Perfect OEM fit
Fixed my impeller on my Mercury Salt Water 115. Best done as a two man job. Lots of videos available online .

Fits 2001 Bayliner
This product was definitely different than the original I have a 2001 Bayliner with a 3.0 MerCruiser and an alpha one second GEN drive The kit worked but the bottom gasket had a weird cut different than the original I added a gasket maker just in case (Yamaha Lube) Brand! All in all kit was fine, One thing to note is the directions that come with the kit at least for my version we’re not for the same alpha one second GEN 4 stroke kit that I got they were for a two-stroke in the pictures didn’t look the same as the parts that I had got which is fine but it’s miss leading when you send a 4 stroke kit but 2 stroke 90hp to 200hp alpha one directions! If it craps out this review will change

Super great product. Has the power and functionality to get you repairing fast!
Super great product. Has the power and functionality to get you repairing fast! Fully recommend this and it has worked great since I've owned it. Still going strong in the durability and design looks like it will keep it going strong for many years. Highly highly recommend buying this. Will work in Kuwait, Iraq, UAE, and Saudi. Good for Camps around the CENTCOM area!

Nice flexible silicone wire
Size: 14 gauge silicone wire 10ft and 10ft, Color: silicone wire red and black
I purchased to replace the main power cable for an Ender 3 3D printer. The original cables were the same type but had a cheap connector Midway through to allow the power supply to be removed if needed. THOSE NYLON connectors overheated, smelled and turned black. The BNTECHGO 14 Gauge Silicone Wire were a perfect replacement. No more connector and no more heat issues.
