Excellent Quality and Easy to Work With!
Size: 25FT, Color: Black+Red
I’m really impressed with the 10 Gauge Wire Translucent Power Ground Cable! The quality is top-notch—it’s sturdy, durable, and the translucent coating makes it easy to see the wire inside. This cable is perfect for all my electrical projects, and it’s been working flawlessly for powering up systems and grounding connections. It’s flexible enough to handle various setups without being too stiff. Whether you're working on automotive, DIY, or power systems, this wire is a great choice. Highly recommend for anyone in need of reliable and high-quality wiring!

Perfect for your Alpha
This kit had every single piece needed for my Alpha water pump - and many I didn't need. I guess it fits basically all the different versions out there. I remember when the single kits cost more and had much less. This is a good high-quality alternative. Stock up on them now - you'll need one eventually.

Great bang for your buck!
Swapped out my old impeller and this helped fix my overheating issue. Super high quality, fit like a glove. If you know what you’re doing it’ll take you an hour tops. Super solid for the price! Fit into my 1990 alpha one gen 1 outdrive on my 4.3 Mercruiser.
