Garmin Airmar P19 Plastic Thru-Hull Transducer, 8-Pin, 77/200 kHz, 300 W, 900 ft Max Depth, Depth and Temperature, 30 ft Cable

Overview

The Garmin P19 is a plastic thru-hull mount transducer with an 8-pin connector that sends traditional sonar at 77/200 kHz and reports depth plus water temperature. It is rated at 300 W with a maximum depth of 900 ft, and it uses a 30 ft cable for routing back to the sonar module or chartplotter.

This is a low-profile, nearly flush install that leaves about 5 mm of the housing outside the hull, which helps reduce drag while keeping a clean look below the waterline. The internal tilted element is built in, so you can match the transducer to your hull deadrise without adding a fairing block.

Key features

• Traditional dual-frequency sonar: 77/200 kHz with 45°/15° beamwidth
• 300 W transducer power and maximum depth rating of 900 ft
• Depth and temperature sensing in one thru-hull unit
• Low-profile housing with about 5 mm extending outside the hull
• Fixed-tilt element options to match common hull deadrise ranges
• 8-pin connection and 30 ft attached cable for straightforward routing
• Right-angle cable exit to help in tighter bilge spaces and reduce the chance of damage when stepped on
• ABYC H-27 compliant housing

Variants

This product is offered in multiple tilt configurations so the transducer element can sit closer to level after installation.

The tilt angle and supported hull deadrise range vary by version. Other core specs remain consistent, including 77/200 kHz operation, 300 W power, a 30 ft cable, and depth plus temperature reporting.

• 010-10218-21: 12° tilt, intended for 8° to 15° hull deadrise. This range fits many moderate-V installations where you want the sonar beam to point straight down without adding a fairing.
• 010-10218-22: 20° tilt, intended for 16° to 24° hull deadrise. This option suits deeper-V locations where deadrise at the install spot is higher and the element needs more compensation.

Compatibility and fit

This is a thru-hull transducer meant for fiberglass and metal hulls. It is not intended for wood hulls. The connector is Garmin 8-pin, so the mating port needs to be an 8-pin Garmin transducer input or a compatible adapter setup.

Because tilt selection is based on the deadrise where the transducer actually mounts, measure the angle at the install location rather than relying on a general hull spec. For best readings at speed, mount in clean water flow forward of prop wash, strakes, and other turbulence sources.

Installation and setup

Thru-hull installs require drilling the hull and sealing the housing properly. Allow room inside the bilge for the hull nut and for routing the right-angle cable exit without kinking the cable. An included rubber washer can help when tightening the nut against slightly irregular hull surfaces.

Electrical and sonar integration

The P19 is a traditional (non-CHIRP) transducer, intended for standard sonar operation at 77/200 kHz. It does not add ClearVü or SideVü style imaging. If your display or sounder uses a different transducer connector family, confirm the required adapter before installation.

Use on board

This setup is a good match for boaters who want a low-profile thru-hull with depth and temperature data and who run at cruising speeds where clean-water placement matters. It also works well for sailboats that want a flush install to keep drag down around the keel area, as long as the deadrise at the install point matches the selected tilt.

Maintenance and care

Inspect the thru-hull sealing area during routine haul-outs and clean marine growth from the face to keep readings stable. Check the cable routing for chafe and keep the connector area dry and strain-relieved inside the boat.
