    lower units

    Hi all,

    i have taken on the project of rebuilding a lower unit for a friend of mine. He has a 1994 xr6. the question i have is i can get access to a complete lower unit off a 1989 black max 200 and i think but am not sure if they are the same basic lower unit. I cant find anything on the gear ratio for the black max. any help would be greatly appreciated. thanks!

    ratio wasn`t a big deal. they are 1.78 and 1.87 which isn`t much of a difference. they were direct bolt ups.
