless steel shaft it's got four splines on it that's gonna be something hard to make some hard to adapt to but if we use what was made for it hang on a second this is the crankshaft that was made to go on that drive shaft if I can somehow use that I've got the engine taken apart I think it may be cut off here that's pretty close to what the lawnmower chef does anyway lawn mower is a one-inch keyed shaft that's pretty close to a 1 inch high I'm right where I wanted to be I've got the block all taken apart I got the crankshaft this is the piece I needed to go on the drive shaft on the boat foot then this part will cut off here cut off there that gets adapted to the bottom of the lawn mower engine and as an added bonus I get this cute little keyring sighs piston rod there's actually another one or two rip that out make a contest to send it to somebody we'll see let me know if you'll make some kind of contest giving away a miniature piston and rod I've got the crankshaft on the drive shaft if we spin the crankshaft propeller spins neutral reverse we just got to figure out now how to adapt that to that and get the engine mounted then head to the river the crawdad catcher is back with a baby crow dad and we're to the technical part of the boat motor the Sun started go down I got to pick up the pace just a little bit the plan is to cut this is the crankshaft out of the button our engine cut it right here and weld on this this is a one-inch keyed adapter weld it on right there and we've got it made $15.99 it's got two Allen bolts or the blade holder we could cut it off here but there's no allen bolts I don't really know if it needs allen bolts I kind of want them option three the self-propelled pulley very little key not a whole lot of collar I'm gonna throw that one out I'm leaning towards this but if you want to do it for free that would do it and then in the back I've got some bolts the engine ball gone with three bolts I got longer bolts I'll cut out some pipe and I got this cut off will to go right through there I'm gonna cut it off first and then we'll grind it smooth got to do a little bit of welding that's next I've got a crankshaft in the vise I've got the grinder ready the goal is to cut off right here let me use the cutoff wheel I'm tied to cry no we'll make it smooth then we'll start welding [Music] well that was quick and easy and now with help from the grinder everything sitting pretty much smooth the adapters gonna go just about like that or heck we could do it like this give it more welding surface well here well oil on there now if you look at this is the counterbalance I might cut a little V groove right here take some of the weight off this side and then I give you a little bit more wedding area that's what we're looking at but a straight edge on it flat it's ready to go the V notch has been cut in the counterbalance I've got everything I will polish up smooth even the bottom of the adapter I'm gonna line it up put it in a vise and start welding and here it is all welded together I got the hole welded up the V has been welded to pick together I'll clean it up now put a little paint on it then we'll go put the motor together well that's probably a tomorrow thing it's getting late then we'll put them over together I welded this scale last night and I just got to thinking about it what if I got the welder and I put a little little weld here a little bit of weld there that will make it more balanced let's go do that [Music] this is how the adapter turned out looking the lights I was this side that's where that hole was that tried to fill in some here fill in some there looks to me like it's perfectly balanced good enough then I take that flapper will and the grinder to sand it down a little bit smooth it up I'm ready to paint and good put together let me use this u-shaped plate bolt this down to the foot and they get two pieces ain't learn and use the original three bolts I guess make it four bolts that bolt to the angler that looks stronger to me that looks safer and this is off of my second homemade but my reels at twelve and half horse when I put the bigger propeller on how to drill a hole to the prop shaft and while testing it broke that did find the propeller it was right there on the boat ramp what look so my next step I need to turn this boat motor upside down and Mark where I need to drill my holes into this plate so this is getting so close I can almost taste it it's starting to get dark too I need to hurry up anyway I've got one two three four five holes drilled that one I missed a little bit there's a bolt in the bottom I couldn't trace it so I ball it and we'll make that hole bigger I can make it work I gotta cut a little notch here and then on this piece that goes down below I had to take it off and it was a bumper here to cut off how to cut off this little bump here get off it bump there now this should go back home four bolts so I'm gonna go back to the garage cut that part out and make that hole bigger we should be cold okay it's after dark and the good news is this piece of Swiss cheese here I just drilled six new holes I got six bolts in there there were six bolts hold man you know originally what else I had to cut around for that bolt cut around for the shifter hopefully this be the last time I need to use this plate on the homemade engine it is now I guess tomorrow get two pieces of angular and drill the holes for the engine mount the engine go test it this is the next morning update I just went in the garage and cut off of this much of the crankshaft now the crankshaft don't even reach the adapter the adapter he goes in about ancient three-eighths I'm about a quarter that that means the hole is going to lower down and we'll be cutting off these brackets about a inch and 3/4 for this one about an inch three core that one I've already got the back angle for the back bolt I'm using the stock bolts and I gotta cut it I'm gonna go cut right now a piece of angle arm for the front I also had to cut the key that goes in the crankshaft so once I get these two cut get the front angle iron cut drill my holes drum a whole drum all three holes will be ready to put together it'll be ready to run the good news is I got paint the bad news is it's not even red blue it's more of an easter egg blue my local hardware store didn't have a whole lot of variety and I didn't want to wait gotta get this thing together I gotta paint the other side steel it is the very next morning I just bought it on this bracket the good news is recycle recycle recycle every bolts everything else is lock washers lock nuts gradate if it's gold it's great eight up next I got these two brackets on I'm gonna bolt them to the bottom of the engine and then my dapper goes in and then we bolt the engine to the big blue bracket I just took a piece of wire and I turn the key on and then downstairs I was checking out the propeller it needs a new split pin caught a key we're gonna put that in right now the propeller is in really good shape I believe it is first one test town there was one little spot where the adapter was rubbing on the motor mount put up a little grease on it it'll make some clearance I need to shorten the pull rope and then hook up a throttle to the carburetor right now we're just gonna learn whatever speed it runs and I'll probably do something better with that kill switch too and now just for the fun of it I got a kicker in a trash can trash cans full of water let's see how it does in the water they'll say much fun let's try it again
