Spotted one of these when looking at a cottage for sale....except it was a Evinrude. Had no idea what it was till I watched this video. I'd love to have it....but my wife would kill me.
I grew up in the keys. My parents were Johnson dealers and we got one of these. We were able to add a 10' extensions onto the hose so we has 35' of hose. We used it for diving on the reefs, coral heads and channels. We were able to stay down for 50-60 minutes on a full tank of gas. Sure brings back memories seeing this video.
@@AlecPeirceScuba_SeaHunter I hate to guess hour many hours of use I have. There were three of us that took turns using it over 5-6 years from school letting out (End of May) until Labor day. Our parents owned a marina on the water and we had the use of a boat anytime we wanted to go out, and we did, a couple of times every week. We may not of been diving every time we went out, but you can bet during lobster season we were under the water. :-) Growing up in Key West during the 60's & 70's was great.
I am amazed Alec, I have never seen or heard of that type of equipment before and I have been around the diving scene since the late 70's...thanks for shareing..... Roy U.K .
Hey Alec.. thanks for the redirect. I was 12 in 67 in Victoria, British Columbia..and I didnt even know how to swim until that year. Those Air Buoy's look way cool. I just bought this Brownie, used with low hrs, but still demanded a hefty price. Today is our first trail run. We are both certified divers, and have metal detecting for 40 yrs, intending to do underwater metal detecting this round. With exceptionally hot weather this summer, I bet people are loosing jewelry like crazy in the water. Hookha is a very cheap and effective way to dive shallow water. Ditching the BCD and tank, in exchange for lots of weight's in a backpack.(7mm wet suits). Will keep you posted as to how the first dive turned out. Thanks for your encouragement and kindness. All the best to you.
I'm really tankful, because you take us back in time, you share so much with us. I apprechiate it so much I loved when you answered me, I guess yesterday, ... from the stone age of scuba diving.... But somehow it's true, because as I remeber, you used to took a stone with you if you wanted to dive. So stone age of diving fits so much perfect.
These videos are both interesting and educational, and I enjoy them. In the vintage videos, for example, Alec explains "oh, in those days it took you a week to earn that much." Several positive comments have been made by older people about that while I have been listening.
Like it or not, most of my life, as with any "senior" is behind me. That doesn't mean it's worthless nor that my life is over. In fact, all that experience is really handy in a crazy world like today! Take care. Alec
I'm happy that i have my modern scuba tank, but toys like this device are very special and i think its very funny to dive with an equipment like this, thanks for these great videos Alec!
I enjoy diving in vintage gear and I love to see others having fun with it too but when I go an a dive trip, my gear is the latest and best. Scuba is simply easier and safer today. Take care. Alec
I had one of these when I was a kid. I loved it. Fellow beach goers hated it because it's as loud as a lawn mower. Also, the air tended to have some fumes. After a few minutes of use, I'd get a mild headache. Major design flaw. Fyi: it's "aqua buoy," not "boy."
a few years ago, I restored an Aquanaut, a very fine machine that had its limitations and its design flaws, one of these is the exhaust system that was supported by the exhaust flange so breaking was evident and a better support was one of the improvements i done, another was the relief valve that was not servicable, I modified the design to make it servicable and adjustable, the bearings are standard 6206-2rs pressed over the excentrics, the engine is mainly a standard Lawm Boy D400 so with a bit of reshearch, I was able to find all parts and materials to rebuilt it correctly, the most challenging part was to design and fabricate a new flotation collar.
I have searched for and found a regular passenger car inner tube that's a perfect size to replace the float. It sounds like you've done a good job. These machines are a lot of fun and can be very useful too. Thanks for watching and sharing. Alec
I used a 8.25-20 truck tube. with a bit of constriction and a heavy duty nylon jacket, I was able to make it fit correctly. If there is a way to send you a photo, i'll send you one.
@@Zukuri620 I'll suggest you to do top quality repairs on that type of equipment as a breakdown can lead to a catastrophe a very important point is that the corrugulated hose that starts from the sleeved intake / exhaust stack and goes to the carburetor, it should be functionnal because it recuperate all the exhaust leaks and redirect them to the intake avoiding the compressor inhaling it and compress it to the diver.
Great video! I was in a jet ski repair shop maybe 20 yrs ago that had a gas power underwater scooter. Had a similar stack for exhausting and getting fresh air for the engine. Believe it was an Italian made unit. Do u have one of those? Thanks again.
It's called the Aqua Scooter. I sold mine about 2 months ago. Believe it or not, they still make them! Mine was from 1969 and still running great. A small 2 stroke engine with a prop. The gas tank was the float. I'm sure you can google it. Thanks for watching. Alec
Nice to see modern battery technology not only power my Nissan Leaf but also make hookah diving safer. Even with that long engine exhaust tube I'm still not sure I'd want the exhaust that close to the breaking air intake. If wind current changed up it would be a bad day to be sucking engine exhaust. The Brownie's Third Lung with 12V batteries makes a lot of since. The Brownie's is expensive!
We service the Brownies at our local Rainforest Cafe restaurant. They use it for diving into the big aquariums. It's pretty neat. Enough air for 2 divers to 30' and quiet - just a loud hum. Set it on an inner tube with a long extension cord for a shore dive and you're all set. Thanks for watching Jeff. Alec
Alec, I'm curious (not in that way mind you lol). Anyway - I've been wondering modern day diving we use wings and BCD's. Back in the days of black and white how did you setup without being too heavy or light weight. I know as part of my course the PADI course director got me with one breath, no fins, no air in the Bcd to kick to the surface (exhaling all the way up obviously)... This did highlight the fact that our kit makes it easier though still possible to manoeuvre with less of it.
iVlogBuzz "I'm more thinking our the kit we would see in SeaHunt, Lloyd Bridges from what I see he doesn't use a bcd." BCDs started becoming mainstream in the 1970s. Before that, divers would weight themselves based on previous experience for the amount of weight they'd need to be neutrally buoyant at a specific depth. In warm water, diving with just a swimsuit, you'd be able to move within a fairly wide band of depths, but in cold water, with a thick foam wetsuit on (which changes buoyancy as the pressure change compresses or expands the neoprene) it was much more restrictive. At depths other than the one you were weighted for, you had to do a lot of kicking (and often hand paddling) to get around.
Okay the only reason I look this up is because somebody had one on Facebook Marketplace here in Florida. I thought it was the coolest thing. And as a side note what kind of Green Convertible was in that magazine?
Glad you like it. The magazine was 1970, Sept., Popular Mechanics, where they test the new Chevy Vega!!! books.google.ca/books?id=kdgDAAAAMBAJ&printsec=frontcover&hl=zh-CN&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false A

this is the late version, the early version have a water hose like fittings, metal compressor valves, the harness belt arrangement is different-and the carburetor is different
not for the aquanaut, the design of the aquanaut or the air buoy( the same ) is that the air is freeflowing and you thake only what you need, the rest is dumped to the water so there is no mechanics except two poppet valves at the diver level, the maximum pressure exerted at 30 feet of water is 15 PSI and the air pump is not sufficiently strong to whitstand a much higher pressure, so the relief valve setting is about 22 PSI, this kind of pressure is not high enough to permit the proper functionning of a standard second stage unless the springs and the orifices are modified and it's a job for a specialist that have the equipments to calibrate.
Sorry but no my friend. Way too many of my own projects on the go. Google the make and model to find the owners manual (free or a few dollars). It will help you with parts explosion diagrams and part numbers. Not that hard if you ever had a gas mower! Good luck. A
it is a D400 engine with 3 modifications, one is in the cylinder casting to include a flange for bolting the muffler, the second one is that the case is fitted with a roller bearing instead of a bushing and the last one is thet the end of the crank is machined 3/4" dia to recieve both compressor connecting rod excentrics, the rest of the engine is similar to the lawn mower engine.
where is the breathing air intake and engine exhaust ? seems like you take a risk of CO poisoning if the wind pushes the fumes in the wrong direction... Neat toy!
Good point Alain. I didn't make that clear. The combined exhaust/intake tube is for the engine only. The compressor intake for the breathing air is under the canopy. Still not perfect but pretty safe from CO. Neat toy don't you think? Alec
that's why it's so important to be sure that the exhaust system is leakproof and the corrugated hose that ties the carburetor to the air tube is in top shape.
