1971-1979 - 40 50 60 70 HP - 2 & 3 Cylinder

This unit interchangeable with 1980-1986 and 1987-1997 models but different housing on this one (rounded cavitation plate on this one). This will not fit the 65hp 3 cylinder engine.

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!
