Raymarine R71017 RCU-1 Wireless Autopilot Remote Battery Door

If you own a Raymarine RCU-1 Wireless Autopilot Remote and the battery door has cracked, warped, or gone missing, this is the part you want. The R71017 is the genuine Raymarine replacement door, molded in the same black plastic as the original. It's a small piece, but on a wireless remote that lives in the cockpit and takes a beating, it's the difference between a remote that seals up tight and one that lets moisture creep in.

Here's the thing about battery doors on handheld marine gear. They take the most abuse of any part on the unit. You're opening them to swap AA cells, they get dropped, they sit in the sun, and the little clips that hold them shut fatigue over time. We've seen plenty of remotes come through where the electronics are perfect but the door won't latch anymore. Rather than replace the whole RCU-1, you swap the door and you're back in business for a fraction of the cost.

The RCU-1 itself runs on two standard AA batteries and pairs to your Evolution autopilot through the WG-1 wireless gateway. That means the remote is your handheld link to the pilot, whether you're up on the foredeck setting an anchor, trimming sail solo, or just want to nudge your heading a few degrees without walking back to the helm. So keeping it sealed and reliable matters. A loose or missing door lets spray and humidity reach the battery contacts, and corroded contacts are the fastest way to kill a remote that's otherwise fine.

Installation takes about a minute and needs no tools. Line the door up with the channel on the back of the remote, seat it evenly, and let the clips engage. Don't force it at an angle. Those clips are the one spot people crack, usually by trying to snap one corner down before the other side is seated. Get both sides aligned first, then press it home. Once it clicks, give the remote a gentle shake to confirm the door's locked and the batteries aren't shifting.

One quick check before you order. Make sure your remote is actually the RCU-1 and not an older Raymarine handheld like the S100. The R71017 door is cut for the RCU-1 housing specifically, so it won't fit the older units. The model is usually printed inside the battery compartment or on the box, and if you're not sure, send us what you've got and we'll confirm the right part.

Because it's the real Raymarine part and not a generic knockoff, the fit is exact. The door matches the original tolerances, so it sits flush and the sealing surface lines up the way it should. If you're going to fix the seal, fix it right. A door that sits proud on one edge or won't hold clip tension defeats the whole point of replacing it.

A couple of practical tips while you've got it open. It's worth wiping the battery contacts and the inside of the door with a dry cloth before you close it up, especially if the old door had been letting water in. If your remote lives outdoors full time, a lot of owners run lithium AA cells to stretch the service interval, which means fewer door openings and less wear on the clips over the life of the remote. And if the black plastic on your old door had faded from UV, that's just cosmetic. The new door starts out matching the remote and weathers the same way over time.

Bottom line, this is a simple, honest repair part. If your RCU-1 is solid but the battery door has given up, the R71017 gets you sealed back up without spending on a whole new remote. We keep the genuine Raymarine part in stock and ship it the same day when you order before 3 PM ET.
