I am planning to replace the existing Raymarine 215 fixed/flush mount VHF radio on my 280DA; however, I discovered the existing hole at the helm is larger than today's VHF radios which seem to be shorter in length with more height. It looks like I need to fabricate a plate to affix over the existing hole to accommodate mounting of a newer VHF radio. Looking for suggestions around this; what material did you use and what thickness is recommended? I.E. 1/8" ABS plastic to match the VHF color, etc. Did you use silicone to affix the new plate?
Current hole (rough measurement): 7.5" L x 2.5" H. Current plate around hole/unit: 8 3/8" L x 3 5/8" H.
Looking at ICOM M324G as a potential replacement and its' radio dimensions are 7.09" L x 3.23" H.
