Raymarine M265LH 1kW Urethane In-Hull Transducer w/In-Hull Mounting Kit
Raymarine M265LH 1kW Urethane In-Hull Transducer w/In-Hull Mounting Kit — Product description
Discover the freedom of crystal-clear underwater imaging without compromising your boat's hull integrity. The Raymarine M265LH 1kW urethane in-hull transducer stands out for boaters who prioritize hassle-free installation and top-tier performance. Ideal for trailered vessels or those frequently lifted out of water, this transducer mounts seamlessly inside the hull, dodging the drill entirely. With its dual CHIRP frequencies, it delivers sharp resolution in shallow waters and reliable target detection at greater depths, making every fishing trip or navigation outing more productive.
Unlock Superior Sonar Performance On Any Hull
Crafted with eight internal ceramic elements, this transducer sweeps a broad CHIRP spectrum—low frequencies from 42-65 kHz for deep-water prowess and high frequencies from 130-210 kHz for pinpoint shallow-water detail. Boat owners love how it adapts to deadrise angles between 0-30 degrees, ensuring consistent beam patterns whether you're on a planing hull or a deeper V-shape.
- Deep Penetration Meets Precision: Reach up to 3,000 feet on low CHIRP and 1,000 feet on high, with beam widths tightening from 25° to 6° for focused returns.
- No-Hole Simplicity: The included mounting kit features a custom-cut tank that fills with liquid for optimal acoustic coupling, preserving your hull's warranty and resale value.
- Rugged Urethane Build: Withstands the rigors of saltwater exposure, delivering reliable pings season after season.
- Extended Reach: 33-foot cable gives flexibility for clean routing to your chartplotter or sounder module.
Effortless Setup for Weekend Warriors and Pros Alike
Installing an in-hull transducer shouldn't feel like a shipyard overhaul. Start by selecting a flat spot inside the hull forward of the running gear—ideally amidships for balanced performance. Cut the tank to match your hull's deadrise, secure it with adhesive, and fill it with the recommended non-freezing coupler fluid. Drop in the transducer, connect the cable, and you're scanning. Pro tip: Test in a water tank before launch to verify bubble-free operation and peak signal strength. This approach minimizes air interference, maximizing your sonar's clarity even at speed.
Real-World Wins: From Backyard Bass to Offshore Adventures
Anglers targeting structure in 20-50 feet swear by the high-frequency CHIRP for separating baitfish from bottom-huggers. Offshore, switch to low CHIRP to track wrecks and schools at 500+ feet. Its 1kW power output punches through thermoclines better than lower-wattage options, revealing fish that others miss. For multi-species pursuits, the wide-to-narrow beam transition adapts to changing conditions, whether trolling lures or drifting live bait. Trailered boaters appreciate the removable design—no worries about hull damage during transport.
Compared to thru-hull alternatives, in-hull setups shine in versatility: no growth fouling on the exterior, easier winter storage, and zero drag penalties. It's a smart upgrade for repowers or sounder swaps, breathing new life into older electronics.

Frequently Asked Questions
What makes the M265LH ideal for trailered boats?
Its in-hull design removes the transducer for storage and transport, preventing damage and eliminating drag while trailering. Simply drain the tank and store dry.
How does CHIRP technology improve fishfinding?
CHIRP sends a continuous sweep of frequencies, providing better target separation, sharper images, and fewer arcs than traditional fixed-frequency sonar.
Can it handle high-speed operation?
Yes, when properly installed with the correct fluid and hull location, it performs reliably up to planing speeds, though optimal for 10-25 knots.
What's the best hull material for this transducer?
Fiberglass works best due to acoustic transparency. Avoid cored hulls or those with heavy barriers that could attenuate signals.
Does deadrise angle affect performance?
The kit allows precise matching up to 30°, ensuring the beam projects straight down for undistorted readings across various hull shapes.
What fluid should I use in the tank?
Use a marine-grade, non-freezing propylene glycol mix or dedicated sonar coupler fluid to match sound velocity and prevent freezing in cold climates.
Is it compatible with all Raymarine sounders?
It pairs perfectly with Axiom, Axiom Pro, and Element series that support 1kW CHIRP transducers for full dual-channel operation.
The M265 is an outstanding in-hull option with 8 internal ceramics and up to 117 Kilohertz of total CHIRP range. The in-hull installation eliminates the need to drill any holes in the hull, while accommodating a large range of dead rise angles. The high frequency provides excellent shallow water resolution. The transducer is installed in the included tank which is cut to the boat’s dead rise angle and affixed inside the hull. When the transducer is placed inside the tank, it is properly oriented for optimal performance. The M265 is a popular choice for customers not wanting to drill a hole in their hull and for trailered or lifted boats.
