Raymarine Bulkhead Fitting Kit E15017

Enhance Your Autopilot Setup with Precision Mounting

Installing a reliable autopilot drive on your wheel-steered vessel demands hardware that stands up to harsh marine conditions while ensuring a secure, watertight fit. The Bulkhead Fitting Kit steps in as the essential component for mounting the drive unit directly through the bulkhead, delivering rock-solid stability without compromising your boat's integrity. Crafted for seamless integration, this kit transforms a complex retrofit into a straightforward upgrade, letting you focus on smooth sailing rather than endless adjustments.

Boat owners often struggle with loose fittings that lead to vibrations, misalignment, or leaks over time. This kit addresses those pain points head-on, using corrosion-resistant materials designed to endure saltwater exposure, UV rays, and constant motion. Whether you're outfitting a new installation or replacing worn parts on an older system, it provides the confidence that your autopilot will perform flawlessly during long passages.

Perfect Compatibility for Seamless Integration

Tailored specifically for the Raymarine 4000 mk2 Wheel Drive, this fitting kit ensures a plug-and-play experience. It aligns perfectly with the drive's mounting points, eliminating guesswork and reducing installation time. It's also versatile enough to work with a range of wheel-steered boats from 30 to 50 feet, making it a go-to choice for sailboats, power yachts, and offshore cruisers.

• Direct fit for Raymarine 4000 mk2 Wheel Drive units
• Compatible with standard bulkhead thicknesses up to 2 inches
• Works alongside common steering pedestal setups
• Supports retrofits on legacy autopilot systems

Pro tip: Always double-check your bulkhead material—fiberglass, wood, or aluminum all pair well, but reinforce thin sections for optimal load distribution during heavy weather steering.

Step-by-Step Installation Guide for DIY Confidence

Getting your autopilot drive mounted doesn't require a marine yard overhaul. Here's a practical walkthrough to get you on the water faster:

1. Prep the bulkhead: Mark the centerline of your steering shaft and trace the kit's template for precise hole placement. Use a hole saw for clean cuts.
2. Assemble the fittings: Thread the flange and thru-hull components with marine-grade sealant, ensuring even torque to prevent leaks.
3. Mount the drive: Secure the wheel drive to the fittings using the provided bolts. Align the output arm parallel to the wheel shaft for zero binding.
4. Test and seal: Cycle the autopilot through full lock-to-lock travel on land. Apply additional sealant around edges and bed the assembly firmly.
5. Final checks: Monitor for play after a few outings; tighten as needed without over-stressing the threads.

This process typically takes 2-4 hours for experienced installers, saving you from costly professional fees. Common pitfalls like misalignment are avoided with the kit's pre-drilled guides and adjustable spacers.

Why This Kit Outperforms Generic Alternatives

In the world of marine hardware, skimping on fittings can lead to catastrophic failures mid-voyage. This kit shines with its robust stainless steel construction—304-grade for the flanges and 316 for high-stress bolts—offering superior resistance to galvanic corrosion compared to off-the-shelf options. Users report zero slippage even under 40-knot winds and confused seas, where lesser kits fail.

Beyond durability, it minimizes vibration transmission to the helm, preserving your wheel bearings and enhancing overall steering feel. For liveaboard sailors or delivery captains, that translates to reliable performance season after season, with minimal upkeep.

Long-Term Maintenance and Troubleshooting Tips

Keep your setup running like new with simple habits:

• Inspect fittings annually for crevice corrosion; rinse with fresh water after every saltwater outing.
• Lubricate pivot points with waterproof grease to prevent seizing.
• If you notice helm feedback, check for debris in the thru-hull path—clear it immediately.
• For unusual noises, verify bolt torque specs to rule out loosening from wave impacts.

These steps extend the kit's lifespan well beyond five years, often matching your autopilot drive's endurance.
