Maintaining a “new-to-you” vessel like a Beneteau 321 requires a sharp eye, especially when dealing with the reliable but precise Perkins M30 (28 hp) diesel engine. If you recently purchased your boat (around August 2024) and are noticing coolant loss or unusual smoke, it’s time for a professional diagnostic to ensure your investment stays seaworthy.
At Yes Centers, we provide expert marine diesel services throughout Kemah and the surrounding 30-mile radius, helping sailors from Seabrook to Galveston keep their engines running cool and clean.
Essential Maintenance for the Perkins M30 Diesel
The Perkins M30 is a workhorse, but like any marine diesel, it requires consistent upkeep to prevent mid-bay breakdowns. Whether you are prepping for a weekend at Redfish Island or a longer coastal cruise, here is how we approach a comprehensive engine “health check.”
1. Professional Oil & Filter Service
Even if you already have the oil and filters on hand, having a professional perform the change ensures that the old oil is analyzed for signs of internal wear (like metal shavings or fuel dilution). For a boat purchased in late 2024, a fresh baseline for all filters—fuel, oil, and air—is critical for reliable performance.
2. Comprehensive Drive & Transmission Inspection
It isn’t just about the engine. A thorough inspection includes:
Transmission: Checking fluid levels, shift cable tension, and looking for leaks.
Drive Components: Inspecting the stuffing box/shaft seal, engine mounts, and alignment.
Cooling System: Checking the raw water impeller and heat exchanger for scale buildup.
3. Investigating Coolant Loss & Engine Smoke
Losing “radiator” fluid (coolant) and seeing smoke after a refill is a specific symptom that requires immediate investigation. In our local Texas coastal waters, heat is the enemy. We look for:
Heat Exchanger Leaks: Internal leaks can allow coolant to escape through the exhaust.
Head Gasket Integrity: Smoke and fluid loss can sometimes indicate a breach.
Air Pockets: If smoke appears specifically after filling, we check if the system was properly bled or if a leak is causing the engine to run lean.
