Spacer kit for mounting RealVision 3D RV-100 transom-mounted transducer on Jack Plate

The Raymarine A80482 spacer kit is designed to optimize the installation of RV-100 RealVision 3D transducers when mounted on a jack plate. Its primary function is to position the transducer laterally at an adjusted distance from the propeller and the jack plate mechanism.

Using the A80482 spacer kit offers several advantages:

Reduced turbulence: It moves the transducer away from the propellers, minimizing wake and cavitation that can degrade sonar readings.
Performance optimization: By reducing interference, it helps produce clearer and more accurate sonar images.
Mechanical clearance: It ensures sufficient space between the transducer and the jack plate mechanism, preventing any interference during operation.

The spacers included in the A80482 kit are used to laterally offset the transducer relative to the jack plate. They create additional clearance between the transducer and the mounting surface of the jack plate, which is critical to avoid turbulence generated by the propeller and ensure adequate clearance with the jack plate mechanism.

No, the A80482 spacer kit is not a complete mounting bracket. It is an accessory used in conjunction with the RV-100 jack plate mounting bracket (reference A80480), which is sold separately. The A80482 kit provides the necessary components (extra-long bolts and spacers) to adjust the lateral position of the transducer on this bracket.

It is important to position the depth sounder away from the propeller for several reasons:

Minimize turbulence: Propellers create air bubbles and turbulence in the water (wake) that can interfere with sonar signals, leading to blurry images or signal loss.Reduce cavitation: Cavitation, a phenomenon caused by the formation and implosion of bubbles, can also disrupt the depth sounder's performance.Optimize readings: Proper positioning ensures the depth sounder is in the calmest water possible, which is essential for accurate readings and high-quality RealVision 3D images.

Yes, indirectly, this spacer kit helps improve the quality of sonar images. By enabling optimal positioning of the RV-100 transducer, it reduces interference caused by turbulence and propeller cavitation. Calmer water around the transducer results in clearer sonar signals and thus more detailed and accurate RealVision 3D images.

This spacer kit is specifically designed for the Raymarine RV-100 RealVision 3D transom-mount transducer (reference A80464). It is not intended for use with other Raymarine transducer models.

No, the Raymarine A80482 spacer kit is exclusively designed for use with the RV-100 RealVision 3D transducer. It is not compatible with other Raymarine transducer models or those from other brands.

The spacer kit is designed to be mounted on the side of a jack plate. While it is universally compatible with most jack plates, it is recommended to consult your jack plate manufacturer before drilling holes to ensure the chosen location will not interfere with its operation.

Yes, to install this spacer kit you will need the Raymarine RV-100 jack plate mounting bracket (part number A80480). The A80482 spacer kit provides the extra-long bolts and spacers to adjust the lateral position of the transducer on this bracket, but does not include the main bracket itself.

The Raymarine A80482 spacer kit includes the following items:

Four mounting fasteners (extra-long bolts). Spacers for lateral offset. Installation documentation. These components are designed for use with the RV-100 jack plate mounting bracket (A80480).

For optimal installation of the transducer with this kit, consider the following factors:

Turbulence and aeration: Choose a location where water is least disturbed by the hull, seams, rivets, or propellers.Propeller side: Install the transducer on the side of the propeller that rotates downward to reduce cavitation.Clearance: Ensure the transducer and its bracket do not interfere with the jack plate’s operation. The spacer kit helps create this clearance.Cable routing: Plan the transducer cable path to be secure and free from strain.

To minimize turbulence around the transducer, it is crucial to position it correctly. The A80482 spacer kit allows you to move the transducer further away from the propeller, thus reducing the impact of the wake and cavitation. It is also important to select a location on the jack plate that is least affected by water flow disturbed by the hull (steps, ribs, rows of rivets, strakes).

Yes, before installing the RV-100 transducer with the jack plate mount and spacer kit, you must remove the transducer from its original mounting bracket (transducer hanger) supplied with it. Keep the original parts if you plan to reinstall the transducer on a standard transom later.

It is imperative to use only high-quality marine-grade polyurethane sealants with neutral curing for sealing mounting holes. NEVER use sealants containing acetate or silicone, as they can damage the plastic parts of the transducer and its accessories.

Installing this spacer kit, like any Raymarine product installation, must be carried out in accordance with the provided instructions. Raymarine recommends installation by a certified installer, as this may entitle you to enhanced warranty benefits. Incorrect installation could potentially void your product warranty.

To ensure the spacer kit and the transducer do not interfere with the jack plate’s operation, you must verify the final position of the transducer in the water with the jack plate in all its operating positions (up and down). The spacer kit is designed to provide sufficient clearance, but a visual check is always required before finalizing the installation and tightening the fasteners.
