Not a jet boat, jets don't have exposed props but still super cool. Perhaps it can be made into one or just hot rodded in general. Have a great day all!
Someone with enough fiberglass experience could graft the jet pump section from a jet-ski into the hull. Fit the motor up front with a driceshaft to the jet pump.
I took one of these out at the Dells back in 1986; a bunch of us went around this huge pool - it rocked! But they definitely called them jet boats - my guess was that this was because it was a good way to advertise these crazy things; let me tell you they were scary fast! They handled really well too; super tight turns, agile, and mine was literally underwater for a few seconds from when my partner passed me and swamped me with her large wake - and it still ran perfectly.
Joe, That is not an electric starter. you wind the rope around the barrel in the grooves below the pinion that engages the flywheel. When you pull the pinion pops up like you showed. This way the kids could start is and the rope would retract and be rewound onto the barrel. Otherwise not very handy if you have to open the hood and manually wind the rope every time.
Joe, the white hose is fresh air intake for carb. You really should test condensers and coils. The cracking around the one coil suggests it’s on its way out. Intermittent spark can be isolated by keeping spark tester in inline while troubleshooting. A weak coil or condenser can be frustrating to isolate otherwise.
Hey Joe, been watching your channel for a while now...very impressed!!! I have that same motor and the mechanism you called electric start is actually the recoil starter. Just run the cord around the spiral and it will recoil just like any other outboard motor.
when I was a little kid back in the 50's and into the 60's, my Dad had a Johnson outboard motor, with a rope pull just exactly like that. I don't remember what HP it is, maybe a 5 or 7 or so, very small though. He'd take my brother and me down to Lucy's Branch, a local fishing lake, rent a John Boat for the day, stick that motor on the back, and we'd stay out all day long. VERY fond memories. BTW, I still have that motor, although it's locked up right now. This one may inspire me to go get that thing down and see if I can get it running again. Thanks for this one.
@@JohnnieBravo1 As long as you keep an intact master copy kept safely somewhere you can butcher it at your heart's content. I've yet to try it with video myself, but audio was a fun learning curve.
Imagine something like this as a single seated small car/velomobile with an aerodynamic enclosure that could do 55mph on the hwy but also be drove directly into water and used as a small boat
Love these things! I have 3 mini boats myself. (2) wooster hellions, and an aqua lark. All outboard powered (for now) got a jet ski donor recently for a swap on one I'll be starting soon. Anything in the 6'-10' range is a ton of fun!
Hello Joe I just wanted to tell you, your videos are great. There are a few things I would like to point out like most floats are not hollow and you can't shake and hear gas inside. The OMC motor here has a cork float ( like old wine bottle stoppers). Revisit that Yamaha you burried, aside from possibly flywheel key it could be a fouled spark plug. Lastly running an engine with a loose flywheel nut is deadly.
You should pick up one of those cheap, or expensive, borescopes from Harbor freight that you can stick into the spark plug hole and look around first. Doesn't always necessarily save you a teardown, but you can get them so cheap nowadays everybody should have one. Excellent for checking your piston wash as well.
That is a neat little 2cyl 2 stroke. Remember that since it is water cooled, it could have a crankcase leak (vacuum leak) between the cooling jacket and the crankcase. Fixing the goonie googo choke and throttle linkage should help everything work better.
Thats so cool. I had this exact boat when i was a kid, i paid 50 bucks for it and couldn't get it to run (being a kid and all, maybe 12 or 13) then sold it for 100 bucks a few months later. Also i lived in west Michigan. Makes me wonder if it might be the same one. Would have been at least 25 years ago
What you have there is a Johnson/Evinrude probably 9.9 or 15 horse outboard they were very popular for many different applications. The starter that you’re looking at is a recoil starter and always was a recoil starter. If you do a search for Johnson 9.9 parts you should be able to get anything you need.
Joe., This brought back so many memories of my Hydromight, It was my first boat. I was around 10 years old when I bought it from my cousin, the engine was long gone. I worked for quite a while learning to fiberglass and installing a transom for a 3.5 Sears outboard motor that I mowed lawns all summer to get. I hooked up the steering cables. Painted it white and yellow with Sears 2 part Epoxy. If anything it was probably one of my best learning projects at that age. That whole engine setup is quite different for sure.
Check if the coil plate under the flywheel can move. Most old outboards have a moveable “timing plate” that’s tied to the throttle so it advances as you give it throttle. If that’s the case, there’s a start position, run position, fast position, etc. It may be locked static on that motor to keep it from revving up high.
Lower unit is a Kort nozzle. Used on drives to more focus thrust like for sailboats with auxiliary outboards or heavy tow boats. Modern cruise ships use an improved version where the pod itself rotates vs a rudder
Just to rule everything out, there's a small aluminum disk with a dent in it on the outside of the carburetor that is a cover for a mixture screw (I believe). You can drill a small hole and remove it with a sheet metal screw. You may want to pull it and clean it out. They can get pretty nasty. You shouldn't have to replace the aluminum plug. It's a tamper plug to prevent people from messing with mixture. I believe it's probably out of warranty by now.
Joe that is cool. That forward scoop looks like a vent. There is one aft too. Air circulates through the compartment and out the back one while your moving. Removes heat and gas fumes. They should have a blower forcing air in so you can vent before you spark ignition. Just a thought. 😜👍👍
I was going to say crankshaft oil seals as there was play when you lifted the flywheel up and down, great it was something simple like the plugs, cant wait to see it on the water. Another great find , wish I could find obscure and weird things like that to mess with here in the UK 🇬🇧
We used to have one when I was a kid. My dad bought it at a boat show. It does have a round gas tank for the back We didn't wait very much for ours went pretty fast. Good luck thanks for the memory
Those old outboard engines can be an absolute pain in the butt but can be a real joy to work on at the same time. I’d replace the coils, condensers, and maybe even points. Also putting a 15hp power head in there is a great idea
That is way cool joe can’t wait to see it run on the water I hope you fit in it lol very unusual never seen one like this before look forward to the maiden voyage 😉😀 all the best have a great week 👌👍🔧🔧🔧❤️
That thing us too cool!! Dryer hose is a vent inlet for venting fumes out from inside body. Should be an outlet as well. Nice find, you 2 need to have some kiddos so they can ride some of this cool stuff. They'd have the coolest stories when they got older. 👍
I'd check the waterpump impeller if you didn't already. Seems there should be a little more resistance when you were turning the prop.. I've replaced a few I'm my day and even the worn ones were noticeable when turning.
order two coils to those cracks will let moisture in and cause cylinder to stop firing when I was younger and broke I'd put them in the oven to dry them out and get them working
That long brass shaft in the top of the carb leans or enriches the fuel. My dad had an old Evinrude 9.5 hp and sometime we had to play with the setting to get it to run right, essentially when the engine was cold. We ran it around 1 1/2 turns out.
I went in one of those in the Wisconsin Dells way back in 1986! There was a huge circular pool, and around 10 of us that went out at a time. It was AWESOME! The things was crazy fast!!!
High speed jet is in the bottom of the fuel bowl. That is a Johnson/Evinrude outboard motor. 2 Stroke! Keep running it with no oil and you'll seize it.
3 things, that is basically an old omc outboard and should have a lower unit with a propeller below the head. It looked like it was sitting flat on the trailer so maybe it is missing? The white hose is the air intake, the exhaust exits out the lower unit like a normal outboard.
That is not a starter motor. That is a recoil that would normally have a rope wrapped around it as it would be at the front of an outboard. The notches in the flywheel for the rope were for emergency use only. I had one of that arrangement. It engaged just like a starter would. I'm no expert on old outboards, but that "starter" and carb sure look like a Chrysler. They run great, but good luck finding parts.
second one of these ive ever seen. i tried to buy a yellow one in the late 80's as a kid out of a tow yard. cool you have the lower unit. excited to see how it turns out!!!!
That spiral cylinder with the Bendix should have a pull rope wrapped around it permanently, its not electric start, it should be spring loaded with a recoil spring. 🙂
What a fun little project. Amazing variety, always a learning moment, having long since stopped tinkering, still find it entertaining. Keep up the hard work, subscriptions are up, and views are up, even with the lack of 🐕 VinnyTime
Sound like running on one cylinder.. Long brass jet is slow running mixture adjustment.. Turn anticlockwise to richen mixture. Check plugs to see if they are both firing
Yes same as my motor. That is a rope starter not an electric starter. The rope winds around the twisty thing below the Bendix that engages the Flywheel
Priceless, don't want to run it to long it's water-cooled but let's start it one more time. 😂 I love it. Ur one of us ole guys too. One more time won't hurt. Will it. Keep on keeping on. Stay safe one more time.
Awesome find. This engine looks really similar to the engine in my old 62 Sea King 5HP outboard. I believe its an OMC engine. That float is cork, no way for it to fill up. They do eventually start to disintegrate, but yours looks fine. Also as you know the carbs on these engines don't have jets like most of the stuff you work on does. You need to adjust the high and low speed needles to allow more or less fuel during idle and WOT. They can take a little bit of messing with to get dialed in properly. I typically start at 1 1/2 turns out which will usually get it running and go from there.
That is it. I tried to describe one of those to a friend, but he just wasn’t seeing it. I remember renting one of those at a timeshare community down in Florida near Disneyland back in 1989. I described riding on top of it like a go kart.
I notice when you're trying to run this motor, you're just actuating the throttle and another advancing the timing. There needs to be a linkage from the carb to the timing advance, or that motor will only run the way you currently have it running
That long needle in the front of the car there should be two of them. One will be for air adjustment and the other will be for fuel adjustment. If that's all the way in you're not gonna get fuel and you're not gonna get air to run that I have a 1955 Evinrude 18 hp that is set up the same way, you have to adjust the front two needles unless yours only has one which is a long pointy needle on the front of the carburetor turned that out a couple turns or a quarter, turn and try it again
I rebuilt a 5 hp Johnson twin a couple of years ago. Your coils look shot, like mine did, bought aftermarket. Rebuilt the carb and new wires. The oil/gas mixture for mine was 24 to 1……a little smoky 😅
All that oil you put down the cylinders may have been just enough to foul the old plugs. That engine is remarkably clean for being as old as it is; the original owner must have taken excellent care of it. Great find and video! I'm sure you can fix just about any engine:)
It’s just a toy it probably has really low hours. It’s only used in the summer and you’d have to use it every weekend for 5-6 months each year to rack up hours. I doubt that’s the case though. It was probably only used a few summers. Most people don’t get out on their boats like they think they will when they buy one.
Hope you're running 2 stroke gas and a ratchet adapter on your drill will stop the bolt breaking lose when it tries to start. Fun little boat, good luck.
