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! 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!

Excellent wire!
Size: 2 Colors each 10FT, Style: 10AWG
This wire is very soft and flexible. Many strands and tinned nicely. A perfect upgrade for my power wheel wires that keep melting. These have been running for months in exterior environment without any issues.
