Engine Overhaul
& Rebuild

When your engine has reached the end of its service life, a proper overhaul is the most cost-effective path to a reliable, long-lasting powerplant. We perform complete marine diesel engine overhauls to manufacturer specifications using only OEM or equivalent quality parts.

Our process begins with a full disassembly and inspection to document every component’s condition, followed by a detailed written estimate before any parts are ordered.

  • Complete engine disassembly, inspection, and measurement
  • Block boring, honing, and resurfacing as required
  • Crankshaft grinding, polishing, and bearing fitment
  • New pistons, rings, bearings, gaskets, and seals throughout
  • Valve train reconditioning and head work
  • Full reassembly to factory torque specs
  • Break-in procedure and sea trial before delivery
Service 02

Injection Pump
& Injectors

The fuel injection system is the heart of your diesel engine’s performance and efficiency. Worn injection pumps or fouled injectors cause hard starting, black smoke, poor fuel economy, and engine damage.

We use precision test equipment to verify injection pressure, timing, and spray pattern across all major marine engine brands — both mechanical and electronic systems.

  • Injection pump removal, testing, rebuild, and calibration
  • Injector flow testing, cleaning, and reconditioning
  • Injection timing verification and adjustment
  • Fuel system bleed and pressure testing
  • Electronic fuel system diagnostics (Cummins, Yanmar, CAT)

  • Heat exchanger inspection, cleaning, re-coring, or replacement

Engine
Survey

An engine survey gives buyers, sellers, and insurers an independent, factory-level assessment of a marine diesel or generator — mechanical condition, electronic health, and true performance under load. A hull survey rarely tells the full story about the machinery; this closes that gap.

Every survey is run on the manufacturer’s own diagnostic tooling and backed by lab fluid analysis, then compiled into a photo-supported written report with graded findings, prioritized deficiencies, and honest cost and service-life estimates.

  • Full mechanical inspection — leaks, mounts, belts, hoses, and wiring
  • Cylinder compression and leak-down testing
  • Factory diagnostic scan, fault codes, and engine-hours verification
  • Cooling, fuel, and exhaust system evaluation
  • Sea trial — temperatures, pressures, and behavior at rated RPM
  • Spectrographic engine-oil and coolant analysis
  • Written report with photos, findings, and recommendations

Why It Matters

Why Buy From an
Authorized Dealer

Warranty Protected
Purchasing through an authorized dealer ensures your full manufacturer’s warranty is in place. All warranty service is performed by factory-certified technicians using genuine OEM parts.
Expert Installation
Proper generator installation requires detailed knowledge of fuel systems, exhaust routing, electrical integration, and vibration isolation. Our technicians have performed dozens of marine generator installations.
Ongoing Support
As your authorized dealer, we’re your long-term service partner — not just the initial sale. We provide scheduled maintenance, genuine parts, and technical support for the life of your generator.
Genuine OEM Parts
Aftermarket parts can void warranties and compromise reliability. We stock and use only genuine manufacturer parts on every service and repair.
Right-Sizing Advice
Choosing the correct generator size for your vessel is critical for efficiency and longevity. We assess your electrical loads, space constraints, and usage patterns to recommend the right model.
Marine-Only Expertise
We work exclusively in the marine environment. We understand the unique demands of saltwater, vibration, and space constraints that separate marine generator installation from any other application.

The Early Years — Cleveland, OH
A Lifelong Tinkerer
Todd grew up in Cleveland, Ohio with grease under his fingernails before most kids had a job. By age 12 he was already tearing into small engines — mopeds, snowblowers, lawn mowers — teaching himself how mechanical things work the only way that really sticks: hands on. That curiosity never left him.
2000 – 2003 — UTI & Honda Certification
Formal Training, Factory Certified
After graduating high school in 2000, Todd enrolled at Universal Technical Institute (UTI) to put a formal foundation under everything he’d already taught himself. He graduated in 2003 with Honda motorcycle certification in hand and immediately relocated to San Diego — a city built for people who love the water, the road, and the outdoors.
2003 – 2012 — San Diego BMW Motorcycles
BMW Master Tech & Racing
Todd joined San Diego BMW Motorcycles (formerly Brattin BMW) and worked his way up to Master Certification — the highest technical level BMW awards. Alongside his shop work he served as mechanic for the SD BMW AMA Superbike race team and took on a range of outside motorsport projects, building a reputation for precision under pressure.
2012 – Present — The Marine World
From Two Wheels to the Water
In 2012, a conversation with a close friend who shared his love of riding and boating opened an unexpected door into the marine industry — and Todd never looked back. He pursued factory training with Yanmar Marine, Rehlko (formerly Kohler) Marine Generators, and Whisper Power, building the expertise to diagnose and repair complex electrical and mechanical systems across every make and model of marine diesel and generator. Endurance Marine was born from that foundation.
The Personal Side
Boater, Father, Athlete
When he’s not in the engine room, Todd is out on the water aboard his own Carver 370 Voyager berthed at Humphreys Half Moon Marina. He’s happily married with two daughters who share his love of boating. Off the water, Todd pushes himself in ultramarathon running and competitive downhill mountain bike racing — the same drive for precision and endurance that defines his work.
“
I’ve been taking things apart since I was 12 years old. The tools got bigger and the engines got more complex, but the approach never changed — understand it completely, fix it right, and leave it better than you found it.

Endurance Marine Diesel Inc. ("we," "us") operates this website to tell you about our marine diesel and generator services in San Diego. This page explains what information we collect when you visit, and how we use it. The short version: we collect very little, we don't sell anything about you, and we use standard tools to understand how the site is used so we can make it better.

Information You Give Us

If you request service through our website, call us, or email us, we collect the contact and vessel details you provide — typically your name, phone number, email, boat information, and a description of the work needed. We use this solely to respond to you, schedule and perform service, and keep records of work performed. Service requests submitted through the site are processed by Jobber, the field-service platform we use to manage jobs and invoicing.

Information Collected Automatically

Like most websites, we use analytics tools to understand how visitors use the site. This site uses Microsoft Clarity, which captures how you interact with pages — including mouse movement, scrolling, clicks, and session replays — along with technical data such as device type, browser, and general location. We use this to see which pages work well and which need improvement. Clarity uses cookies and similar technologies to do this; you can learn more in the Microsoft Privacy Statement. Our hosting provider (Netlify) also keeps standard server logs, and embedded services such as Google Maps and Google Fonts may set their own cookies when those elements load.

How We Use Information

We use the information described above to provide and schedule marine services, respond to inquiries, maintain service records, and improve this website. We do not sell your personal information, and we do not use it for third-party advertising. We share information only with the service providers named above (Jobber, Microsoft, Netlify, Google) as needed to operate the site and our business, or if required by law.

Your Choices

You can block or delete cookies in your browser settings, and most browsers offer private-browsing modes that limit tracking. If you'd like us to update or delete contact information we hold about you, just ask — call or email us and we'll take care of it.
