Boat Maintenance

After several collisions with the shore, we noticed that the aluminum propeller frames were slightly bent. The team did some research and found that if we used a different grade of aluminum, we could make the frame more rigid. After using a water jetting machine to cut the new aluminum, we spent the morning replacing the 6061 aluminum with the new 7075 parts. As preventative maintenance, we also replaced the 6 bearings on each thruster.
