Core Marine Diesel Services (Ventura • Santa Barbara • Channel Islands)

1) Engine Diagnostics & Corrective Repair

Your engine is the heart of your boat—any inconsistency deserves fast, accurate diagnosis. We combine mechanical testing with electronic data to pinpoint root causes, not symptoms. Common service items include injector and pump performance checks, boost and compression assessment, crankcase pressure trends, and hot/cold start behavior. Our process eliminates guesswork and restores rated power while preventing repeat faults.

2) Scheduled Maintenance (100/300-Hour & Annual)

Periodic service is the lowest-cost way to keep hours productive and predictable. We document every interval (oil and coolant analysis available) and align tasks to manufacturer schedules and your duty cycle. Typical scope includes fluid and filter changes, tensioning/renewal of belts, valve lash checks where applicable, zincs, anode inspection, mounts and alignment checks, and comprehensive leak/fastener surveys.

Periodic maintenance service such as 100 Hrs., 300 Hrs., etc.), inspection, oil/chemicals change, and the replacement of consumable parts.

are fundamentals for all the boaters to have a trouble-free cruising experience on the water for many years to come.

3) Cooling, Fuel & Seawater Systems

Most “mystery performance losses” trace back to heat exchange or fuel quality. We clean/descale coolers, renew impellers, pressure-test heat exchangers, verify thermostats, and ensure raw-water flow meets spec. On the fuel side, we service primaries/secondaries, polish fuel (as needed), and test lift/rail pressure to protect injectors and pumps. This holistic approach keeps EGTs, oil temps, and load within design targets.

4) Marine Transmission & Driveline

Shifts should be crisp, quiet, and predictable. Our transmission service covers fluid and filter changes, pressure checks, shift cable/linkage set-up, dripless seals, cutlass bearings, and alignment to protect gears and reduce vibration. We also evaluate couplings and mounts and can recommend upgrades where appropriate.

5) Generator & Electrical (Diesel)

Reliable hotel loads start with a healthy diesel genset and clean power distribution. We service diesel marine generators, perform load testing, inspect wiring, charging and starting circuits, and correct corrosion at terminals and grounds. Preventive attention here avoids nuisance shutdowns and protects electronics.

6) Engine Rebuilds & Repower Planning

When it’s time to restore performance or upgrade, our rebuild and repower program returns efficiency, reduces emissions, and improves NVH (noise, vibration, and harshness). We handle removal, component cleaning/measurement, machining coordination, and precision reassembly with documented torque/angle procedures. If a repower is right for you, we guide engine selection, horsepower and prop matching, shaft/strut/cutlass considerations, cooling and exhaust capacity, fuel return and filtration, and control integration.

Brands & Platforms We Service

We support a wide range of inboard diesel platforms—matching OEM procedures and torque values to preserve longevity and compliance. That includes Cummins Marine, Volvo Penta Marine, Yanmar Marine, Caterpillar Marine, Beta Marine, Scania Marine, FPT Marine, MTU Marine, Ford Lehman, Perkins Marine, and more. If your yacht carries twins or a single main with a genset, we can help you configure a maintenance plan that fits your hours and mission.

Proactive Care that Prevents Costly Failures

Unplanned failures almost always cost more than planned service. We emphasize:

• Fuel system diligence: Primary/secondary filtration, water separation, line integrity, and periodic tank checks.
• Cooling assurance: Raw-water pump health, impellers, heat-exchanger descaling, and coolant chemistry management.
• Exhaust health: Mixing elbows and risers are routine inspection items; rust and restriction cause backpressure and heat. See our Marine Diesel Engine Maintenance Schedule for guidance.
• Fasteners & mounts: Securing hardware and alignment checks reduce vibration, extend seal life, and protect gears.

Mobile Marine Service Across the 805

Dockside or in the yard, our mobile units bring dealership-level capability to you—compression and leak-down tooling, fuel pressure/vacuum instrumentation, cooling system test gear, and electrical load/charging analyzers. This saves tow cost and calendar time, and it means we see the installation exactly as it’s operated.

Service Areas

We proudly support owners at Ventura Harbor, Channel Islands Harbor, Santa Barbara Harbor, and surrounding marinas. Whether you run day trips to Anacapa or extended Channel Islands cruises, we align maintenance with your patterns to limit interruptions during peak weather windows.

Our Proven Process

1. Listen & baseline: We capture symptoms, hours, alarms, and recent work. Then we baseline with visual checks and measurements.
2. Test & verify: We run targeted tests (fuel, air, cooling, electrical) to isolate the cause.
3. Plan & quote: You receive a clear, prioritized plan—safety-critical items first, efficiency next, cosmetics last.
4. Execute & document: Work is performed to OEM spec and documented with findings and recommendations.
5. Follow-up: We schedule the next interval and provide tips to monitor between visits.

When a Repower Makes Sense

If your current plant struggles to make RPM, smokes under load, or fails emissions/efficiency expectations—even after correction and maintenance—a repower can be the most economical path. Benefits include reduced emissions, better fuel economy, increased cruise speed, lower noise/vibration, and improved reliability. We’ll help with horsepower sizing, weight and footprint checks, shafting and prop pitch, air/exhaust capacity, and fuel return requirements so the new engine works as a system—not just a swap.

Owner Education & Preventive Tips

• Spot-check for weeping at hose ends, the raw-water pump, and cooler caps—early drips are cheap wins.
• Monitor temperature and oil pressure trends; any deviation under the same load deserves attention.
• Keep spares: belts, impellers, filters, and a clean fuel source for priming.
• Inspect the mixing elbow each season for scale and rust; clean or replace if restricted.
• Log hours religiously; tie service to hours, not just calendar months.
