This will fit the 100 115 125 HP motors, but will require a different propeller, as the gear ratios are different.

Please note that this lower unit, will also fit a Force motor 1990-1997 90 HP with a 3 jaw clutch. 

We have provided this cross-reference with the resources we have available in regards to fitment. This most likely will not fit every model for the years and horsepowers we have listed. We urge you to make sure this is the exact item you need by matching the part number to what is required for your motor. If you need help doing so, please contact us prior to purchasing and we would be happy to help!
