I have few requests to add boat logo to the device boot up screen, like Mastercraft. Unfortunately due to trademark laws - I can't do it for you, but you as owner - are free to do that. Digole - is the manufacturer of LCD unit - has web emulator to translate image into a mono print, and has instructions on how to upload.
Before you do - make sure you have windows PC that can re-upload core SteadyPass code.
NOTE: Older unit, with smaller board - have different FW. Suggest to contact me before updating.
Newer unit, with Steadypass PRO on the PCB - use currently posted FW - on web site under "Downloads"
