A while back, I obtained a Briggs & Stratton outboard motor, this motor has a forward and reverse, but there are no sheer pins, what I need to know is what happens should I hit a rock, without a shear pin, will I break a propeller? I never had a boat motor without shear pins, so I am scared to use this motor, which is a 5 hp Briggs & Stratton. Anyone know what happens if I had some thing in the water. Will I break a prop or user something else that’s going to happen, and what? I take this time to thank anyone who may be able to help me out and explained to me what will happen.
