Additional Info
This specific lower unit is in great freshwater condition. We have taken the time to open and inspect this lower unit. The paint on it has seen better days, but this is purely cosmetic. The skeg is straight with only minor dings. This does come with the trim tab, but does not come with the propeller or the propeller hardware. Upon our inspection, we did notice a small chip out of the skeg, but this will not affect the overall performance. Given our unprecedented 1 year warranty on every lower unit, you will never find a better deal on an OEM lower unit.  Purchase with confidence!   

Driveshaft measures - 20-1/4" from top of water pump housing to top of driveshaft.
Driveshaft spline count - 13
Prop shaft spline count - 15

Fits: 1987-1997 - 75 80 85 90 HP - 3 cylinder models - 3 jaw clutch


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


If you're looking this up for the 100, 115, or 125 HP, you'll have noticed that the lower units are essentially identical. The difference in the 2 units is that the 100-125 HP (4 cylinder models) has a 2.0 to 1 gear ratio. The 75/90 has a 2.4 to 1 gear ratio. The 2 units are interchangeable but may require you to change propellers in order to maintain the same speeds your boat would do before. So, in short-this unit is for 75-90 HP 3 cylinders from 1987-1997. It will look and fit identically with the 100-125 HP 4 cylinder models in the same year, but the gear ratio is different. If there's anything else we can answer or help with, don't hesitate to contact. Our number is in the contact information.
