Today, we completed a full service on a 30’ Mainship powered by twin Yanmar diesel engines and a Kubota marine generator for a Fort Myers customer. Keeping both propulsion and auxiliary power systems in top shape is essential for reliable cruising in Southwest Florida waters.
Twin Yanmar Diesel Engine Service
Our Yanmar service included:
- Engine oil and filter changes on both diesels
- Fuel filter replacements and inspection of fuel lines for leaks or wear
- Water pump service, including impeller replacement for proper cooling
- Belt inspection and replacement where needed for correct tension and reliability
- Gear oil inspection and replacement to protect the driveline
- Complete cooling system check for both raw water and closed-loop systems
- Thorough engine room inspection for leaks, corrosion, or loose fittings
Kubota Generator Service
For the Kubota marine generator, we performed:
- Oil and filter change for optimal performance
- Fuel filter replacement to ensure clean fuel delivery
- Water pump inspection and maintenance
- Belt inspection and adjustment for smooth operation
Raw Water Strainer Cleaning
We also removed and cleaned all raw water strainers for both the Yanmar engines and the Kubota generator. This is a critical step to keep debris out of the cooling system, ensuring clean water flow and preventing overheating.
Once all services were complete, we ran both the main engines and the generator under load to confirm smooth operation, proper temperatures, and clean exhaust.
At Island Marine Repair LLC, we use only OEM parts and premium marine-grade lubricants to meet manufacturer specifications. Our mobile marine service means we come to you — whether at your home dock or marina — so you can get back on the water faster.
