Rebuilt vs. Remanufactured Outboard Parts: What’s the difference?
Rebuilt and remanufactured outboard motor parts often get confused. From the outside, the two seem to be very similar products, so what exactly is the difference? Despite their visible parallels, you'll discover that when comparing rebuilt vs. remanufactured outboard parts, there are quite a few differences.
Check eBay or Facebook, and you can likely find a rebuilt version of any outboard part you can think of. But what does a rebuilt unit provide? The obstacle a lot of people run into is verifying the quality of a rebuilt part. Depending on who is performing the rebuilding, standards can vary. The rebuilding process for an outboard motor typically prioritizes replacing damaged parts. Now, that doesn’t necessarily mean that those are the only parts that will be replaced, but it does give you an idea of what a bare-minimum rebuild job might entail. That said, there are plenty of rebuilders who go above and beyond to provide the best possible quality to their customers. As with any industry, there is variety when it comes to expectations and quality, but without a widely accepted standard for the exact definition of a rebuild, finding a trustworthy source can sometimes be challenging.
Remanufactured outboard motor parts can provide the same affordability as a rebuild, and they both begin with “Re- “, but the similarities end there. Reman units are built to adhere to original equipment (OE) specifications. At OBR, almost every component that goes into a reman unit is new and sourced from the same suppliers used by OE manufacturers. Read more about the process here.
While remanufacturing is a more consistent process, there will be slight differences from company to company. Below is a table comparing the general rebuilding process to OBR’s remanufacturing process.
| Rebuilt | OBR Reman | |
|---|---|---|
| Starting point | Used core | Used core |
| Disassembly | Can vary, many times unit is only checked | Complete disassembly |
| Cleaning | Varies by rebuilder | Fully cleaned, blasted, polished, repainted |
| Inspection | Focus on failed components | Systemic inspection of ALL components |
| Parts Replaced | As needed | Defined remanufacturing standards: gears, bearings, seals, O-rings, gaskets, thermostats, pistons |
| Process consistency | Depends on rebuilder | Defined, repeatable remanufacturing process |
| Testing/Warranty | Often none or 30 days | Quality-control process, 2-year warranty |
The Right Decision for You
So, what difference does it make? As boat owners, we know the importance of making informed decisions that are reliable long term. At OBR, our standardized remanufacturing process ensures you’ll always get the same high-quality product, without having to gamble on if this year’s rebuild unit will hold up as well as they have in the past. Customers can truly rely on our product knowing that each component has been inspected, not just the failed ones. Ultimately, the peace of mind that comes with knowing the unit going on your boat – where it came from, how it’s made, and the standards it’s held to – is rarely worth compromising. At OBR, we stand firmly behind our quality standards, so much so that we offer a 2-year warranty as opposed to the industry standard of one.
If you ever find yourself struggling to decide whether an aftermarket unit is up to your standards, whether that be rebuilt or reman, don’t hesitate to ask the important questions. We’ve put together a list of some that will help you make the most informed decision.
- Was the unit completely disassembled?
- Which components were replaced? Reused?
- How were the reused components inspected?
- Who manufactures the replacement components that were used?
- Does the unit come with a warranty?
- Did the seller perform the rebuild/remanufacturing themselves?
The Honest Answer
So, are remanufactured and rebuilt the same? No. While both rebuilt and remanufactured outboard components begin with used units, the terms represent vastly different processes. A rebuild generally focuses on restoring the unit to working condition, while remanufacturing involves a more comprehensive, standardized process including disassembly, inspection, component replacement, and reassembly.
Each distributor, company, or mechanic can have different standards and expectations, so be sure to do your homework before buying the first part you see on eBay. But all in all, purchasing from sellers with a long-standing, substantiated process, like OBR, is the best way to ensure you’re getting the product quality you can count on.
