Evaluating Engine Condition and Hours
Check Running Hours and Maintenance History
Low hours and complete service records are strong indicators of longevity. Ask for logs showing changes of oil, filters, and coolant, as well as any major overhauls or component upgrades.
Look for Rust and Wiring Condition
Inspect for corrosion on the housing, mounting brackets, and electrical terminals. Clean, organized wiring with proper chafing protection suggests a well cared for unit, while fresh paint and professional labels can signal a refurbishment.
Understanding Power Needs and Compatibility
Match Generator Output to Boat Systems
Calculate the running watts of your essential loads, including HVAC, refrigeration, water heaters, and electronics. Choose a Westerbeke marine generator for sale craigslist unit with a continuous rating that exceeds your total load by at least 20 to 30 percent for safety and motor surge currents.
Verify Voltage and Phase Configuration
Most modern boats use 120/240 volt split phase power, but some larger vessels require 208Y/120 volt three phase. Confirm that the generator output matches your boat panel and that you have the correct transfer switch or breaker setup.
Assessing Fuel Systems and Run Time
Compare Diesel vs Gasoline Options
Diesel Westerbeke generators typically offer better fuel efficiency, longer service intervals, and safer energy density. On craigslist, diesel models often have a higher upfront price but lower cost per hour over the life of the engine.
Estimate Practical Run Time with Tank Size
Use the fuel tank capacity and manufacturer rated fuel consumption to estimate hours at typical load. Factor in alternator charge current for house batteries, as charging loads can noticeably affect overall fuel economy and available auxiliary power.
Navigating Craigslist Listings Safely
Screen Seller Profile and Communication
Prefer sellers with detailed history, multiple listings, and prompt replies. Review feedback if available, and prioritize listings with clear photos, honest descriptions, and documented maintenance rather than vague promises.
Arrange Transport and Test Before Paying
Confirm pickup or delivery logistics, trailer capacity, and road legal requirements before committing. Whenever possible, test the generator on load to verify rated output, stable voltage, and absence of unusual noise or excessive smoke.

FAQ
Reader questions
How can I verify that a Westerbeke generator listed on craigslist is genuine and not relabeled?
Check the serial number against Westerbeke records if possible, inspect OEM badges and casting marks, and look for factory documentation or original dealer tags. A mismatched serial format or generic stainless nameplate can be a red flag for repowering or relabeling.
What should I do if the listing mentions the generator was removed from another boat?
Ask for removal photos, prior installation details, and the reason for removal. Confirm that the load was balanced and whether the unit ever operated with modern electronics, as some older boats had lighter loads that do not reflect real world usage on current vessels.
Is it safe to buy a Westerbeke generator for sale craigslist without service records?
It can be safe if the unit is inspected carefully, runs reliably on test, and shows minimal wear. Budget for a professional service refresh, including oil, filters, hoses, and a compression check, to reduce the risk of hidden wear or fatigue in critical components.
Can I use a Westerbeke marine generator to power a dockside battery bank at the marina?
Yes, you can use the generator to charge house batteries while at the dock, but verify the charging setpoint matches your battery type and that the shore power isolator is wired for safe operation. Use a quality surge protector and monitor temperature and belt wear during extended charging sessions.
