Should I rebuild or repower my diesel engine?

It depends on the engine's condition, its hours and what parts for it cost. We check compression, the fuel and cooling systems and the oil, then give you a written estimate for each option, so you can compare a rebuild with a replacement engine before anything is done.

What is the difference between repairing a diesel engine and rebuilding it?

A repair fixes the part that failed, such as an injector, a pump or a gasket. A rebuild takes the engine apart and renews its worn internal parts, such as rings, bearings and gaskets, with any machining done by a machine shop. We tell you which one your engine needs after the diagnosis, with a written estimate.

How much does a diesel engine overhaul cost?

Labor is $150 an hour, plus parts and the trip fee for work at your boat. A diagnosis is at least $300 for each engine; then you get a written estimate for the repair, and nothing is done without your OK.

Do you check the cooling system during an overhaul?

Yes. Overheating is often caused by a clogged raw-water intake or strainer, a worn impeller or a stuck thermostat. We check the whole cooling system, find the cause and quote the repair before we do it.

Can the overhaul be done with the boat at my dock?

Yes. Whether your boat is in the water or on a trailer, we come to you in San Pedro, Wilmington, Long Beach, Redondo Beach, Seal Beach, Huntington Harbour, Marina del Rey and Newport Beach; farther places on request. Each visit has a one-way trip fee by distance, from $30 in San Pedro to $110 in Newport Beach.

Can you bring back a diesel engine that has been sitting for years?

Often, yes. We start with a compression test and a check of the fuel, starting and cooling systems, then tell you what can be repaired and what needs replacing, with a written estimate. Old fuel is drained and disposed of, and the fuel system cleaned, before the engine is started.

What if the starter engages but the engine will not turn at all?

That usually points to a weak battery or a poor connection, a starter that has failed, or an engine that is seized or has water in a cylinder. Do not keep cranking it: we test the batteries, cables and starter and check whether the engine turns by hand, then give you a written estimate for the repair.

About this service

Marine Engine Repair in Long Beach and San Pedro

We diagnose and repair inboard and outboard boat engines, gasoline and diesel, at your slip, dock or storage yard from Marina del Rey to Newport Beach, or at our San Pedro shop. We work on Mercury, MerCruiser, Yamaha, Volvo Penta, Indmar, Yanmar and Cummins engines.

What the work covers

Marine engine repair starts with finding the cause, so we work through the engine in order before we replace anything:

Fuel: filters, water separators, pumps, carburetors or injectors, and the condition of the fuel itself.
Ignition: spark plugs, wires, coils and timing on gasoline engines.
Compression: a compression test shows the condition of the rings, valves and head gaskets.
Cooling: water flow, impeller, thermostats and exhaust risers. For an engine that runs hot, see overheating diagnosis and a cooling system flush.
Electronics: on fuel-injected and electronically controlled engines, ECM scanning reads stored fault codes and live sensor data.

Once we know the cause, we quote the repair before any work is done, and parts are quoted with the job. After the repair we run the engine to confirm the fix. A sea trial shows problems that only appear under load.

When to call

Hard starting, or no start at all
Stalling at idle or when you shift into gear
Misfiring, surging or hesitation under throttle
Lower top RPM than normal
A warning light, an alarm or a fault code on the display
Smoke, a new knock or tick, or a fuel smell (with a fuel smell, ventilate and do not start the engine)

Questions about marine engine repair

Do you repair diesel engines?

Yes. Many inboards on larger boats and yachts are diesels, and we work on Yanmar, Cummins and Volvo Penta diesels as well as gasoline engines. When a diesel is worn past repair, see diesel engine rebuilds.

What should I tell you when I book?

The engine make and model, the approximate hours, when it was last serviced and what it does. Say when the problem shows up: cold or hot, at idle or under load. If the display shows a fault code, a photo of it helps.

Book a visit: submit a ticket with the boat, where it is kept and what the engine is doing, or call (213) 693-0224.
