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 valve adjustment and why is it important for marine engines?

Valve adjustment ensures proper clearance between the valves and camshaft, allowing the engine to breathe correctly. Incorrect valve clearance can cause power loss, rough idle, overheating, and long-term engine damage. Regular adjustment keeps your engine running efficiently and reliably.

What does a compression test tell me about my engine’s condition?

A compression test measures the pressure inside each cylinder to evaluate engine health. Low or uneven compression can indicate worn valves, piston rings, or head gasket issues. This test helps diagnose problems before they turn into costly repairs.

How often should valves be adjusted on a marine engine?

Valve adjustment intervals depend on the engine manufacturer, but most marine engines require inspection every 200–300 operating hours. High-performance or heavily used engines may need more frequent checks to maintain optimal performance.

Can improper valve adjustment cause engine starting problems?

Yes. Valves that are too tight or too loose can affect compression and combustion, leading to hard starting, misfires, and poor throttle response. Proper valve adjustment restores smooth starts and consistent power delivery.

What is included in your valve adjustment and compression testing service?

Our service includes checking valve clearances to manufacturer specifications, performing dry compression testing on all cylinders, and documenting results. We also inspect related components and provide recommendations if abnormal readings are found.

Can a compression test help prevent major engine failure?

Absolutely. Compression testing helps identify internal engine wear early, allowing for corrective action before catastrophic failure occurs. Early diagnosis often saves thousands in rebuild or replacement costs.

Do you provide documentation and recommendations after testing?

Yes, we provide a detailed report with compression readings, valve condition notes, and clear recommendations. This documentation is valuable for maintenance planning, resale value, and warranty or insurance purposes.

What is an exhaust riser and why might it need replacement?

The exhaust riser connects your engine’s exhaust manifold to the exhaust system, directing engine gases out of the boat. Over time, it can corrode or crack due to heat and saltwater exposure, which can lead to leaks, reduced engine performance, or water entering the engine.

How do I know if my exhaust riser or elbow is failing?

Signs include white or brown exhaust smoke, engine overheating, unusual noises, or water entering the exhaust system. Our inspection will confirm if the riser or elbow needs replacement before serious engine damage occurs.

Can I replace just the riser or do I need the whole exhaust system?

In most cases, only the exhaust riser and/or elbow need replacement. We inspect the entire exhaust system to ensure other components are sound, and we replace only what is necessary to restore proper function and prevent future leaks.

What type of parts do you use for replacements?

We use high-quality, marine-grade stainless steel or corrosion-resistant components that meet or exceed OEM specifications. This ensures long-lasting performance even in harsh saltwater conditions.

Do you test the exhaust system after replacement?

Yes, after installation we pressure-test and inspect the exhaust system for leaks, proper alignment, and correct engine function. This guarantees safety, prevents water intrusion, and ensures optimal engine performance.

How long does an exhaust riser replacement usually take?

The replacement typically takes 2–4 hours, depending on the boat type and engine configuration. We also perform a full system check after replacement to make sure your engine runs safely and efficiently.
