We understand you might have questions about maintaining your boat and choosing the right mechanic. Here are the things we get asked most often. Don't see yours? Give us a call.
Engine starting issues can stem from various problems — battery, fuel delivery, or electrical faults are the most common. We recommend scheduling a diagnostic so we can accurately identify and resolve the issue rather than guessing at parts.
Generally, engine oil should be changed annually or every 100 hours of operation, whichever comes first. Lower unit gear lube should also be checked and changed annually. Always refer to your engine manufacturer's recommendations for precise service intervals.
Our comprehensive winterization service typically includes stabilizing the fuel, fogging the engine, draining and refilling the lower unit, draining water systems, and protecting against freezing. This ensures your boat is safe from winter damage and ready for spring.
Boat owners often worry about a mechanic's technical competence, unpredictable costs, and long wait times. At PK Marine Service, we address these concerns head-on with experienced technicians, transparent pricing, and efficient scheduling to get you back on the water quickly.
The best advice we can give is to conduct regular check-ups and inspections on your boat. Here's a surprising fact: four times as many boats sink in their slips as do underway. Consistent vigilance prevents the kind of problems that ruin a season.
We understand that cost is a significant factor. We strive for transparent and competitive pricing, provide detailed estimates before starting any work, and communicate clearly about any unexpected issues. You're always informed before we proceed.
Absolutely. We're equipped to diagnose and repair a wide range of fuel-related problems — from contaminated fuel and clogged filters to issues with fuel pumps and injectors. Proper fuel system maintenance is crucial for optimal engine performance.
Yes. Marine electrical systems can be complex, and our technicians are skilled in troubleshooting and repairing all types of electrical issues — from faulty wiring and navigation light problems to marine electronics installations and diagnostics.
We stand behind our work. Specific warranty details vary by service and parts used. Discuss your specific repair with us and we'll gladly provide all warranty information relevant to your service.
Many boaters find themselves juggling multiple providers for winterization, electronics, and engine work.

We're also one of the few shops offering 24/7 emergency dockside support for our customers across the South Coast and East Bay.
