so how many people really run a marine carburetor on their float.

Between my dad and myself we have four marine carbs and two automotive.
The two automotive carburetors are on the open engine jet boats.
If the engine compartment is closed, it simply must have ALL of the marine equipment.

My gramps has never run a marine carb. Neither have I.

I echo what GT Jets said. A closed compartment gets as much "marine" as possible.

On our ultra we are. Everything else is a C And J deal

You can buy the j tubes and install them yourself

Just so you know, that does make it an approved "marine" carburetor. It just kills the engine in the event of a bowl control issue.
A marine carburetor also has sealed throttle shafts.
Unless it has an "SAE marine" tag on it, is not marine.

Yep very true, but j tubes pass the visual 😆

I have never accidently fired my .45 caliber Kimber either, but I still use the safety.

Just meaning that I don't run a marine carb.

Lol my 9mm doesn't even have a manual safety. We do also run open compartments. It's just the way I was taught he's been running em since the 60s never had any issues even ran em on the race boats.

Like I said. On an open deal, I think it's fine.
As soon as you go closed compartment, you simply MUST use the marine equipment.
Simply not worth it.

Between automotive and marine
The stuff i've looked at. All seem to have spark arrestor screens built in. Like Starters, alternators, distributors are sealed.
IDK what the stuff is with the carb
OH and they have that J number that means its approved. I would assume in the event of a fire, if insurance didnt see the marine approved equipment i would assume they could deny the claim. But i dont know for sure

To be an approved apparatus, it must, at one point, have gone through testing. I order to have met the criteria set forth by UL, the EPA and the USCG.
The point I was trying to make is that adding the 180° vent tubes does not make it a marine carburetor. Only the UL testing and certification process can do that.
I have worked on USCG passenger vessels (aka party boats) and they take it pretty seriously.
It has a little to do with insurance coverage, but more to do with the EPA and the manufacturers liability coverage.
We do live in America where it is literally legal to sue anyone. Pretty much for any reason.

Not be a troll but if you burn to death in a fire on a boat that's just natural selection

Here's the deal.
And maybe this will help you guys understand why I stress it so often.
About 1996 or '97 I was on a vacation with the family at Lake Shasta.
It's July, about 115°F and we're waiting on someone to come down from parking the trailer at the dock near the launch ramp.
The dude next to us has his kids, wife and dog in the boat, he goes to start the engine and kaboom.
The engine compartment cover (doghouse) blows out of the boat in like ten pieces. The flames roll out of the boat like a breaching whale.
Have to admit, a drop of piss came out. The little girl sitting next to my side of the boat was screaming, her hair caught fire. I threw water on her and the flames quickly went out.
After emptying three fire extinguishers we got the boat out too. The damage was not all that bad.
The cause?
A non marine electric fuel pump without a safety switch and a chrome automotive alternator.
When the Ranger came by, we told them what happened while he filled out a report. He was cool as a cucumber and when asked, he said it happened about a dozen times a year.
I'm not saying anybody died, but think if it happened 40' forward at the fuel dock. I probably wouldn't be here to tell you about it.
Be mindful that what you do is fine, right up until that one time does happen and innocent bystanders get hurt, or worse, from your shortcut.
You will have to live with that. Make sure it's worth it is all I'm saying. As for me, I'll keep doing what I'm doing.
I have told this story numerous times and just typing it just now caused goosebumps. It was nearly 20 years ago.

Not sure if anyone is on PB but the end of last summer there was a jetski competition the Chanel and night. One of the bystanders recording the show caught a hatch exploding on a boat across the Chanel. You can see flames 8 ft high and the hatch go 20+ ft in the air. The guys boat that caught high was is on PB, he had two kids on the rear bench that both were on fire... Now that I think of it I'm not sure how that ended up.

I have seen the screens in the alternators. I haven't taken anything apart to look at it. I understand the need and the certification, I was mainly interested in the physical difference.

By definition it eliminates the chances of fuel leaking out of the carburetor.

If it's the same one I'm thinking of, I want to say I heard that someone dunked the kids to put the flame out. Still had some severe burns. Bad deal all the way around.
If my memory serves me right, seems that was the same weekend of the head-on boat accident just north of the Needles bridge, right about dusk.

The J-tubes?
Here's what I know being exposed to marine carburetors for decades.
If you put a regular carburetor next the same model marine version the differences are pretty subtle.
The J-tubes are to dump overflow fuel from the bowls down the throat of the intake killing the engine. A regular carburetor would be Niagara Falls all over the intake.
The throttle shafts are also different, they have seals on the shafts in the throttle body.
Another difference is the throttle lever and return spring, the lever has fewer attachment points and has a stronger throttle return spring.
Most of them have off road style "loaded" floats.
Many of them, especially Holley, have another port that allows the secondary fuel pump diaphragm hose to be attached to the carburetor. Again, killing or flooding the motor in the event of a fuel pump failure.
On electric choke models, the choke actuator is sealed with a gasket and the shaft has a seal of sorts.
More often than not they have a flare fitting on the inlet and not a barb. This is to be hard piped to the pump with steel (or stainless steel) tubing.
The only other thing out of the ordinary is the "SAE J" tag. Which is supposed to be clearly visible. Often a bright color.

Run a piece of hose from j tube to j tube and you got it!

Those tubes are vents, if u simply connect them with a hose it cannot do its job which is to vent.

I was at Nautical inn that night. We heard the ka-boom and later heard what had happened. Is there video of this?
