750 CFM - 4150 - Vacuum Secondaries - Gold Dichromate - Gasoline
All Holley Marine Carburetors are designed to meet Coast Guard specifications. A marine carburetors fuel metering system is calibrated to compensate for unique engine loads found on boats. The J-style vent tubes direct fuel/fumes back into the carburetor for safe operation while on rough waters.
NOTES: Notice - Due to the natural color variations of the dichromate plating process, the plating color may vary from casting to casting (within a carburetor) and from carburetor to carburetor. This is considered normal and is not a cosmetic defect. If you desire a carburetor with no color variation, please shop our black and shiny finish carburetors.
Features:
- Gold Dichromate finish for corrosion resistance and classic Holley looks
- Universal Marine Calibration
- Vacuum secondaries for use on wide variety of boats. Compensate for all weights to allow smooth opening of secondaries.

UGREEN Cat 8 6FT Braided – Finally a short cable that actually hits 40 Gbps in real life

UGREEN Cat 8 6FT Braided – Finally a short cable that actually hits 40 Gbps in real life
I have a 10 Gbit NAS (Synology DS1823xs+) sitting right behind my gaming PC, and every “Cat8” cable I tried before this one was either stiff boat-anchor thick or straight-up lied about speed. This UGREEN 6 ft braided version is the first one that actually delivers.
Real-world tested speeds
iperf3 PC ↔ NAS: sustained 39.4 Gbps bidirectional (that’s ~4.9 GB/s)
Large 4K/8K file transfers: 4.7–4.8 GB/s steady, no drops
Zero packet errors after 48 hours of torture testing
Build quality & practicality
Flat braided jacket is super flexible, looks premium, and doesn’t turn into a tangled mess like round Cat8 cables
Gold-plated contacts, double shielding, and it passes a Fluke DSX-8000 Cat8 Channel test (yes, I’m that guy)
Perfect 6 ft length, no excess coil behind the desk causing signal reflections
Snagless boot actually works, no more broken clips
Why I love it for desktop use
Runs cool even at full 40 Gbps load (barely warm)
Way less stiff than the usual shielded Cat8 firehoses, easy to route under a desk or through a cable sleeve
Latency is stupid low: 0.22 ms average to my NAS vs 0.45 ms on my old Cat6a round cable
Only “con” (and it’s tiny): it’s flat, so if you’re one of those people who religiously wants perfectly round cables for aesthetics, you might not like it. Everyone else on planet Earth will think it looks cleaner anyway.
For $14, this is the best short-hop 40 Gbps cable on Amazon, bar none. Already replaced every 1–10 ft run in my office with these. If you have 10G+ gear sitting close together and you’re still using Cat6 or stiff Cat8, do yourself a favor and grab a couple. You’ll instantly feel the difference.
10/10 – UGREEN absolutely crushed it with this one.

Still the best ethernet cable out there right now
Size: 6FT
I ordered several of these cables a couple years ago and they are still the best cables I have ever purchased. The Cat8 speed rating is great. These are very well built with the outer covering and the quality connectors and covers over them. Fast data transfer wtih Cat8. I am ordering more tonight to replace some other cables as these just look, feel and work premium.

Great Cable!
Size: 10FT
Cable is great. Ive always been happy with UGREEN products. Only gave it a four star because I ordered a new cable and received a used one. Works just fine and its not an issue with the product.

Great Cable
Size: 10FT
I’m really impressed with this cable. The braided design makes it feel extremely durable compared to standard rubber cables, and it gives me confidence that it’ll hold up well over time without fraying or breaking. The 10-foot length is perfect—long enough to reach where I need without creating extra clutter.
Performance-wise, it delivers exactly what it promises. The connection is fast and stable, making it great for gaming, streaming, or anything that needs a reliable high-speed connection. Overall, it’s a high-quality cable that combines durability, performance, and a convenient length. Definitely a great buy.

Simplicitic, fast, and amazing quality
Size: 6FT
It made a big difference from wireless connection to wired connection. Definitely worth it for online gaming and casual movie nights. A good amount of thickness that doesn't tangle when installing and pretty easy to use. I would buy again for future devices. 10/10
