Lower gear ratio 135 hp

[87 concord]

Hi What gear ratio does a 135 hp lower unit have? also will it work on a 175 hp The lower unit is from a 1992 and my power head is from 1986. I am looking for 233.1 gears thank You Joe

Generally the 135 and standard 150's come stock with 2:1.

Only the high altitude 150/135`s came with 230 to 1 gears...
