Most Asked Questions
What is a remanufactured lower unit?
It’s your lower gearcase completely disassembled, inspected, and rebuilt using OEM parts — not cheap aftermarket components. You will only find OEM parts in our lower units. Not all rebuilders use quality OEM parts.
The result is near-new performance at a fraction of new OEM cost. Every unit we sell is tested before it ships.
What brands do you offer remanufactured lower units for?
Mercury, Evinrude-Johnson, Force, Mercruiser, Volvo-Penta, and OMC. Have your engine model number or serial number ready and we’ll confirm the right fit before you order.
How do I know the quality is consistent?
Because we control the process start to finish. Every unit is built in our Kansas City shop by factory-trained career technicians using OEM parts. We’ve been doing this for 40+ years — our reputation depends on getting it right every time.
Is the quality consistent across all remanufactured units in the market?
Quality may vary among rebuilders, depending on their remanufacturing procedures. It’s crucial to purchase from a trustworthy source like US Boatworks, ensuring reliability and quality parts. Read reviews on other rebuilders to verify quality and reliability.
Is a remanufactured unit as good as new OEM?
For most boaters, yes. Same OEM internals, same performance, backed by our 1-year warranty. The difference is price — you save hundreds compared to new OEM. If you want the absolute best available, we carry new OEM units too. Check out our menu items up top for OEM Lower Unit choices.
Will my insurance cover a remanufactured lower unit?
Often yes — and most boaters don’t think to ask. Call us for assistance. Our owner handles insurance claims personally and works directly with your adjuster to get you the best outcome.
Can I install this myself?
Many of our customers are do-it-yourselfers and if your comfortable with install, by all means, do so. If you prefer not to install yourself, we can ship your unit directly to your boat shop so they can complete the install. We ship thousands of sterndrives directly to boat shops each year.
How fast will my order ship?
We try our best to ship your unit out in 24 hours, most times we ship them out the same day it was ordered. Some units may need to be built in house. If this is the case, we call you with an estimated shipping date. We prioritize getting these units out as quickly as possible. We will also send you a tracking number the moment it leaves our warehouse.
