Comprehensive Maintenance for Marine Diesel Systems

Marine diesel engines are the workhorses of the fleet, requiring consistent attention to fuel quality and cooling efficiency. At Bayside Boatworks, we provide professional service for major marine diesel brands, including Yanmar, Cummins, Volvo Penta, Caterpillar, and Westerbeke. Our maintenance programs cover everything from oil and primary/secondary fuel filter changes to heat exchanger descaling and raw water pump impeller replacement. By staying ahead of factory service intervals, we help you avoid the costly "no-start" or overheating issues often caused by salt-air corrosion and fuel contamination.

Diagnostics, Troubleshooting, and Mechanical Repairs

If you are noticing excessive smoke, overheating, or a drop in RPMs, our mobile team is equipped to perform on-site diagnostics to identify the issue before it leads to a major failure. We specialize in cooling system flushes, fuel injector inspections, and belt tension adjustments. We also handle turbocharger inspections, transmission fluid changes, and exhaust riser replacements.
