Yes he has a lot of talent! However, he is making a couple fatal errors. This motor will never run without the Reed Valves he deleted. He really needs to get a copy of Two Stroke Tuner's Handbook. Read and most important understand the theory of 2 strokes. They operate very differently than car engines. Some say they are simple. Actually the flow dynamics are more complex. He should also contact the guy that posted his evinrude V8 in a volvo here 7 years ago and understand the problems/solutions that were encountered on his build. Doing these two things will save him lots of money and heartache!!! I hope this note gets to him!!!

@@nkuntroll247 I tried to get in touch with them but they where very secretive about the whole thing. He did not delete the reed valves but he made a new intake, I am thinking about making two Y-shaped intakes in line with the cylinders on my similar 2litre V-4 project. Or perhaps make a "oil pan" plenum like Stvdrag225 here on KZbin did for his V6 SeaDoo GSX, really mean machine! :-)

[@nkuntroll247]

@@thehaze1972 He appeared that he removed the reeds with the original intakes as they are a part of it. My opinion it would be easiest to run the engine carb side up. Make 90 degree intakes for the carbs. This goes for any 2 stroke outboard conversion. It will run just fine this way. There is no oil in the motor, the cylinders don't care which way they are pointed. Also with them pointing down there's less chance of air bubbles in the cylinder head water jacket. The most important place to cool. It does put the crankshaft high though. Remember the factory spent lots of time and money optimizing the design and their are many reasons for it to be the way it is. I'm just saying understand all these reasons before making changes. No offense. He is a smart dude. But it's obvious he doesn't understand two stroke technology! The ultimate would be to get Honda CR500 pistons and cylinders, and marine crank, work out the port timing with the crank stroke, and custom make the crankcase. If a V8 it would be about 500 hp with minimal weight.

Constructive criticism. 1. I applaud your drive and enthusiasm for tackling this build. I can't wait to see the results. 2. Clean your metal before you weld. Even if your not good at welding it will be a better weld than dirty metal. Keep it up. I hope you are successful. I want to see this driving too.

He deleted the reeds!!! It will never start let alone run properly. However, I do agree with you. The other auto conversion of this engine type I am aware of has expansion chambers for each cylinder. That's the best way to handle the exhaust. On kawasaki triples I have seen 1 smaller chamber made for 3 into 1. If you are good with math and 2 stroke theory you may be able to make it work. But I don't know how well as I think the reflected pulses (which make chambers work) would collide with the next cylinder exhaust pulse. The reeds need to go back on and run the engine carb side up.

You only need reeds and tuned exhaust to create vacuum. Forced air does away with all that.

[@redavis460]

Just a thought: one of the other commenters mentioned thrust forces, and that these motors don’t use thrust washers? Just be aware that even automatic transmissions will create thrust through the stall process of the torque converter… in outboard form, the leg shaft probably runs a bearing and shim arrangement to handle thrust forces if that is the “case” (no pun intended)…just something to consider…btw, supposedly those engines were rated at 300 horsepower, but they are a generation behind the Johnson/Evinrude/OMC “Fast Strike” technology with the newer port designs….nonetheless , a bad ass motor in it’s day, and the company had all kinds of performance tweaks they used (there may even be a handbook out there for racers )

[@lustfulvengance]

You're correct that the foot or gear case of an outboard does in fact have a thrust washer behind the input gear to absorb any thrust loads from gear loading. As far as I'm aware no two-stroke outboard has any real way of taking up large thrust loads. Usually one of the main bearings is a ball bearing so it can handle a small amount of thrust loading but not a large amount. To be honest if I was going to do this I would run something like a primary belt drive from a motorcycle to a gearbox and mount it transversely in the middle or the rear of a small car that way there's no thrust loads applied to the crankshaft and you could also support the other end of the drive sprocket with a bearing so that there's no axial loads placed on the crank either.

Just a thought but I've done some oddball engine to trans mating before and the best way I could come up with for the Chevy transmissions is to find an old small block Chevy crank and cut the back portion that has the flywheel flange and converter pilot in it and have the center machined out to press in a 1 1/4'' shaft into it but in your case it would be a 7/8'' shaft to make an adapter.

[@Slot_daddy]

First of all I love this build! Something you don’t see everyday. A couple of pointers or ideas, we will call them ideas since I have no experience in this conversion. 1) water cooling: as most have said the water cools the exhaust and a boat never picks up hot water it’s always fresh so No thermostat… I would get a very high volume pump. A nice big radiator and probably a 5-10 gal water tank. 2) on the transmission I’m not sure how comfortable you are with a manual transmission. But a lot of the comments are correct on the thrust of the torque converter pushing against the crank. I would suggest going with a cheap T-5 out of a Camaro or s10 (before the comments come, this transmission is kind of weak and not ideal for hot rods) but you could always upgrade to a t-56 or something that definitely could handle it. Also with an auto transmission on the older ones you’re going to need vacuum for it to shift, or electronics. The older power glides, 350’s and 400’s can be built with a manual valve body and the newer electronic ones can be shifted with toggle switches. But I would try manual for ease of control and no need to play with converter stall. It’s all done with your foot then. 3) you can adapters for people that convert motorcycle engines to cars may help with transmission stuff there too. Also watch search 2 stroke stuffing , he is doing some crazy stuff with a 50cc two stroke and I don’t remember which video but he lays out some of the challenges with efi on a two stroke. He’s a freaking 2 stroke genius and if you let him know what you’re doing he may even have some good insight on the build. I’m loving the videos please keep them up and it’s so cool to see mom jump in the comments she should be proud !

[@AaronBonBarron]

The purpose of a thermostat is to regulate temperature, as opposed to "cooling". They create a circuit in the engine that recirculates the same water until it's hot enough to open, most outboards have one for each bank of cylinders.

Greetings from Norway. U r aproching 2 stroke with a 4 stroke mindset..NICE. Grind off the original exhaust from engine and use a early 90s honda, kawasaki, suzuki or yamaha 125cc 2 stroke exhaust on each sylinder, make it 10-15 % bigger, u need 2 use a 2 stroke expansion chamber calculator. U must weld exhaust mount and water chanels ports leading to exhaust. Now u will have 2 cooling banks. High pressur water pump need it + thermostat housing. Build the originals carbs to a dual or singel intake with direct 2T oil injectors..same principle like carburetor v8 engine. Put back your reed valves. Engine block does allow for some welding for mounting a adapter plate. small fly weel for high rev with a 4 speed gearbox from a old rally car or a powerglide gearbox from late 50s early 60s.. If it turns on wrong direction use a gearbox from a rear mounted engine older porche or wv. Sorry for my bad english.. If u put a EFI on it that will be awesome and expensive. Good luck budy

Interesting project 🤔. Major hurdles to consider: -This stye 2-stroke needs reed valves to work properly. You've removed them. -This motor uses an open loop/total-loss cooling system. -This motor is designed to dump part of thst coolant into the exhaust In rotating the motor, there is a possibility that you'll create air pockets ulin the cooling jacket -thrust loads are dealt with externally on this motor. -these things run hot 🔥 🥵

Do yourself a favor and get a set of transfer punches, a lot better than spray paint, Harbor Freight has a large set. And a more accurate way to make transfer marks from a mating surface to chip board is clean the surface and use regular old house paint. Lay the chip board, I get a 3'x100' roll for 15 bucks at Lowes, on the wet paint and you get an extremely accurate transfer. A gasket punch set will help immensely when cutting out the pattern to ready it for layout on whatever metal you're using, and HF has those too, cheap. Awesome project, can't wait to see how it goes. I'm subbed!

[@171apples171]

Hey man just an idea, a BOP(buick, olds, pontiac) transmission will have a dip in the middle at the top of the bell housing. That would be perfect for the location of the exhaust. If you go w/ one of those transmissions, i think all the work you did to find center will translate to the BOP trans too, but the bolt holes will be slightly different.

[@claytoncoolidge992]

Id consider taking a crank shaft end and welding it to the engine prop shaft to be able to get the torque converter center support as well as being able to use a stock flex plate would also allow you to use whatever you are doing for the Bell housing to bolt up to and incorporate a bearing that holds the engine shaft and the torque converter in place and prevent any type of vibration or off center or unsupported centrifugal forces from taking out the front seal and pump in the transmission. You have to have a torque converter or a clutch with a special adapter that allows for the transmission fluid pump to constantly rotate as it does with the torque converter and allow you to disengage the input shaft from the engine to stop otherwise you will not be stopping unless you're brakes happen to be really really good and stall the engine. But definitely have the right idea.

[@JosephCowen-ru7up]

[@MyFabian94]

Watercooled Exhaust is pretty normal in Marine Engines, even in the big Units, meaning Cargo Vessels. Since Airflow is limited and requires much bigger ducting to cool anything effectively, and because water is freely available in a boat, everything in an outboard is watercooled, including the exhaust piping. Since the Exhaust exits into the Water through the Propeller, it actually uses the resonant frequeny and resistance of the water in combination with the expansion chamber to get its tune. So running it in open air you will have to run a far more restrictive exhaust and larger expansion chamber to get any kind of power.

[@JosephCowen-ru7up]

You made a mistake with the bolt circle , if those bolts are NOT the same distance apart on the flex plate ( and I know they are not) you cannot get the bolt circle diameter by measuring bolt to bolt , it will be wrong, I could put one hole 2 mm from the next bolt and still be in the bolt circle but measuring from that bolt to the next would be around 3 mm and not 3.5 inch , my point is to get the correct bolt circle measurement you need to measure centre of circle to centre of bolt hole !

[@twoeightythreez]

I have an idea for your spacer, just get an old flywheel (manual transmission) and have a machine shop cut the middle from it. This will ensure that all the holes are perfectly straight and you also will get a nice thick register for the converter nose to fit into, and will cost you a LOT less than having them set up to drill all those precise holes.

[@eddiepatterson5025]

That would be a good solution to his situation

[@michaelcosbar9905]

A pretty important point... Rotating balance! That extra hole in the flex plate is for balance to the engine. If you don't have correct crank shaft balance, this thing will shake itself to death.

[@haleyy68]

I have built several of these V8s over the years. They have a rubber balance dampener on the crankshaft. Adding the massive extra weight of a full converter will not only not balance correctly with the rotating assembly but the lower main ball bearing on the crank was never designed to the massive lateral loads of a converter full of fluid being turned at RPM. Will never last for more than a few minutes at any moderate RPM

[@JosephCowen-ru7up]

A two stroke v8 90 deg motor is neutral Ballance , Ballance on American V8S was added for cost reasons as dynamicly balancing a mass produced low cost V8 and fitting it inside the crankcase was too much so they got external Ballance on some motors IE flywheel and balancer.

Just some food for thought about engine orientation. With the intake plenum being on the bottom, I'm afraid you're going to have a lot of fuel falling out of suspension and pooling down there. I think you'd be better off pointing the cylinders down and using downdraft carb(s) on top. Two strokes down care if they're upside down or not.

Sooooo. A few things. This is a 2 stroke. It can run either direction. And as there is no oil pan you can indeed run this right side up with the intake on top. You will need to premix the gas and oil. You havent figured out what direction you need to rotate the engine for the trans to work with the diff... Also you can run it with the flywheel to the rear but then the exhaust is going forward. But that's not a huge deal. Hope that helps...

If you’re having trouble getting your welder to work like you’re doing this is just a hack it’s not a recommended way to do it but if you heat up the plate a couple hundred degrees with the propane porch it’ll help the weld burn in but you definitely need to invest in a much heavier proper extension cord the cheapest way to do would be to buy a roll of the proper gauge cable and put the ends on it yourself

This is a cool idea "it's so crazy it just might work!" One thing to think about, the boat motor combines the cooling water with the exhaust usually... But at what point? Hopefully you can intercept the cooling water before this point so you can keep the coolant pressurized (typ liquid cooling in car). The openings in the motor housing, the front one would have been for the shift rod. Some exhaust would go down with the drive shaft - some of it goes thru the gear case both for some cooling of gearcase and also keeps the hub free of silt and sand. Keep 'er going

[@nkuntroll247]

Actually the through hub exhaust creates a vacuum for the exhaust once underway. This helps the motor run at RPM. The exiting water is mixed with exhaust mainly for noise reduction but cooling as well.

[@DonziGT230]

When doing something like this it would be worth the time to find out how the cooling system works in the normal application. Pretty sure that hose is for flushing the engine, and it's likely feeding it in reverse to back-flush the system so you probably want to flow the coolant opposite of what that connection would do. But since the motor will be laying down there might be other things to consider to make the cooling system work well. Also, the stock system dumps all the water through the exhaust, you'll have to figure out if the aluminum housing can handle the exhaust temps without water.

[@600wheel]

Hey man when you’re putting a transmission on an engine you generally have to be within .005” of centre so your best bet would be good an transmission swap plate that fits on your transmission but is also big enough to cover whatever mounting holes you need to hit on the motor and then get a machine shop to drill it out for you you will save in the end on clutches bearings and transmissions and just aggravation. Once you weld it on that piece that is centre where the pilot bearing goes you pulled it and changed it even if it slides right back on you still changed it and how are you sure that it is coming out perfectly in line with the shaft

[@chehystpewpur4754]

i just want to say one thing for you. as i like this project. before you go all out on your transmission adapter. your going to need to gear it down before going into the transmission. most transmissions have a safe rpm range. american ones have lower rpm limit. euro cars rev higher. these engines rev very high and that will basically melt your transmission in minutes. the bearings cant handle the rpms. the honda s2000 had to have a special transmission because it reved near 10k rpms. it may be a good idea to use what you can from the original transmission to gear it down maybe unless thats just gonna make it spin faster but youd get to keep some of your exhaust youll need. you could just do a chain input shaft or reduction drive or whatever. even a 2 speed transmission could help. some big trucks use things like that to get a whole nother set of gears. just some ideas so you dont have to do it twice.

Keep working it out. With careful thought and patience it will come along. As far as that plate going behind the flywheel goes, it’s going to have to be perfectly dimensional in order to be balanced so you might want to get some wider plate. Everything you ad has to be precise in that situation. Like you said, any wobble will cause it to beat itself to death.

[@johndenton5555]

The coolant may not be a loop like car/truck engines, most marine engines run cooler than automotive engines, and the water pump usually pulls water into itself, through the intake, and the block, and exhaust, then it dumps into the exhaust stream and it is blown out via the exhaust ports usually at or below water level.

Maybe this will help you out next time but in fusion 360 software you can upload a image. You can clean the outer rim and paint it white to give it contrast then take a picture. With the pic upload, you can size it to the correct size. Then just go through tracing your part and adding holes.

Enjoyed this very much, good improvisation! Wonder if you will have any low down torque and also if the gearbox shift will be upset? We shall see!good luck

[@him89]

Mount a under trimmed plate maybe octagon or hexagon in your drill press with a bolt. Marked with your diameter of course. Turn it on low speed, angle grind to the line. Guaranteed to be centered.

Hey bro there has got to be a fabrication shop near you that will have a crop they will sell you the shop at my old company we would basically give kids the piece that you need for that just go in there and explain to them you got a KZbin channel drive up in one of the cars you have put together or got running do it on a Friday when everybody’s in a good mood because of the weekend I promise you’ll get the steel. Guys who work for a living really respect and like to help kids like you

I had twin 4 liter V8 Johnsons on by 25 ft. tunnel hull each modded to 360 h.p., they were excellent engines, be curious to how this works out.

[@smallblocktommy581]

Im excited for this project! One day youll be able to have the tools to make everything so much easier. Primeweld makes good cheap plasma cutters and tig machines

Since the boat engine doesn't have a lot of low end torque I would recommend a high stall converter.

[@hotrodderrecycler3202]

Might need to look at the welder fitting for the line feed hose. Order hose with new end gun. Hopefully the gun end assembly that is not using ink jet cartridge you can only use our crap. Get a more universal gun. That cover/shielding on the gun does block your line of sight but saves on the wallet.

[@rickmullins3052]

I dig your enthusiasm but not sure your fully aware of the task you have out in front of you. Here is some advice and food for thought. First some history. Way back in the late 60s or early 70s. Evenrude attempted to turn a outboard into a inboard. They just took a vertical crank engine and laid it horizontal. It did work sorta. Was plagued with oiling issues. This could be a issue for you too.

[@idontlikejosephjoestar7141]

Was it 2 stroke bozo

[@FSHSKainon]

Love the doing it yourself, check out the Mercuiser I/O "Couplings" various ones to choose from

[@zachjacobs6309]

I’ve always wanted to do this can’t wait to see it run

[@zackjay71]

Your going to have to have the spacer made. And balanced. Otherwise the vibration will shake your setup apart. The flex plate. When I have my engines balanced it all goes to the machine shop including flex plate. Im glad you know this. Save you some heart ache.

[@sbartasek]

I'm really excited to see what you're doing! I've had some practice with running a single carb to multiple cylinders and have had some unexpected troubles. Manufacturers have spent a LOT of time on intake manifolds, and I learned the hard way why that was a few years ago. Hope you don't have those same problems running fuel injection. I'd love to be able to offer some insight, and work with you on this to be honest. You hiring? Can't imagine what that's going to sound like, so I really want to see and hear it in person! Most of the work that I've done has been for performance on smaller engines. Motocross and hare scramble 2 and 4 stroke engines. I've played with porting, tuned pipes, combustion chambers, timing and ignition systems, and have a deep knowledge of fuel injection as I was getting ready to turbo a project car of mine that I haven't made it to yet. I DID build a 200cc Yamaha Blaster that ran with modded 400cc and stock 450cc quads, but I cheated, and used an off the shelf pipe. Also a built a 500cc version that left them all, using a KX500 engine, and a home built pipe, but raced it myself and crashed out when I clipped a tree and the handlebar got me in the chest. It was incredibly hard to start with the kickstarter going the wrong direction, and I didn't have the $ for an electric start system. Also, then we had kids, so... Maybe I should just get back to that lol

[@andrewnagle4530]

Your doing great keep up the good work!

[@hartwickperformance]

Thank you!

[@johne189]

Disclaimer - I skimmed the video and comments so am not sure how far along this is. Apologies if I'm covering old ground. But... Chevrolet "housing" drawings with dimensions are readily available. Also Chevrolet housings having a circle concentric with the crankshaft are common. Use one as a layout tool. Use such a housing and "sweep" it with a dial indicator to center housing to crankshaft. Transfer the two dowel holes and the rest is a cakewalk. Sources for the housing include manual transmission housings; pre-'63 Powerglide spacer; medium truck SAE spacer; marine adapter plate; etc. Good luck with it

[@G-regular503]

Super rad, have you had the thing running yet?

[@forwardmotion1883]

If the plate is thick enough you could take it to a machine shop that has a head surfacing machine and it can be flattened there, like wood through a planer, I used to be a machinist many many years ago

[@peterjames2004]

just my thoughts as its such an important piece buy a piece of plate and get the the holes cut out by a shop it may be expensive but worth it in the end but go for it your way

[@tat2dpom]

I think all you people watching this should donate this guy some cash nice lad and smart come on a few $$$$$

[@naileditfencingllc5463]

You need to change your gun get rid of the Vulcan the Omni pro gun. The Omni pro welder uses a euro style connection at the welder so there are options I have a Radnor Pro gun with a 15 ft lead on my 220! You can use major brand name consumables with the Radnor.

[@Jaribm]

Small ports are coolant feeds and the big port is probably the last stop before leaving the engine. Usally meets up with the exhaust in the mid section. (The part the motor was connected when you got it...)

[@matthewridgeway9250]

Pump cream cleanser through the engine cooling jacket to clean it all up. Then a big rince.

[@sharkythedog1]

Hey HP look on the internet fir a volvo with a 8 cylinder 2 stroke motor. It's got sone really good footage. As the vidro shows the part your looking at is at the bottom and it's got the butterflies for the intake. And the exhaust is very cool as well. Give it alook

[@coreymiley2914]

Man lmk if you decide to get rid of that wagon, I had a 71 510 wagon when I was 10. I'd like to find another one to build. The wagons have sold axel, the 210s and the roaster 1600 had IRS

[@markfairhall3671]

Always wanted to see something like this

[@brianreynolds1717]

the main concern I have is if you get it to run there is no thrust bearing in the engine. The torque converter will push the crank forward and destroy the block. Not sure how you would put a thrust bearing on it. some thing behind the flywheel against the back of the block?

[@Joeameturexpert]

Maybe I missed it but why are you not mounting the transmission to the flywheel side of the engine?

[@Njazmo]

Because he wants to go 100mph in reverse.

[@TheRealCCSmith]

This kid is going to do some cool shit in his lifetime 👍

[@lucky7s94]

I would have found a sheet of something to drill a hole into to fit over the input shaft and clamped it to the bellhousing, then drilled holes from the back side and traced the outline of the bellhousing There's your template.

[@65bug519]

the pump was on the main shaft of the lower unit so it was submerged all the time, outboards dump water into the exhaust to cool it and reduce noise.
