What We Do:

On-Site Service, Repairs & Maintenance

From annual mechanical maintenance to the most complex in-frame Diesel or Gas engine rebuilds, re-powering and generator upgrades, our team of professionals will be there to assist you with your application, repair, service, maintenance, or purchase and installation.

Expertise You Can Trust

For more than 35-years Diesel Systems Services has specialized in all major brands of marine diesel engines and generator systems up to 3,000 HP. Based in the Seattle area, our seasoned team of marine diesel mechanics are experts in mechanical surveys, mobile marine service, repair and maintenance of vessels up to 300 feet, sail or power.

Power Generator Service & Repair

Marine generators don’t have it easy. They labor away in tight, stifling corners of the engine room or lazarette and, all too often, are overlooked until something goes wrong. This is especially true if you are planning a summer cruise when the genset will rack up a fair number of hours powering the air conditioning and other on-board systems you can’t seem to live without.

Cooling Systems Diagnostic & Repair

Raw-water pumps are similar on almost all marine engines. Change rubber impellers every year or two at the very least. Waiting until one fails means having to work to find all the pieces, typically lodged in the seawater inlet of gas or diesel heat exchangers or in the thermostat housing of open-cooled gas engines

Wet Exhaust System Care

To transfer engine heat from antifreeze overboard, sea water or lake water routes through heat-exchanger tubes or plates immersed in the antifreeze. For boats in salt water, We suggest tearing down gas engine closed cooling systems about every three to five years, and diesels a bit sooner. Scale builds up in both the antifreeze and saltwater sides, which impedes heat transfer.

Fuel System Service

Big boat, small boat; old boat or new; single engine or triple outboards; your vessel’s fuel system is the critical link to make your inboard, I/O or outboard propulsion system reliable and functional when you are out on the briny. We will keep your boat’s fuel supply system in tip-top operating condition.

Major Mechanical Repairs & Rebuilds

Overhauls & Re-Powers

At times, Diesel Systems Services recommends engine overhauls rather than buying new.

In this case, we assess the cost verses benefits in rebuilding. We carefully determine what is in need of repair and what is not. This is where our expertise really counts; we provide cost-effective solutions when dealing with mechanical issues.

If our client chooses to rebuild the existing engine, we apply the latest technologies in restoring the original specifications and high performance it once had, complete with warranties and suggested preventive maintenance programs.

Diesel Systems Services is the best choice for all your engine overhaul needs.

We perform work on major marine brands such as: Detroit Diesel, CAT, Cummins, MTU, Ford, Volvo, and Hino.

Our knowledgeable diesel mechanics are always here to help assist and give technical advice when you need it most.
