Broken prop shaft on Verado 300 , 101 hours only
I am new in the boating world and I would like to know if this has ever happened to anyone of you. I read in a forum that this is because of barking the props but from what I know and see on Youtube, rib boats are very fast, light and comfortable. Even if you are riding fast you still feel comfortable and confident riding it. But before I broke the propeller shaft, I played around with the boat at around 65 miles per hour on 2-3 feet chops of water for about 7 mins with 6 other passengers and I could feel that we were flying. The props were in and out of the water. The next day I drove around at cruising speed of 35-40 miles per hour. After a few hours, I refueled. Afterwards, I was cruising at 40-45 miles per hour when suddenly the RPM on the starboard side went up. Upon checking, we discovered that I do not have a propeller and a propeller shaft anymore.
Any thoughts on this? When we rode at 65 mph the day before, my trim was up. Do you think I stressed the propeller shaft too much?
My boat is a 10 meter rib twin Verado 300 and lower unit is 4.8 in diameter. Bravo 1 props with Flow torque 2
