Overview

The Simrad SS175L is a 1 kW low CHIRP thru-hull transducer with a stainless steel housing and a built-in tilted element to correct for hull deadrise. It runs in the 40 to 60 kHz band with a 32° to 21° beamwidth, and it supports depth plus fast-response water temperature sensing.

Connection is via a black 9-pin connector on a 10 m (33 ft) cable, which helps when the run to the helm or sonar module is not short. The physical envelope is about 134 mm in diameter by 118 mm in height, and installed weight is 2.7 kg (6 lb).

This style of low-frequency CHIRP transducer is a practical fit for offshore runs, deeper channels, and boats that want bottom tracking with broad coverage, especially when you are not staying in shallow water all day.

Key features

• Low CHIRP operation in the 40 to 60 kHz band with a 32° to 21° beamwidth
• 1 kW power rating for compatible sounders and sonar modules
• Depth and fast-response water temperature sensing in one thru-hull
• Tilted element options (0°, 12°, 20°) to correct for hull deadrise at the mounting point
• Stainless steel thru-hull housing with a low-profile outside footprint
• Black 9-pin connector with a 10 m (33 ft) cable
• Approx. 134 mm diameter x 118 mm height; 2.7 kg (6 lb)

Variants

The SS175L is offered with different internal tilt angles. Across the range, the key difference is the tilt of the element inside the housing, which affects how straight down the beam points once the transducer is installed on a hull with deadrise.

Tilt selection is based on the deadrise angle where the transducer will actually sit on the boat. The connector style and cable length remain the same across these options.

• 000-13774-001: 0° tilted element (for 0° to 7° deadrise). This suits flatter sections near the keel where the mounting surface is close to level.
• 000-13775-001: 12° tilted element (for 8° to 15° deadrise). This matches moderate V sections where a flat transducer would aim the beam off to one side.
• 000-13776-001: 20° tilted element (for 16° to 24° deadrise). This supports deeper V running surfaces so the beam stays closer to vertical at the mounting point.

Compatibility and fit

This is a single-band, CHIRP-ready transducer intended for low-frequency operation. Confirm your Simrad sounder or sonar module supports a 1 kW low CHIRP transducer and a black 9-pin transducer connection, or the correct adapter cable for your port type.

Measure deadrise at the intended install location rather than relying only on published hull specs. A small shift fore or aft can change the angle enough to move you into a different tilt option.

Installation and setup

Installation is a thru-hull cutout with the transducer sitting close to the outside of the hull. Typical hole sizes are 95 mm (3-3/4 in) for fiberglass or wood hulls and 105 mm (4-1/8 in) for metal hulls.

Plan the placement for clean water flow and a reasonable cable route to the helm or sonar module, then bed and torque the hardware per the supplied instructions. On metal hulls, follow standard yard practices for isolation and bonding to manage galvanic concerns.
