Our first video on the Edelbrock marine carburetor! I've worked on these for years and they have some very unique differences from the performer and AVS series carburetors. We'll look at them in detail and talk about the tuning process for these.

Excellent info, I installed my carb but haven't fired my new engine yet. I stepped up the metering rods and jets thinking I wanted to run a bit richer, didn't realize the carb stock calibration already took into account this application. Will set back to stock before first fire.

I was getting some pretty rough running under hard braking, and as part of the diagnosis (yes, which included pressure and float settings) I had a GoPro under the hood. Fuel was sloshing out around the accelerator pump shaft, so I installed the marine seal. So, even for street applications, it can be useful.

Thanks for alerting the regular guy messing with boats. They also don't run air cleaners, instead they run a spark arrestor. Definitely don't want fuel in the bilge area as that is how boat explosions happen. One great thing about the Edelbrock carburetor is the contained float bowl area with no leak areas below the top seal unlike a Holley.

Edelbrock makes a very good marine carburetor for sure.

Hi, I installed a 1409 marine carb on my classic wood boat. Starts fine and I feel like to have it tuned close but it will not run without the choke at least being partly on and won't idle below 1000 rpms with out shutting down??? Any ideas. Thank you

@elvisd6691 9 ай бұрын

Great video. Just bought an Edelbrock 1409. Do you recommend that I get a Edelbrock 8190 Fuel Pressure Regulator and Control as well? Or is this plug and play? Would like to keep fuel pressure at 4.5psi

@MuscleCarSolutions 9 ай бұрын

Always always always use a pressure regulator. The 8190 works well. 4.5-6 is your pressure range to work within.

@nedsmith3659 10 ай бұрын

Greetings, I have the 1409 carb on both of my inboard boats with 351w. they both used to start on the fist bump when the engine is warm. Now both require about 4-5 rotations to start up now, could this be caused by the crappie gas now?

@MuscleCarSolutions 10 ай бұрын

Could be a number of things. Heat soak in the carb. Low fuel/pressure.

@02yamahar6lover1 Жыл бұрын

Is there any chance you can address how to set the mixture screw on these?! I bought a new to me boat and the mixture screws we’re only turned out a half turn, it would fall on its face at around 3k rpm. Turned them out a turn and a half and it runs better but can be hard to start and starts cutting out at 4200rpm.

@MuscleCarSolutions Жыл бұрын

Once you get past 1000 rpm, the idle circuit gets bypassed and the carb operates through the main metering system. Get a calibration kit and start tuning through that kit.

@norcal8718 10 ай бұрын

What about at altitude? The lake I ride my boat at is at 6000 feet above sea level, do you have any advice for that adjustment?

@MuscleCarSolutions 10 ай бұрын

Mostly the same as an automotive application. I did a video on tuning at altitude. Same basic rules apply.

Great Video! Would you use a marine 600 cfm (1409) on a Cadillac 390 or a 750 cfm (1410)? Currently have a 750 but feels like its a bit much for the old 1962 Caddy. Thank you

@MuscleCarSolutions 10 ай бұрын

Depends on the prop speed and the engine RPM.

@awardsworth 10 ай бұрын

These old engines should not run much over 3000 rpm's and have a pretty big prop pitch. Does vacuum or mechanical secondary make a big difference when applying power? Meaning is it dumping more fuel in than it can use?? Thank you so much, been looking for solutions for a while.

@MuscleCarSolutions 10 ай бұрын

@@awardsworth it’s a matter of preference and what the combination is. I’ve had excellent luck with both. If it’s more of a milder application, and that low of operating RPM, I’ll usually suggest the 4160 marine carb. A bit easier to tune as it’s not being asked for a ton of rpm or prop load.

@chief4343 Жыл бұрын

I am confused, you stated to start around 12btc, my 1982 mercruiser 260hp 5.7L calls for 8btc, I spoke with a boat mechanic who said because fuels have changed, I should set my timing to 4 0r 2btc, does this make any since?

@MuscleCarSolutions Жыл бұрын

Makes no sense. But retard the timing back that far and see how it runs.

On a marine Edelbrock carb? No. Throttle shafts aren’t sealed.

The pump seal is to keep water (moisture) out.

@lawrencebarnes6893 Жыл бұрын

The only thing I did not like about my Edelbrock Marine carb was that I had to drill and tap for the PCV valve that my 1971 Chrysler 440 certainly had since it was new. Why does Edelbrock think "Boats don't have PCV valves"? They certainly do, and it's not a great User Experience to drill into a brand new carburetor.

@MuscleCarSolutions Жыл бұрын

Boats don’t have PCV valves. Go google that. Marine carburetors do not have PCV systems. Any USCG approved carburetor does not have any PCV port, or rear port for a power brakes, or other vacuum ports.

@@MuscleCarSolutions I don't need to Goggle it. I can go look at my factory original Chrysler 440 Marine Engine, and it has always had a PCV Valve since 1971. The 440 Marine Engine Manual lists a part number for the PCV Valve.

@@lawrencebarnes6893 doesn’t really surprise me if that’s accurate that mopar got it wrong. 😆 But I can tell you no coast guard approved carburetors have PCV or any other vacuum ports, which to go back to your original complaint, is why Edelbrock doesn’t either as it’s a USCG approved carb. None have them.
