[CA] [CA11] RV-100 Mounting Height

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Jack,

The intent of the diagram which you have referenced is to provide you with some guidance addressing where to drill your screw holes with respect to the elongated holes within the mount. When the transducer mount is installed using the supplied template, the screw holes which you will drill should be in the middle of the mount's elongated holes to permit the screws to be loosened and the mount to be shifted up or down a bit following testing. As shown within Chapter 5.7 Testing and Adjusting the Transducer of the RV-100 Installation Instructions, the initial height of the middle of the transducer element should be at the same height as the hull's running surface and be parallel to the hull's running surface.
