Outboard is Cooling
The repair kit arrived on time as scheduled. The kit contained everything needed to replace the Mercury 175 OptiMax impeller. The engine is cooling now and we are back on the water without issue. Easy replacement.

High-Quality 12 AWG Silicone Wire — Perfect for Battery Projects
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
I bought the BNTECHGO 12 Gauge Silicone Wire (10 ft red and 10 ft black) to wire my battery power box, and it has worked flawlessly. BNTECHGO wire has always been reliable for me, and this set is no exception — very flexible, durable, and easy to work with. I’ve purchased numerous other gauges and colors from BNTECHGO, and I continue to be very happy with the quality. I would definitely buy again.
Important Note: The amperage rating depends on your wire gauge and your specific application. Make sure to size your wire appropriately based on the current requirements of your project to avoid overheating or damage.
Potential Uses:
Wiring battery power boxes or DIY power systems
Automotive, RV, or marine electrical projects
Solar panel or off-grid power setups
Ham radio or portable electronics wiring
LED lighting and audio equipment wiring
Hobby electronics and custom projects
Key Features:
12 AWG stranded tinned copper for excellent conductivity
Silicone insulation for extreme flexibility and heat resistance
10 ft red and 10 ft black for positive/negative wiring
High-quality, durable construction for long-lasting use
Flexible enough to route through tight spaces without kinking
Resistant to high temperatures, abrasion, and bending
Disclaimer: This review reflects my personal experience only and is not professional electrical advice. Always follow proper safety procedures and ensure your wire is properly sized for your application’s voltage and current requirements.

Very high quality for a fair price!
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
I just can't say enough good about this wire! It's really high quality stuff, so much so that I was impressed enough to write another review and buy more! Yeah it's really that good considering you don't see this type of wire around much. Good stuff!

Top notch quality copper and cold flexibility.
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
This is what you need for most 13.8 Volt power pigtails on portable ham radios. They will safely handle over 200 watts in most applications and the wire is flexible in the cold. I have set it outside as a reality check when it was 18.3F degrees and it flexes essentially the same as at room temperature. The copper itself is very fine strands and will likely never fail from normal use flexing. It solders easily with my 40 watt soldering iron. I will not hesitate to buy more if I need it.
