We are in the process of replacing our original STOWE instruments with Raymarine ST60's. The ST60 manual only shows mounting options that require access to the rear of the instrument. This is a problem with the 37 Legend as the instruments are set into the Hatch Cover which does not have any rear access.We clipped a bezel off one of the ST60 instruments and found 4 holes that look like they would take 4 black self tappers that are supplied with each instrument. I am a bit concerned about taking this approach as the manual does not say anything about it. However, when balancing that against having to rip the Hatch Cover off, then re-install and re-bed it again, the "wack in the four screws" approach looks very attractive.Has anyone ever taken this approach and if so, did it work out OK?
