Similar thing happened to me last year except my shaft just sheared while driving, right were it exits the yoke of the v drive. There was a collar on the shaft that kept it from flying away. So i still had all of the shaft not to mention the prop. Once i took it apart i put the two pieces together and i had a starting point as to which length i needed. You will also need to know the diameter, i think 1 inch and 1 1/8 inch are the standard (I could be wrong, Ive tried to forget). If you still have part of the shaft this wont be a problem. As far as length goes you will have to measure from the inside of the yoke to outside your strut on the bottom of the boat. When I went through this it was easier than what you've got ahead of you. The guy at the prop shop will be great help to you as he was to me. He told me that when the prop is secured to the shaft it should only be about 1/2 to 3/4 inches away from the strut. Dont forget to account for the threads as this will make the shaft longer for measurement purposes. This should help you in determining a length. For your prop problems, i am no expert but i bet a lot of people on this site can recommend a prop. Once you know what prop you want, i recommend going to a prop shop with your boat and have them help you find the dimensions you need, and then order the prop from them in good faith. You can order the prop shaft yourself and chances are they can help with this too. I think mine was $180ish. Your local boat dealers should be able to help with this as well. If you could find the specs for that shaft on google somewhere that sounds ideal. Keep callin everybody, boat dealers, marine mechanics, part shops, ect. I know i didnt need to have a shaft fabricated so i doubt you do.
