A few months back we came across a 2015 thesis targeting preventing outboard motors and stern drives from breaking off and flipping into boats when striking submerged objects:
Boat Propulsion Impact Relief System
College of Engineering and Applied Science
University of Cincinnati
Mechanical Engineering Technology

We congratulate Mr. Frizzi for choosing his topic in this field and are glad he was at least partially influenced by our site, even if it was probably later on in his project. However, his work was based on several incorrect assumptions, reducing the contribution he could have made to the field of propeller safety.
Again, we really appreciate him choosing propeller safety related topic, but want to use this opportunity to again encourage anyone choosing a student project off our list to contact us for some guidance. We definitely do not want to take over your project, but we can help point you the right direction, point you to some great resources, help you be successful, and help your work make the largest impact possible.
