New OEM Lower Units at US Boatworks
New OEM lower units are built by your engine’s manufacturer — Mercury, Mercruiser, Evinrude, Volvo Penta, or OMC — to exact factory specifications using original components. If you want factory-built quality with no questions asked, this is your option.
Before you order, call us. Most boaters who come to this page thinking they need OEM end up with a remanufactured unit instead — same OEM internal parts, built by our factory-trained technicians in Kansas City, at a fraction of the cost. We’ll tell you straight which option makes sense for your situation.
- Built by your engine’s manufacturer to exact factory specs
- All parts are OEM — guaranteed compatibility
- Usually ships in 24 hours — we stock popular units
- Optional rebate when you return your old core
- 1-year warranty covered by the manufacturer
Filing an insurance claim? Insurance occasionally covers OEM but most insurers approve remanufactured as the standard replacement. Call us before you file anything — our owner works directly with adjusters and in most cases gets reman approved, which puts money back in your pocket.

Do You Actually Need OEM?
Most boaters assume OEM is the only reliable replacement option. That’s what boat shops tell them — because ordering direct from Mercury or Volvo Penta is the path of least resistance for a shop. It doesn’t mean it’s the right path for you.
Here’s the truth after 40 years in this business: a remanufactured lower unit built with genuine OEM internal parts performs the same as a new OEM unit on the water. The difference is price — often $500 to $1,500 less for the same result.
We’re not telling you OEM is wrong. Sometimes it’s exactly the right call — particularly when you want factory-built peace of mind or your situation specifically requires it. We stock the most popular OEM units so you don’t have to wait weeks for a dealer to order one.
What we are telling you is this: call us before you decide. We’ll give you the honest comparison for your specific engine and situation. 85% of customers who call us asking about OEM end up choosing remanufactured — not because we pushed them, but because once they understood the difference, the choice was obvious.

Most Asked Questions
What makes OEM lower units a reliable choice for marine propulsion?
OEM lower units are built by your engine’s manufacturer — Mercury, Mercruiser, Evinrude, Volvo Penta, or OMC — using original factory components to exact specifications. Compatibility is guaranteed and there’s no guesswork involved. For boaters who want factory-built quality and are paying out of pocket, OEM is a legitimate choice.
Can I file an insurance claim for the damage to my lower unit?
Yes — and you should call us first. Insurance occasionally covers OEM but most insurers approve remanufactured as the standard replacement. Our owner handles every claim personally and works directly with your adjuster. In most cases we get remanufactured approved, which costs you less out of pocket and gets you back on the water just as fast.
Why is choosing an OEM lower unit considered a long-term investment?
OEM is the factory-built option — built to exact manufacturer specs with original components. For boaters who want done right once without compromise, it’s a solid choice. That said, a remanufactured unit built with genuine OEM internal parts performs the same on the water at significantly lower cost. Call us and we’ll help you decide which makes more sense for your situation.
What is the key advantage of choosing a new lower unit?
You get exactly what your engine’s manufacturer intended — original components, factory assembly, guaranteed compatibility. No variables. If that peace of mind is worth the price premium to you, OEM is the right call. We stock popular units so you don’t have to wait weeks for a dealer to order one.
What brands of OEM lower units are available at US Boatworks?
We carry new OEM lower units for Mercury, Mercruiser, Evinrude, Volvo Penta, and OMC. We stock the most popular units — call us to check availability before you order. Have your serial number or model number ready.
What warranty and rebate options come with new lower units from US Boatworks?
New OEM lower units come with a 1-year warranty covered directly by the manufacturer. An optional core return rebate is available when you send back your old unit — rebate amount depends on the condition of your core.
