        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.
