Propeller shaft length is critical and must be measured correctly. To ensure
overall shaft length, measure from the V-drive shaft to the back of the strut
barrel, and add 5". Different alloys are available differing in strength
characteristics ranging from weakest to strongest as follows: 303, 17-4, Aquament 22. The amount of horsepower available should be the determining factor
in your selection of the correct alloy. We will be happy to make a
recommendation for you in this respect. Just give us a call. For a machined shaft, please purchase the shaft machining option in the related parts section.
