Ignition button replacement
The engine kill cable on my boat froze-up. In the process of trying to get it un-stuck, the panel fractured. The Yanmar dealer was happy to supply a replacement that was not expensive. So I removed the old panel and part-by-part installed all the panel indicators and a new cable, which was not difficult. A major improvement was the addition of the gasket behind the panel, and it looks beter than the old one, which had chipped. I did have one problem in that the screw holes for the panel were stripped, so I used larger screws. The short answer for the question posed is no, you must remove the panel to get to the ignition switch.
