Sunseeker publishes the 76 Yacht with shaft propulsion and twin MAN V12 engines at either 1,400 PS or 1,550 PS each. Its brochure also states generator capacity of 27 kW at 50 Hz or 20 kW at 60 Hz. LADY M is a 2019 Sunseeker 76 in the Bluebnc managed fleet, listed at 3,100 HP with stabilisers at anchor and underway.

Engines (published)

2 x MAN V12, 1,400 or 1,550 PS (published options)

Conventional shafts

Stabilisation

Stabilisers at anchor and underway, listed for LADY M

First checks on this model

• Inspect both MAN V12 cooling circuits, seawater pumps, heat exchangers and exhaust elbows for restricted flow, leakage, corrosion and heat damage.
• Check gearboxes, couplings, shaft seals, cutless bearings, propellers and rudders, then measure alignment and record vibration under comparable load conditions.
• Run the stabilisers underway and at anchor, checking fin response, hydraulic pressure, seal leakage, controller alarms and cooling performance.
• Load-test the generator installation, checking seawater flow, exhaust condition, fuel delivery, battery charging and shore-power transfer under realistic demand.

The 95 Yacht has shaft drives, with Sunseeker publishing MTU power up to 4,002 PS; model reference data specifies twin MTU 12V 2000 M96L engines at 1,920 hp each. BLUE INFINITY ONE is a 2022 Sunseeker 95 in the Bluebnc managed fleet, listed at 28 m, 4,000 HP and 12,000 litres of fuel. Its listing also records zero-speed stabilisers.

Stabilisation

Zero-speed stabilisers, listed for BLUE INFINITY ONE

First checks on this model

• Read both MTU 12V 2000 M96L diagnostic histories, then compare temperatures, boost pressure, fuel delivery and load balance during a controlled trial.
• Inspect gearbox mounts, couplings, shaft seals, bearings, propellers and rudders, recording alignment measurements and vibration levels before planning corrective shaft-line work.
• Cycle the zero-speed stabilisers through their operating modes, checking fin movement, hydraulic pressure, seal condition, cooling, electrical supply and controller alarms.
• Clean and inspect the MTU seawater strainers, pumps, charge-air coolers, heat exchangers and exhaust injection points, then verify temperatures at sustained load.

Published specifications change with build year and options. Before ordering parts we confirm engine, drive and equipment serial numbers on board.

1. 01

   Main engines

   On the 76 Yacht, start with MAN V12 fault history, operating temperatures, fuel filtration, oil condition and cooling-water flow. The 95 Yacht requires the corresponding MTU diagnostic path. Load balance between engines matters on both models, as unequal boost, fuel delivery or cooling performance can indicate a developing fault before an alarm becomes persistent.

2. 02

   Shaft propulsion

   Both models use conventional shafts. Initial checks cover gearbox mounts, couplings, shaft seals, cutless bearings, propeller condition, rudder movement and anodes. Reported vibration should be recorded against engine speed, vessel speed and load before alignment work begins. This separates engine-related vibration from damaged running gear, bearing wear or a shaft-line alignment problem.

3. 03

   Stabiliser systems

   LADY M is listed with stabilisers at anchor and underway, while BLUE INFINITY ONE is listed with zero-speed stabilisers. Engineers first review controller alarms and operating behaviour, then inspect fin response, external seal areas, hydraulic pressure, hoses, cooling and electrical supply. Slow movement, overheating or uneven deployment should be investigated before continued operation.

4. 04

   Cooling and HVAC

   Warm Mallorca sea water raises the load on engine heat exchangers, exhaust injection systems and air-conditioning condensers. Engineers first inspect strainers for Posidonia and sand, then check pump output, hose condition, temperature differentials and alarm history. Restricted seawater flow can affect propulsion machinery, generators and chillers, particularly during sustained summer operation.
