Key West · Florida Keys Built in Milford

Championship
power for
Key West.

Sterling has been winning on this water for three decades. We build in Milford, Michigan, dyno-verify every engine before it leaves, then crate and ship it to wherever you race — including the Keys.

The week that
decides it.

Key West closes the offshore season. The APBA World Championship runs November 1–8, and the 34th annual Key West Powerboat Week overlaps it November 4–9 with more than 200 poker run entries — the climactic event on the circuit.

Built for it

Class-mapped power.

Before a part is cut we map the power band to your class, your hull and the conditions you'll actually race. Super Cat spec, Class 1, or an unlimited program.

Proven here

A thirty-year record.

UIM Class 1 world titles, APBA and SBI offshore championships, four straight APBA National Super Cat titles. Won on open water, not on a spec sheet.

Delivered

Crated and shipped.

Michigan to the Keys is a solved problem. Engines leave Milford broken in and dyno-verified, crated for freight, with the sheet in the box — and we cover the first $500 of it.

Offshore pedigree

We've been
here before.

Three UIM Class 1 World Championships in the nineties. APBA, SBI and OSS offshore titles through the 2000s. SBI Super Cat world and national titles across the 2010s. Four consecutive APBA National Super Cat championships with M CON from 2021 to 2024.

We supply power for record-setting boats from Skater, MTI, Fountain Performance, Donzi, Cigarette, Outer Limits, Sonic and Nortech — the same names you'll see on the dock at Key West.

Choosing a builder

Easy isn't
better.

We understand the pull of the shop down the road. It's convenient, you can drive over on a Saturday, and it feels like less risk. But convenience and capability are not the same thing. The question isn't who sits closest to your slip. It's who has built the engine that wins your class.

Sterling has powered championship boats across the country and overseas for nearly four decades, from APBA offshore circuits to Class 1 Grand Prix racing in Dubai. A phone call, a freight crate and a verified dyno sheet close most of the distance.

Let us be your local guy.

Milford to
the Keys.

You don't need to be in Michigan to run Sterling power. Here's how a build works when you're fourteen hundred miles away.

STEP 01
The conversation

Your class, your hull, your goals and your budget. We quote and schedule every build individually.

STEP 02
Hand assembly

Built on the bench in Milford, every clearance measured, with a fully custom calibration.

STEP 03
Broken in, verified

Run on the dyno and verified by hand before it ships. The sheet travels with the engine.

STEP 04
Crated and supported

Freighted to your shop or your team, with expert support from track to water.

Free Shipping

We cover the first $500 of freight.

Distance shouldn't decide who builds your engine. On crated engine shipments, Sterling pays the first $500 of the freight bill. You only cover anything beyond it.

Frequently Asked Questions

No — and we'd rather say so plainly. Sterling builds in one place: our shop at 54420 Pontiac Trail in Milford, Michigan. That's deliberate. Every engine is assembled, calibrated and dyno-verified by the same people, then crated and shipped to you. Sterling power has won everywhere from APBA offshore circuits to Class 1 Grand Prix racing in Dubai, none of it from a local storefront.

Yes. We crate and ship completed engines, and we work with racers, builders and owners well beyond Michigan. Sterling covers the first $500 of freight on crated engine shipments — you only pay anything above that. Get in touch and we'll sort out the logistics along with the build.

Our record spans UIM Class 1, APBA and SBI offshore, Super Cat including 750 HP spec, and unlimited superboat classes. Engines are built naturally aspirated, supercharged or turbocharged, with the power band mapped to your class rules and your hull.

Every build is quoted and scheduled individually — timing depends on scope, spec and parts availability, and we'll give you a realistic timeline up front. If you're building toward a November world championship, start the conversation early in the season rather than late.

Yes. You don't have to be a racer to expect the best. We build high-end marine power for cruisers and pleasure boats with the same race-level precision, customized for how you run the boat — poker runs included.

Absolutely — and we don't just refurbish, we transform. Our rebuilds are championship-grade refits: every internal hand-checked, every clearance measured, brought back to spec and back to peak dyno numbers, including full machine work. See what goes into a rebuild.
