What are common symptoms of a marine engine needing repair?

Hard starting, loss of power, strange noises, overheating, or smoke from the exhaust all point to engine issues. We run full diagnostics to locate the exact cause and restore peak performance.

Do you work on both gas and diesel marine engines?

Yes – we specialize in both gasoline and diesel engines, including inboards, outboards, and sterndrives. We service top brands like Cummins, MerCruiser, Volvo Penta, and Yanmar.

How much does marine engine repair typically cost?

Minor repairs start around $250. Full diagnostics and major repairs can range from $500 to $3,000 depending on the engine type and issue. We always provide a quote before work begins.

Can you fix engine overheating or cooling system problems?

Absolutely. Overheating is often caused by clogged raw water intakes, failed water pumps, or bad thermostats. We inspect your entire cooling loop and fix the root cause to protect your engine.

Do you offer mobile marine engine repair at the dock?

Yes – we provide mobile engine repair services across Orange and Los Angeles County. Whether you're docked or on a trailer, we’ll come to you with tools and parts to get your engine running right.

Can you restore a boat engine that’s been sitting for years?

Yes – we specialize in bringing dead engines back to life. From fluid flushes to carburetor rebuilds and compression testing, we evaluate what’s salvageable and replace what’s not.

Do you repair fuel injection systems and ignition timing on marine engines?

Definitely. We handle EFI, MPI, and carbureted engines. We tune ignition timing, clean injectors, and calibrate fuel maps to improve performance and fuel economy.

What is a powerhead swap and why is it needed?

A powerhead swap involves replacing the engine’s top end with a remanufactured unit. This restores performance, improves fuel efficiency, and solves issues like low compression or poor running.

How long does a powerhead replacement take?

Typically, the process takes 1–2 days depending on engine size and complexity. We ensure proper installation, alignment, and full testing for reliable operation.

Are remanufactured powerheads as reliable as new ones?

Yes, remanufactured powerheads are rebuilt to OEM specifications, tested for performance, and often come with a warranty, providing reliable and cost-effective engine performance.

Can a powerhead swap improve fuel efficiency?

Absolutely. A properly installed remanufactured powerhead restores optimal combustion, reduces fuel consumption, and ensures smoother engine operation.

Do you also install gaskets and seals during a powerhead swap?

Yes, we replace all necessary gaskets, seals, and components to prevent leaks, maintain proper compression, and ensure the engine operates efficiently.

Can you service both inboard and outboard engines with a powerhead swap?

Yes, we handle both inboard and outboard engines, tailoring the swap process to the specific engine type to ensure maximum performance and longevity.

Is post-installation testing included with a powerhead swap?

Yes, after installation we perform full engine testing, including compression, idle, and load tests, to verify performance and ensure your engine runs smoothly on the water.

What is ultrasonic cleaning for heat exchangers and aftercoolers?

Ultrasonic cleaning uses high-frequency sound waves in a cleaning solution to remove scale, salt, and corrosion from internal passages, restoring efficient heat transfer and engine cooling.

How often should I clean my heat exchanger or aftercooler?

For optimal performance, we recommend cleaning at least once a year, or more frequently if the engine operates in saltwater or silty conditions.

Does ultrasonic cleaning damage engine components?

No, ultrasonic cleaning is gentle on materials. It reaches internal passages that manual cleaning can’t, effectively removing buildup without harming metal surfaces.

Can ultrasonic cleaning improve engine efficiency?

Yes, removing scale and deposits restores proper coolant flow and heat exchange, reducing engine operating temperatures and improving overall performance.

Is this service suitable for both inboard and outboard engines?

Absolutely. We service both inboard and outboard engines, including marine generators, ensuring efficient cooling and preventing overheating issues.

How long does ultrasonic cleaning take?

The process usually takes a few hours per component, depending on size and level of buildup. After cleaning, we reassemble and test the system for proper operation.
