1. Locating the HDR 650 Mounting Position
You must select an appropriate mounting location for the HDR 650. Consider
different positions on the console or deck of the boat, and note the following:
• The cables for the transducer and power must reach the mounting location.
Extension cables are available.
• The mounting surface should be visible to the boat operator and adequately
supported to protect the HDR 650 from excessive wave shock and vibration.
• Allow at least 2" clearance at the back, sides, and top of the unit for
connection, air flow, and ease of installation and removal.
2. Cutting the Mounting Hole
Once you have selected your mounting location, perform the following steps:
1. Mark the desired mounting location, then drill a pilot hole.
2. Drill a 2 1/8" diameter hole using a hole saw and hand drill. This is a
standard hole saw readily available for rental or purchase. If you prefer, any
marine service shop can perform this task.
