Airmar 33-617-01 Stainless Steel Housing SS617v

Airmar 33-617-01 Stainless Steel Thru-Hull Housing with Valve (SS617v)

The Airmar 33-617-01 (Model: SS617v) is a heavy-duty, marine-grade 316L stainless steel low-profile thru-hull housing engineered for Airmar smart depth, speed, and temperature insert transducers—specifically the popular DT800 and DST800 series (excluding CS4500 ultrasonic and ST800/ST850 models). Designed for installation on metal, fiberglass, or wood hulls, this housing provides a secure, leak-proof passage through the hull envelope.

Features an integrated self-closing water valve flap that significantly reduces water ingress into the bilge when removing the active transducer insert for maintenance, cleaning, or winter storage blanking. The precision-machined 316L stainless steel construction prevents galvanic corrosion when installed on steel or aluminum hulls (with proper isolation) and offers superior mechanical strength against hull impact and high hydrostatic pressures.

Key Features

• Integrated Water Valve: Spring-loaded self-closing internal valve minimizes water stream entering the boat during transducer insert removal or maintenance.

• 316L Marine-Grade Stainless Steel: Cast and precision-machined stainless steel structure offers high tensile strength and long-term corrosion resistance.

• Low-Profile Hull Flange: Minimizes hydrodynamic drag along the hull running surface for clean, turbulence-free water flow across the sensor face.

• Complete Replacement Kit: Includes the stainless outer housing body, hull nut, heavy-duty rubber isolation washer, safety clevis pin, and top cap.
