Size of sq. vs round command link gauges?

[sandiegosteve]

Hi,

I've currently got a round command link gauge on my boat. I want to add the fuel (2007 F115 with the hub in place) monitoring capabilities.

I may have the option to get a square one at a good price, but I want to know how big it is first... and does it use the same hole as the other gauge?


Thanks in advance,
Steve

From the installation manual they are 3.86" square with a hole diameter of 3.37". The round Command Link gauge is also 3.37" diameter hole.
