MerCruiser Engine Panel

This is a replacement for some outdated boat instruments dating back 50 years. Originally used on a 1968 Larson All American 18-foot boat, this setup has been revamped using modern technology. The single image shows the ribbed plastic with a brown frame that was the original panel. For my print, I chose a white filament with a black border to give it a sleek look. The scuppers were left intact so water can drain out of the panel without any issues. Boat instrument panels often lack precision and consistency in their cuts. It's not uncommon for users to need to trim some wood and fiberglass to achieve a perfect fit. Adding supports is recommended for the best appearance, especially for the frame. However, the center parts may not require any additional support. A 100K potentiometer was installed at the back of the boat, connected to a cylinder that indicates the motor's level position. This information is then transmitted to an Arduino Pro Mini, which controls the servo responsible for adjusting the display. To work properly, remove the spring that comes with the display; it will provide positive positioning feedback without any issues. The software may need some adjustments to match the arm connected to the potentiometer and the motor indicator for optimal functionality.
