Remanufactured vs. Rebuilt - What You Need to Know

We get lots of questions about our engines here at Marine Parts Warehouse—and we welcome them! As outboard motor specialists, we are happy to address customer questions and make our customers comfortable with their purchase.

Far and away, though, the question we are most often asked is:


And we understand—outboard parts are a big purchase, and folks want to know how we accomplish a clean, trustworthy remanufactured product. We want every customer to feel confident purchasing from us, so here’s a quick explanation of our remanufacturing process, from our initial core purchase to shipping a like-new remanufactured part out to you.

The first thing we want our customers to know is that we offer products that are remanufactured, not just rebuilt. This means our products are manufactured into new products and all the internal parts are replaced.


remanufacutured-image-8.jpgTake a 1995-1998 3 Cylinder 50-70 HP Johnson & Evinrude Powerhead (SKU # OM-P3- 99-R).  The Powerhead would have the following NEW parts installed after the machine work has been done:

  • New pistons,
  • Rings,
  • Clips and pin
  • Complete gasket and seal kit
  • New rod bearings
  • New wrist pin bearings
  • New crank bearings
  • New rod bolts


And a remanufactured gearcase would receive the following NEW parts:

  • New gears
  • New seal kit
  • New bearings
  • New clutch dog
  • New pinion nut
  • New clutch dog spring and pin



1.  Core Purchasing/Inspection

Our first step is a thorough inspection of every powerhead or gearcase we purchase. Our experts carefully consider each part from every angle to ensure the part can be remanufactured like new. This means that some parts simply do not meet our strict standards for resale. We only buy quality parts so we can pass quality on to you.

2. Cleaning

Next comes cleaning. The parts that meet our initial standards requirements are fully disassembled and each piece is cleaned in a high-pressure jet acid bath then carefully re- examined.

3. Machine Work

An engine only runs if the machine work is done correctly and this is by far the most important step in our process. Our experts have spent years learning how to carefully re-machine any wear and tear so that every piece of the engine runs like new. State of the art Rottler and Sunnen Hone and Bore Machines ensure proper machine work and performance down the road. All cylinders will be bored to the same size and no more than .030 over to allow future machine work if needed. We want our customers to have long-term use out of the products we sell.

4. Reassembly


At this point, it’s time to put the pieces back together. Because of proper cleaning and machine work on powerheads, our reassembly and calibration process goes quickly and smoothly. We assembly 10-50 gearcases or powerheads at a time, and we only use new parts in our products.

5. Painting


We know our customers care about their boats, and they want a product that looks as great as it runs. We take great care to ensure that every part looks clean and has a professional paint job.

6. Inventory

After the painting process, our products are foam-packed, boxed, and placed in inventory. We have a daily inventory update letting us know how many of each SKU we have on hand at any time. This allows us to get the product to you quickly and efficiently.

7. Shipping

We’ve shipped thousands of parts around the world, so we know what it takes to ensure each one arrives safely internationally and domestically. And that’s it.
