Alpha gen1 ratio
 
Hello All,
I have to replace a outdrive for a friend its got a 1.8 ratio, I found the same drive but its got a 1.9 ratio. This boat has a 3.7L can I use the 1.9 ratio drive and buy a bigger prop?

Don't remember seeing a Alpha 1 with a 1:90 ratio, have seen a 1:98, in any case it will work

Do make sure its not a Gen 2

As I recall, there was a 1.84( which was used with the 470) and a 1.98
which was used with the 120/140
