We service all major marine diesel brands including Cummins, Caterpillar, Volvo Penta, Perkins, Westerbeke, Yanmar, MAN, MTU, Detroit Diesel, Lehman, and Universal, plus generators from Onan, Northern Lights, Westerbeke, and more. We're also an authorized dealer for Rehlko and Whisper Power generators.

Most of our work is dockside — we come to your slip anywhere in the San Diego area. For larger jobs like engine removal or major overhauls, we'll coordinate haul-out or shop work as needed. Either way, start with a service request and we'll figure out the right approach for your job.

We're based in National City and serve the greater San Diego area — all the bays and marinas from Oceanside down to Chula Vista, including Shelter Island, Harbor Island, Mission Bay, and Coronado.

Smoke color is a useful first clue. White smoke often points to unburned fuel, water intrusion, or low compression. Blue smoke usually means burning oil. Black smoke suggests overfueling, air restriction, or overloading — often a prop or turbo issue. Grey haze can indicate injector or combustion issues. Any persistent smoke is worth a diagnosis before it becomes an expensive problem.

First, check your raw water intake: a fouled strainer, blocked through-hull, or failed impeller causes most overheats. If those look good, the problem may be in the heat exchanger, thermostat, or exhaust elbow. Shut down before temperatures climb into the danger zone — running an overheating diesel can cause serious damage. If it keeps happening, have us take a look.

For most recreational boats: oil and filter changes every 100–250 hours (or annually at minimum), fuel filters annually or as needed, impellers every 1–2 years, coolant every 2–3 years, and valve adjustments per your engine's manual. Generators follow similar intervals based on hours. We can set up a maintenance schedule tailored to your engine and how you use the boat.

An engine survey is a thorough professional assessment of an engine's condition — visual inspection, running tests, sea trial data, and often oil analysis. You'd typically want one when buying a used boat (a hull survey doesn't cover the machinery in depth), before a major cruise, or when planning whether to repair or repower. We provide detailed written reports you can use for purchase decisions or insurance.

Yes — marine generator service is a core part of our business. We service Onan, Northern Lights, Westerbeke, Kohler, and more, and we're an authorized dealer for Rehlko and Whisper Power, which means factory-backed sales, installation, and warranty support.

Authorized dealers protect your warranty, install to factory spec with genuine OEM parts, provide ongoing factory-backed support, and can help you size the right unit for your boat. Gray-market or self-installed units often have limited or voided warranty coverage.

Yes. Whether your old engine has reached the end of its life or you want more reliability and efficiency, we can help you evaluate repower options, select the right engine, and handle the full installation. It starts with a conversation about your boat and how you use it.

Check the basics first: battery charge and connections, fuel level and valves, and that your stop control isn't engaged. A diesel that cranks but won't fire usually has a fuel delivery or air problem; one that won't crank is typically electrical. If the basics check out, give us a call — describe what it does (clicks, cranks slowly, cranks strong but no fire) and we can often narrow it down over the phone.
