Tips - To determine shaft length measure from the top of the water pump to the tip of the shaft, 20 inch shaft will measure 21 1/2 inches, a 25 inch shaft will measure roughly 27 inches.

Ratio Tips - You can count the teeth of the pinion gear (the smallest gear), if it has 14 teeth, it is a 2:1, if it has 15 teeth it is a 1:87.

Bullet Diameter - Measure the diameter of the round section in which the prop slides on. (Outside to Outside) it will measure either 4 3/4 or 4 1/4. If it is the smaller 4 1/4 you will need to replace you drive with a 1:87 and possibly re-prop.

Lower Unit - Great Price

You can see when you open the box that the quality is somewhat less than the OMC on the casting and finish. Once installed, it performed excellent and the internal components seem to be spot on with precision and quality. I would purchase again without hesitation.
