Spare parts for Raymarine CPT-S glue-on transducer (housing, O-ring, and pin)

This R70830 spare parts kit is specifically designed for maintaining Raymarine CPT-S glue-on transducers. It includes essential components (housing, O-ring, and pin) to ensure the structural integrity and watertightness of your transducer installation, which is performed without hull penetration.

The R70830 kit includes the following parts:

A tankAn O-ringA pinThese components are intended to replace worn or damaged parts of your CPT-S bonded depth sounder.

This R70830 spare parts kit is specifically designed for Raymarine CPT-S glue-on transducers (also called in-hull or internal transducers), which are installed without drilling through the hull.

No, this R70830 kit is exclusively designed for CPT-S adhesive-mounted transducers. Thru-hull transducers and transom-mounted transducers in the CPT-S range use different mounting systems and spare parts.

The CPT-S adhesive transducer, for which this kit is intended, is designed for use on solid fiberglass hulls (non-sandwich). It is not recommended for hulls made of wood, aluminum, or steel due to the acoustic properties of these materials.

Yes, the tank and the O-ring are crucial components for installing the CPT-S bonded depth sounder. They allow the transducer to adapt to keel angles from 0 to 25 degrees, ensuring optimal sonar performance.

The R70830 kit includes only the tank, the O-ring, and the pin. The specific adhesive required for installation or reinstallation of the bonded CPT-S transducer is generally not included and must be purchased separately, in accordance with Raymarine’s recommendations.

Raymarine recommends installation by a Raymarine-certified installer for all its products. Correct installation is essential to ensure the performance, waterproofing, and reliability of the transducer, especially for a bonded installation.

The housing and O-ring are critical components that ensure the watertight seal and proper positioning of the transducer relative to the hull. Correct installation with these parts guarantees optimal transmission and reception of sonar signals, which is essential for depth accuracy and CHIRP sonar image quality.

The CPT-S adhesive transducer, of which these parts are spares, is made of urethane. This material is chosen for its acoustic properties and durability in a marine environment.

This kit is a set of spare parts for the CPT-S transducer. The CPT-S transducer is compatible with several Raymarine chartplotters, including the Element S, Axiom Pro S, Axiom 2 Pro S (with A80490 adapter) and Element HV (with A80559 adapter).

No, it is not recommended to repair a CPT-S transducer cable if it is cut or damaged. Cutting the cable would significantly reduce the fishfinder’s performance and void the warranty. If damaged, the cable must be replaced.

Using genuine Raymarine spare parts, such as kit R70830, is recommended to maintain the validity of your product's warranty. Any unauthorized repair or use of non-compliant parts may void your warranty.

To clean the CPT-S transducer, use a soft cloth and mild household detergent. If the fouling is significant, you can use a scrubbing pad such as a green Scotch Brite™ pad, ensuring not to scratch the transducer surface. Never use aggressive solvents like acetone, which could damage the transducer.

Yes, to prevent marine growth buildup, you can apply a thin coat of water-based antifouling paint to the CPT-S transducer. It is recommended to reapply this paint every 6 months or at the start of each sailing season. Never use ketone-based paint, as it may damage the transducer, nor spray paint, which can introduce air bubbles and impair transmission.

No, the R70830 kit is a spare parts set and does not include the complete CPT-S transducer. It only includes the tank, O-ring, and pin for maintenance of an existing bonded CPT-S transducer.

The CPT-S adhesive transducer, for which this kit is intended, offers a depth detection capability up to 183 meters (600 feet), enabling efficient seabed exploration.

The CPT-S adhesive transducer uses a single high-frequency CHIRP sonar, centered on 200 kHz, with a 25° conical beam. This technology delivers detailed sonar images and precise detection.

Yes, it is essential to always test and use the transducer only when it is submerged in water. Operating the transducer out of the water can cause overheating and irreversible damage.

The main advantage of a through-hull-less transducer like the Raymarine CPT-S is that it does not require drilling the hull, which preserves the boat's structural integrity and simplifies installation. It is ideal for solid fiberglass hulls and delivers excellent sonar performance.
