MerCruiser Engine Panel

This is a replacement for some 50 year old boat instruments. This was on a 1968 Larson All American 18 foot boat.

The one picture shows the ribbed plastic with a brown frame that was the original panel. On my print, I used a white filament, with a black border. I kept the scuppers in so that the water would drain out of the panel.

The instrument panel in the boats isn't cut well, or consistent. You may need to trim some of the wood and fiberglass to get a good fit.

The frame will look best with supports. The center parts won't need any supports.

I put in a 100K pot in the back of the boat connected to the cylinder that indicated where the motor level was. Then connected that to a Arduino Pro Mini to run the servo that adjusts the display. Remove the spring that comes with the display, the server will indicate positive position. The original screws will work.

The software will need tweaking to match the arm connected to the pot and the motor indicator.
