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.
