crankshaft broke on generac

[yamahaulerG1]

There was a very small part of the break that looked discolored like it might have been cracked before you can see it by the hub on the right side. this motor has seen some wear and tear. before this prop I had a wood prop that broke and I had to run it about 4 miles to get home and at one point I had to cross a floating island of grass with the broken prop and the only way to cross it was full throttle and wiggle the boat across. I'm sure it all added up to the failure. Yes corky this prop is pretty heavy by itself plus my adapter and steel spacer I weighed what's left it's 14lbs. I will use the ultra prop again when I rebuild the cage because it's lighter.
