Question 1

Do generator repairs come with a warranty?

Lukas · Accepted Answer

Yes, all generator diagnostics and repairs come with a 3–12 month labor warranty. OEM replacement parts include manufacturer warranties. We also provide a detailed service report with diagnostic findings and recommendations.

Question 2

Do you offer emergency marine generator repair?

Lukas · Accepted Answer

Yes – we offer emergency dockside generator service for non-starting units, power loss, or fuel delivery issues. Contact us 24/7 if your generator fails while onboard or underway.

Question 3

Can you test load and voltage output during diagnostics?

Lukas · Accepted Answer

Absolutely. We perform full load testing, voltage and frequency analysis, and simulate real onboard conditions to ensure your generator delivers stable power under demand.

Question 4

How much does generator repair usually cost?

Lukas · Accepted Answer

Diagnostics typically start at $250. Repairs range from $300 to $1,200 depending on the issue — fuel system, wiring, control panel, or cooling system. We always provide an estimate before starting.

Question 5

Do you service both diesel and gasoline marine generators?

Lukas · Accepted Answer

Yes – we service diesel and gas-powered marine generators, including Kohler, Onan, Northern Lights, Westerbeke, and more. Whether it’s a startup issue or poor voltage, we can help.

Question 6

What are signs that my generator needs repair?

Lukas · Accepted Answer

Common symptoms include trouble starting, surging power, overheating, strange noises, or frequent shutdowns. If your generator shows any of these signs, it’s time for a diagnostic check.

Question 7

Can you flush and clean the cooling system during repair?

Lukas · Accepted Answer

Yes – we perform full coolant flushes, clean raw water strainers, and descale heat exchangers. A clean cooling system helps prevent overheating and prolongs generator life.

Question 8

Why does my marine generator need regular oil and filter service?

Fryderyk Florczak · Accepted Answer

Regular oil and filter changes keep your marine generator properly lubricated and free of contaminants. This prevents premature engine wear, improves efficiency, and ensures reliable power when you need it most—especially during long trips or overnight stays.

Question 9

How often should generator oil, filters, and impellers be replaced?

Fryderyk Florczak · Accepted Answer

Most marine generators require oil and filter service every 100 hours or once per season. Raw water impellers should typically be replaced annually or sooner if the generator runs frequently or in warm saltwater conditions.

Question 10

What happens if the generator impeller is not replaced on time?

Fryderyk Florczak · Accepted Answer

A worn or failed impeller can restrict cooling water flow, causing the generator to overheat and shut down. In severe cases, it can lead to costly damage to the heat exchanger or exhaust system.

Question 11

What is included in your marine generator service?

Fryderyk Florczak · Accepted Answer

Our service includes draining and replacing engine oil, installing new oil and fuel filters, inspecting and replacing the raw water impeller, checking belts, hoses, and coolant flow, and performing a full operational test after service.

Question 12

Do you service all marine generator brands?

Fryderyk Florczak · Accepted Answer

Yes, we service most major marine generator brands including Kohler, Westerbeke, Northern Lights, Onan, and Fischer Panda. We use manufacturer-approved oils, filters, and impellers whenever possible.

Question 13

Can generator maintenance improve fuel efficiency and reliability?

Fryderyk Florczak · Accepted Answer

Absolutely. Clean oil, fresh filters, and a healthy impeller allow your generator to run cooler and more efficiently. Proper maintenance reduces fuel consumption and minimizes the risk of unexpected shutdowns while underway or at anchor.

Question 14

Do you provide documentation and warranty for generator service?

Fryderyk Florczak · Accepted Answer

Yes, all services include written documentation for maintenance records. Parts are covered by manufacturer warranties, and our labor includes a service warranty ranging from 3 to 12 months depending on the scope of work.

Question 15

What is generator heat exchanger descaling and why is it necessary?

Fryderyk Florczak · Accepted Answer

Heat exchanger descaling removes mineral deposits, salt buildup, and marine growth that restrict water flow. Regular descaling helps prevent generator overheating, improves cooling efficiency, and extends the life of the heat exchanger and generator.

Question 16

What are the signs that my generator heat exchanger needs descaling?

Fryderyk Florczak · Accepted Answer

Common symptoms include high generator temperature, reduced water discharge, frequent alarms, or automatic shutdowns. These issues often indicate restricted cooling passages caused by scale or debris.

Question 17

How often should generator heat exchangers be descaled?

Fryderyk Florczak · Accepted Answer

We recommend descaling every 1–2 years, depending on water conditions and usage hours. Boats operating in warm, saltwater environments like Newport Beach and Long Beach may require more frequent service.

Question 18

What does your heat exchanger descaling service include?

Fryderyk Florczak · Accepted Answer

Our service includes isolating the cooling circuit, circulating marine-safe descaling solution, flushing the system thoroughly, inspecting zinc anodes, and verifying proper cooling flow after service.

Question 19

Is descaling safe for my generator and cooling system?

Fryderyk Florczak · Accepted Answer

Yes. We use manufacturer-approved, marine-safe descaling solutions that effectively remove buildup without damaging seals, hoses, or internal components of the heat exchanger.

Question 20

Can descaling improve generator performance and reliability?

Fryderyk Florczak · Accepted Answer

Absolutely. Proper cooling reduces engine stress, prevents shutdowns, stabilizes operating temperature, and helps your generator run more efficiently and reliably during extended use.
