Raymarine SS164 1000W Depth & Temp Stainless Steel Through Hull 0° Transducer 200/50 kHz (8 pin)

Raymarine SS164 1000W Depth & Temp Stainless Steel Through Hull 0° Transducer 

Raymarine SS164 1000W Depth & Temp Stainless Steel Through Hull 0° Transducer is a premier 1kW, dual-frequency transducer designed specifically for those who need deep-water capability without the bulk of a traditional fairing block.

Crafted from premium stainless steel, this low-profile through-hull transducer sits nearly flush against your hull (protruding less than 6.35mm). This streamlined design is the ideal choice for fast, trailered, or tournament sportfishing vessels, providing exceptionally clean water flow and maintaining accurate readings at speeds up to 30 knots.

The "Tilted Element" technology is the secret to its success. This specific 0° model is designed for hulls with a deadrise of 0° to 7°. By housing the ceramic element at a fixed angle inside the low-profile casing, the sonar beam is focused vertically toward the seabed, ensuring the strongest possible echoes and the most accurate depth data.

With a 1kW power rating, the SS164 is a powerhouse. Its internal array of three high-performance ceramics makes it six times more sensitive at 50 kHz than standard 600W models, allowing you to reach depths of up to 500 metres (1,640 feet) with ease.

Raymarine SS164 1000W Depth & Temp Stainless Steel Through Hull 0° Transducer Key Features

• 1000W High-Power Output: Delivers superior deep-water performance and crisp target separation for both inshore and blue-water trolling.
• Dual Frequency Versatility: Operates at 200 kHz for high-resolution detail in shallower water and 50 kHz for deep-water penetration and wide-area searching.
• Flush-Mount Design: The low-profile stainless steel housing reduces drag and improves fuel efficiency while ensuring the transducer performs flawlessly at high speeds.
• 0° Tilted Element: Optimised for vessels with flat or very shallow deadrise hulls (0° to 7°), ensuring your sonar beam points straight down without the need for a fairing block.
• Stainless Steel Construction: Robust and durable, making it the perfect choice for installation in metal, wood, or fiberglass hulls.
• Dual-Sensing Capabilities: Provides highly accurate digital data for both Depth and Water Temperature (using a fast-response sensor).
• Plug-and-Play Connectivity: Fitted with a Raymarine 8-pin "DSM-style" connector, compatible with CP370, CP300, DSM300, DSM30, and DSM250 modules. (Can be adapted for other systems with optional cables).

Raymarine SS164 1000W Depth & Temp Stainless Steel Through Hull 0° Transducer  FAQs

What makes the SS164 different from a standard 600W transducer?

The SS164 is a significant step up in performance. It features a "trio" of high-performance ceramic elements, making it roughly 6 times more sensitive at 50 kHz and twice as sensitive at 200 kHz compared to the entry-level SS60 models. This means clearer target separation, better bottom tracking at speed, and the ability to see fish in much deeper water.

Does this transducer require a fairing block?

No, and that is one of its greatest advantages. The SS164 uses Tilted Element™ technology, where the ceramic arrays are pre-set at an angle inside the housing. This allows the transducer to be mounted nearly flush with your hull while the sonar beam points vertically straight down. It’s the perfect solution for fast, trailered boats where a bulky fairing block would cause drag or interfere with trailer rollers.

Is the 0° Tilt version right for my boat?

This specific model is the 0° Tilt version, designed for hulls with a deadrise angle of 0° to 7°.

• • If your hull is flat or has a very shallow V, this is the one you need.
  • If your deadrise is between 8° and 15°, you require the 12° version.
  • If your deadrise is between 16° and 24°, you require the 20° version.

Note: Installing the wrong tilt angle will result in a slanted sonar beam and inaccurate depth readings.

What hull materials is the SS164 compatible with?

Because the housing is made of high-grade stainless steel, it is compatible with all hull materials, including:

• • Fibreglass (GRP)
  • Wood
  • Metal (Aluminium or Steel) — Crucially, for metal hulls, you must use the included isolation bushing to prevent electrolytic corrosion between the stainless steel and your hull.

What depth performance can I expect?

The SS164 is a powerhouse capable of reaching impressive depths:

• • 50 kHz (Wide 22° beam): Effective up to approximately 549m (1,800ft).
  • 200 kHz (Narrow 6° beam): Effective up to approximately 244m (800ft).

This makes it an excellent choice for both inshore reef fishing and blue-water trolling.

Will this plug directly into my Raymarine display?

This model comes with the Raymarine 8-pin "DSM-style" connector. It is a direct "plug-and-play" fit for:

CP370, CP300, DSM300, DSM30, and DSM250 sonar modules.

For newer Axiom or Element displays, you will typically require an adapter cable (e.g., an 8-pin to 25-pin or 9-pin adapter depending on your MFD model). Please contact us if you need help selecting the correct adapter.

Can I use this transducer for water temperature?

Yes. The SS164 includes a built-in, fast-response water temperature sensor, providing accurate readings directly to your multifunction display.

How much of the transducer sits outside the hull?

Very little. The low-profile design protrudes less than 6.35mm (1/4") outside the hull. This minimal profile ensures there is virtually no impact on your boat’s running performance or top speed, and it won't be damaged by trailer bunks.

What size hole needs to be drilled for installation?

For Fibreglass or Wood hulls: A 95mm (3-3/4") hole is required.

For Metal hulls: A 105mm (4-1/8") hole is required to accommodate the necessary isolation bushing.

Can I test the transducer while the boat is on the trailer?

You should never run a 1kW transducer in "open air" for extended periods as the ceramic elements can overheat without water to cool them. For testing on the trailer, only power it up briefly to verify the connection.

Morgan Marine Expert Tip: When installing, always ensure the transducer is mounted in "clean" water—away from strakes, intakes, or propellers that cause turbulence. If you're unsure about the best mounting location on your hull, give our workshop a call!
