If you have a bulkhead (marine speak for "wall") handy to the cockpit
you could cut a hole and mount the 545 there using an optional flush
mounting kit. Then you could just put the sun cover it when you are
done for the day. But, if there is a risk of it being stolen because it
is more visible, that might not be a good idea. You can download the
flush mount template here:

and the flush mount kit is here:

On some of the flush mounts you can quickly release the GPS from the
mounting frame by releasing a couple of clips from behind the panel
(inside the boat?) and that would allow you to remove the GPS. If the
sun cover snaps onto the mounting frame, that would let you cover the
hole when the GPS is removed.

Another choice might be to have an weatherproof and capped intermediate
connector mounted in the cockpit so you can disconnect the 545 there and
remove it.

Running a cable through a hole creates a shear point where the cable can
be easily damaged. Also, it can create a leak and is not the pinnacle
of professionalism around boats.
A visit to a Garmin dealer and/or marine hardware store might let you
look at the options.
