🛠️ Precision Marine Engine Maintenance & Field Repairs

We deliver professional technical maintenance and rapid-response repairs for marine propulsion systems servicing both recreational vessels and light-commercial craft. Our workflow blends diagnostic clarity, OEM-compatible parts, and on-site capability so engines are inspected, tuned, and returned to sea-ready condition quickly and safely.

From scheduled tune-ups and fuel-system cleaning to gearbox inspections and winter preservation, our services are tailored to reduce downtime and extend engine life. Book a dockside visit or arrange collection at our workshop for a thorough check and transparent estimate.

ℹ️ About Us

Our company was formed by marine engineers, certified technicians, and logistics specialists who understand the unique demands of outboard and inboard propulsion systems. We operate from a well-equipped workshop and deploy field teams capable of dockside servicing, trailer pick-up and return, and temporary on-site diagnostics. Our technicians undergo continuous training on the latest EFI, DI, and hybrid propulsion technologies so we can service legacy carbureted systems as well as modern electronic fuel and engine-management platforms.

We emphasize clear communication: every job begins with a structured diagnostic, a documented estimate, and an explanation of priority repairs, optional improvements, and preventive measures. Customers appreciate our transparent parts policy—OEM or approved aftermarket—and our commitment to restoring safe, reliable performance rather than quick fixes. Whether preparing a vessel for the season, performing a pre-charter inspection, or resolving unexpected failure, our focus is on minimizing risk, maximizing uptime, and providing durable results.

Environmental responsibility is also core to our operations: fluids are handled under strict containment, waste parts are recycled when possible, and fuel and oil handling procedures meet regulatory standards. We also provide winterization and long-term lay-up services that protect engines against corrosion and condensation damage during off-season storage.

⭐ Company Advantages

Key strengths that ensure dependable results for engine owners and fleet managers.

Certified Marine Technicians & Continuous Training

Our technical staff are certified in marine engine systems and regularly attend manufacturer workshops and independent training sessions. This investment in skills ensures familiarity with diverse platforms—two-stroke and four-stroke outboards, sterndrive packages, inboard diesels, and modern electronically controlled motors. Each technician follows a checklist-driven diagnostic approach that captures fault codes, verifies sensor operation, and confirms mechanical integrity. Beyond immediate repair, technicians recommend preventive maintenance items prioritized by potential impact on reliability and cost-efficiency. This level of training reduces diagnostic time, avoids misdiagnoses that create repeat visits, and builds trust through effective, durable repairs.

Transparent Diagnostics & Documented Estimates

Every service begins with a structured diagnostic report that itemizes observed faults, test results, and recommended actions with estimated parts and labor. Clients receive clear documentation—visual and written—so repair scopes are understood before work proceeds. We record runtime data, compression readings, and fuel-system status where applicable, and attach photos for transparency. This documentation protects owners from unexpected invoices and provides chronological records helpful for warranty claims, resale valuation, and fleet maintenance planning. Estimates separate mandatory safety work from recommended optimizations so boat owners can select options based on budget and operational plans.

OEM Parts & Approved Replacements

To maintain warranty integrity and peak performance, we primarily use OEM parts or manufacturer-approved equivalents. Our parts sourcing channels are vetted so component traceability is preserved and compatibility is verified. For older platforms where OEM parts are discontinued, we identify high-quality alternatives and document any trade-offs. Stocked consumables—filters, impellers, seals, and fluids—allow us to complete most routine jobs without delay. For critical-drive components or electronic modules we coordinate authorized supply to ensure installations follow recommended procedures and calibration steps.

Dockside & Mobile Service Capability

Our field teams carry diagnostic equipment, lifting gear, and a curated inventory of common replacement parts to execute dockside repairs whenever feasible. This minimizes vessel downtime and eliminates the need for trailering in many scenarios. Mobile service is offered for engine troubleshooting, impeller swaps, ignition checks, and minor fuel-system repairs. Complex repairs that require shop tools are scheduled for workshop intake, but we always attempt a temporary fix to restore safe motoring if immediate full repair is impractical. This mobile-first approach reduces the friction of repair and supports customers operating on tight schedules or remote moorings.

Seasonal Programs & Winterization

We offer complete seasonal care packages—including commissioning, mid-season check-ups, and comprehensive winterization—that protect engines from moisture, corrosion, and fuel degradation. Winter services include fuel system stabilization, fogging, cylinder preservation, and careful fluid exchange where required. For extended lay-up we provide desiccant-based storage solutions and battery maintenance. These seasonal processes are designed to prevent common off-season failures and shorten spring commissioning times, delivering year-round reliability and predictable operating windows for leisure and charter vessels.

Safety-First Protocols & Environmental Care

Safety and environment are embedded in our operations. Technicians follow containment procedures for oils and fuels, use spill kits on-site, and dispose of hazardous materials according to regulation. Service checklists include critical safety items—mounting hardware torque, cooling-water flow, and steering/shift integrity—so repairs restore not just function but safe operation. For commercial operators we provide compliance checks aligned with regional survey requirements and can assist with documentation needed for inspections. Our commitment to best-practice handling minimizes ecological impact while maximizing operator confidence.

🛠 Services

Choose from carefully defined service tiers for one-off repairs, routine maintenance, fleet programs, and diagnostic consultations. Each service includes a documented scope, parts/labor breakdown, and options for preventive add-ons such as propeller balancing or fuel polishing.

Full Engine Diagnostic & ECU Analysis

Comprehensive electronic and mechanical diagnostics for modern engines. We interrogate engine control units, retrieve stored fault codes, validate sensor signals, and perform live-parameter logging. Diagnostics also include compression checks, exhaust analysis, and inspection of ignition and fueling subsystems. The service culminates in a prioritized repair plan and a transparent estimate.

Routine Service & Tune-Up Packages

Scheduled maintenance packages cover oil and filter changes, spark plug replacement, impeller and cooling-system service, fuel-filter replacement, lubrication of steering and linkages, and general checks. Packages are tailored by engine hours, application type, and seasonal needs to maximize reliability and fuel economy.

Propulsion Repairs & Drive System Overhaul

We repair sterndrives, lower units, and outdrive gearcases including seal replacement, bearing service, and propeller shaft alignment. For more extensive issues we offer teardown and rebuild services using OEM kits and precision machining where required.

Fuel System Cleaning & Injector Service

We treat clogged injectors, remove varnish and deposits, replace filters, and where appropriate perform ultrasonic cleaning and calibration. These services restore proper fueling, reduce smoke and rough running, and improve throttle response and efficiency.

Winterization, Commissioning & Storage Prep

Off-season preservation, spring commissioning, and battery storage services reduce failure rates and speed return-to-service. Options include full-system preservation and fuel polishing for long idle periods.

Fleet Maintenance & Scheduled Contracts

Tailored fleet programs for charter operators and small commercial fleets: scheduled maintenance, priority response, inventory planning, and aggregated billing. We work to optimize uptime and lifecycle cost.
