The must do service package. This is a "fits multiple" kit so youll have some extras. The kit also includes the lower unit gear oil seals, which is awesome. I always trust quicksilver to be durable and a great value for the money.

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
