Additional Info

This lower unit does have a 1.87:1 gear ratio and was removed from a freshwater engine. When we opened this up, we noticed that the gears were in great condition. There are scuffs, scratches, and chips in the paint, but this is very common in lower units. Upon our inspection, we did notice a slight bend to the skeg, but this can be straightened. There is also a small chip in the cavitation plate and on the skeg, but this will not affect the overall performance. This does not come with the propeller, or propeller hardware. This does come with the trim tab and the anode. This will come exactly as pictured. The unit has been drained of oil and this will need to be added prior to installation. Purcahse with confidence!

Driveshaft measures - 21-1/4" from top of water pump housing to top of driveshaft.
Driveshaft spline count - 8
Prop shaft spline count - 15

Fits: 1976-2005 - 135 150 175 200 HP - 1.87:1 Gear Ratio

If you have a V6 lower unit with a preload pin, it could only be used only from 1976-1988.  If you have a lower unit that does not have a preload pin, it can be used from 1976-2005.

Please note that this lower unit has a 1.87:1 gear ratio. These can be used on a 135, 150, and 200 HP motors as well, but the propeller will need to be switched out to keep you within the reccomended RPM.

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!
