Will the Alpha 1 Gen 1 outdrive pair with a V8

[Step Up]

Awesome but how do I now what gear is in the existing out drive. It has the 165 hp 6 cyl. I found a chart on line and it has it has a 1.62

A couple of options for checking. Run the serial number online. Count the rotations of input and output shafts if it is off the boat or open the cap and count gear teeth. 1.62 is fine you will just need more prop pitch.
