Finding the Right Parts Without Losing Your Mind
The Lowrance Ghost Trolling Motor Parts Diagram is one of those things that looks straightforward until you're standing on a boat deck at 6 AM trying to figure out which plastic shroud covers which bolt, and the manual has gone somewhere. I've been working with these motors for years and still keep a printed copy of the diagram taped to my toolbox. The PDF is available through Lowrance's support site, but honestly, the printed version saved me more than once when the dockside lighting was terrible. Here is what you need to know about the diagram itself, where to find it, and the parts that actually tend to fail on the Ghost series.
Lowrance Ghost Trolling Motor Parts Diagram
Lowrance publishes the official parts breakdown through their website under the Ghost product page. You go to lowrance.com, navigate to Support, then Product Support, search "Ghost," and you will see a link labeled Parts Diagram or Exploded View. The file is usually a PDF showing the motor shaft assembly, the control head housing, the transducer mounting hardware, the propeller and thrust ring, the battery connection block, and the remote control components. Each part gets a reference number that matches a bill of materials. The reference numbers matter because Lowrance does not sell most components as standalone retail items. You order by part number. If you guess based on a photo, you will end up with something that looks right but has the wrong thread pitch or mounting hole spacing. I learned that the hard way. A few years ago I replaced a propeller on my Ghost 10 and grabbed the wrong thrust ring from a parts sheet I had downloaded from a third-party fishing forum. It bolted on fine visually, but the thrust ring was machined for a Ghost 8, and the propeller sat about three millimeters too high on the shaft. It caused a vibration that sounded like a loose bearing. Took me twenty minutes to realize the issue once I held the two rings side by side against the diagram. The solution was simple — order part number 000-14568-001 directly from Lowrance or an authorized dealer and swap it out. That took about ten minutes with a standard socket set.
What the Diagram Actually Shows
For the shaft-mount Ghost, the main assemblies are the motor housing, the shaft collar, the universal joint pivot, the propeller nut, the thrust bearing assembly, and the remote bracket hardware. The bow-mount version adds a head unit with built-in electronics mounting points and a different steering linkage. The control head diagram breaks down into the display module, the power switch assembly, the memory jog dial, and the fuse holder. Those are the parts people buy replacements for most often because the jog dial wears out from use and the fuses blow when someone connects the battery backwards, which happens more than you would think. On the transducer side, the Ghost ships with a built-in transducer in most configurations, so you are not dealing with a separate cable assembly. The wiring diagram shows a thick red power lead, a black ground lead, a blue remote cable, and a yellow sensor wire. If you are running a wireless remote like the iDevices Remote, the yellow wire connects to the SonarHub. Getting that connection wrong causes the depth finder to read noise instead of bottom structure, and it looks like a bad transducer until you check the wire seating.

Common Failure Points and What to Replace
The propeller is the easiest thing to replace. It wears down from hitting debris, and the nylon insert on the prop nut can strip if you overtighten it during installation. The recommended torque is around 15 to 18 foot-pounds. Anything over 20 foot-pounds risks cracking the plastic housing on the lower unit, and that is not a cheap part to replace. The thrust bearing tends to develop play after 500 to 800 hours of heavy use, especially if you are trolling in rocky shallows and the motor bumps the bottom regularly. When you feel side-to-side movement in the shaft while the motor is running at idle speed, that is usually the bearing. Replacing it requires removing the lower cowling, which takes about 20 minutes with a basic tool kit. The universal joint pivot bushing is another item that wears. It is small, it is easy to lose, and it is also the part that makes the motor feel sloppy when you are trying to hold a precise position on Lake Mitchell during a calm morning. Lowrance sells it as part of a maintenance kit sometimes, but not always. Check the diagram and look for the bushing reference number before you order.
Ordering Parts: What to Watch For
Lowrance updates part numbers occasionally when they improve a component. If you order a part using a diagram from a motor manufactured in 2021 and your motor is from 2023, some numbers may have changed. Always verify the serial number on your motor against the diagram version on Lowrance's site. The serial number is on a sticker near the control head or on the shaft collar, depending on the model. Third-party sellers sometimes list compatible parts that are close but not identical. I have seen people buy generic propellers that fit physically but throw off the balance. A slightly unbalanced prop on a 10-pound thrust Ghost will cause noticeable vibration at higher RPM settings, which defeats the whole point of having a quiet trolling motor in the first place. Lowrance also sells a maintenance kit for the Ghost that includes the thrust bearing, the pivot bushing, a new prop nut washer, and a silicone grease packet. It costs around sixty dollars and saves you from ordering individual parts separately. If you are doing annual maintenance, it is worth the price.
Wiring Issues That the Diagram Will Not Help With
The parts diagram covers hardware. It does not cover every electrical failure you might encounter. If your Ghost stops responding to the remote but the motor still runs on the handlebar throttle, the problem is usually in the remote receiver module or the wiring harness between the control head and the motor. Check the fuse first. Then check the blue remote cable connections at both ends. They use a quick-disconnect connector that can corrode if water gets into it, which it will if you are launching and retrieving the motor frequently. I once spent an hour troubleshooting a Ghost that would not engage at all, only to find that the quick-disconnect on the blue wire had green corrosion inside the housing. Cleaning it with contact cleaner fixed it immediately. The parts diagram did not show that connector, which is why having a wiring schematic alongside the parts diagram is useful. Lowrance includes both in the same support document package.
When to Use an Authorized Dealer Instead of Ordering Online
Some components, especially the control head PCB and the display module, are not always available as direct-to-consumer parts. Lowrance sometimes restricts those to authorized service centers. If you are ordering from the website and a part says "call for availability," it is probably one of those restricted components. In that case, taking the motor to a licensed dealer or having them order it for you is faster than waiting on backorder, which can stretch to six to eight weeks depending on demand. The Ghost is a solid motor, but like anything mechanical, it needs periodic attention. The parts diagram is your reference point, but the real value comes from knowing which parts wear, which ones you can replace yourself, and which ones require professional service. Keep the diagram accessible, order by reference number, and do not skimp on the maintenance kit when you are due for annual service.
