Garmin GPSMAP Chartplotters - Hull Mount

A thru hull fitting requires a hole to be cut/drilled in the boats hull for the fitting to pass through. Garmin Hull Mount can be used to expel waste water, such as from a sink, to let sea water in, such as for engine cooling or to allow placement of sensors such as depth gauges.
