- Completed: 15 March 2018
- Cost: $561.98
The Raymarine EV-1 Sensor Core installation manual recommended mount requirements allowed for above or below deck installation; and horizontal or vertical mounting. The key criteria that needed to be met was the unit must be level within 5º of pitch and 5º of roll and must be mounted with the LED ‘arrow’ on the top of the unit pointing towards the vessel’s bow and must be in parallel alignment with the longitudinal axis (centerline) of the vessel. The only practical mount location on Indra was the forward center-line of the dodger hardtop.
While the supplied horizontal mounting template identified the locations to drill the mount screws, it did not identify the recommended location of the 7/8-inch hole to drill for the SeaTalkng cable pass through. When we drilled the hole for the SeaTalkng cable it was not exactly centered and therefore we had to elongate the hole for the cable to fit through the hole.
As the wood chips in the picture below reveals, the dodger hardtop at the location the cable hole was drilled was made of less than 1/2-inch plywood, coated both sides with an unknown white paint - was surprised and disappointed not to discover a layer of fiberglass cloth or epoxy resin. The newly installed dodger hardtop by the POs was not as robustly built as assumed.
The SeaTalkng cable was passed through the hole and routed aft to the overhead navigational instruments location where the cable connected to the SeaTalkng communication bus.
The Raymarine EV-1 Sensor Core part number E70096 serial number 0541202 ($532.99) is shown mounted in the dodger's hardtop and was attached to a 1-meter SeaTalkng spur cable part number A06039 ($28.99).
