LS-Series & EFI Inboard Engine Swaps
Bergen Performance Marine builds complete inboard engine-conversion projects around modern LS-series power, electronic fuel injection, marine cooling, exhaust, fuel delivery, wiring, controls and driveline compatibility.
A Complete Conversion — Not Just an Engine Drop-In
An LS or EFI conversion changes more than the long block. The engine, mounts, bellhousing or transmission interface, raw-water and closed-cooling systems, exhaust, fuel system, wiring, ECM, controls and instrumentation all have to work together in a marine environment.
LS-Series Engine Packages
Evaluate LS-based engine options around the vessel, desired power level, engine-bay dimensions, drive or transmission and intended use.
EFI Conversion
Convert compatible carbureted or older fuel-injected marine applications to modern electronic fuel injection where the project and engine platform support it.
ECM & Harness Integration
Engine-management wiring, sensors, ignition, relay and power distribution, start/run circuits and diagnostic access are planned as one system.
Fuel-System Upgrades
Evaluate tank pickup, filtration, feed and return requirements, pressure regulation, pumps, hose compatibility and engine-demand requirements.
Marine Cooling & Exhaust
Raw-water supply, closed-cooling components, heat exchangers, manifolds, risers, exhaust routing and engine-bay ventilation are reviewed for the application.
Driveline & Mounting
Engine mounts, alignment, bellhousing or transmission interface, couplers, shaft or sterndrive compatibility and available engine-room clearance are evaluated before installation.
Holley EFI Integration
As a Holley EFI dealer, Bergen Performance Marine can incorporate applicable Holley EFI components into selected marine conversion projects, including engine management, harnessing, fuel-system components, sensors and related controls where appropriate for the engine and installation.
Common Reasons Owners Consider an LS / EFI Swap
Older engines and engine-management components can become increasingly difficult to support.
Owners may want more consistent starting, fueling and drivability than an aging carbureted setup provides.
A conversion can support a broader engine and controls strategy when the hull, drive and supporting systems are appropriate.
When the existing engine is no longer worth rebuilding, a properly engineered replacement can modernize the entire package.
What We Evaluate Before Quoting a Swap
Existing engine and horsepower
Sterndrive or transmission model
Engine-bay dimensions and access
Engine mounts and stringer condition
Fuel-system layout
Cooling-water supply
Exhaust routing
Electrical and charging system
Controls and instrumentation
Weight and balance considerations
Our LS / EFI Conversion Process
Document the existing engine, driveline, mounts, wiring, fuel, cooling and exhaust system.
Define the engine, EFI strategy, mounting, driveline interface and supporting systems required.
Remove the existing powerplant as approved, complete fabrication or rigging work and install the new package.
Complete wiring checks, EFI setup, system diagnostics, operational testing and final commissioning.
Marine Compatibility Matters
Automotive LS components are not automatically suitable for marine use. Final component selection must account for ignition protection, fuel-system requirements, cooling, corrosion exposure, exhaust, ventilation, driveline loading and the boat's existing certification and installation constraints.
Project scope and available engine/EFI combinations vary by vessel. Final recommendations are made after inspection and compatibility review.
