ZF is extending its pod propulsion range with the launch of its new POD 4900 at the Cannes Yachting Festival.
The new model is designed for larger commercial and recreational vessels measuring up to 150ft and is compatible with engines up to 2,000hp at 2,450rpm.
The POD 4900 will first launch onboard the Azimut Grande 30M superyacht as part of an integrated power pack by Rolls-Royce Power Systems with two units delivering 1,920hp each.
ZF first unveiled its first pod propulsion system, the POD 4600, at the Cannes Yachting Festival in 2022 and since launch, the company has delivered more than 30 systems to shipyards worldwide.
Azimut’s vessels have been a great showcase for our pod propulsion’s unique strengths.

“This means that this year’s show marks the perfect occasion to introduce our new POD 4900”, says Federico Decio, head of business unit marine and special driveline technology.
The POD 4900 extends the power range upwards providing a maximum of 6,107 Nm of input torque, and a typical speed range of 20 to 35 knots.
“With these specs, our product is uniquely suited for ships where both powerful performance and high maneuverability are key,” added Federico.
“Azimut’s vessels have been a great showcase for our pod propulsion’s unique strengths.
“After our initial project back in 2022 with the POD 4600 in the Azimut Grande 26M, we are more than happy to continue this path of innovation with the new POD 4900.”
Integrators for marine applications
He continued: “We are also delighted to see the results of our close partnership with Rolls-Royce Power Systems.
“Their invaluable experience as integrators for marine applications brings unmatched performance to the new superyacht.”
The POD 4900 system can be installed in a twin, triple, or quadruple layout depending on the vessel.
The system’s gear reduction ratio of 2,434-2,612 allows for larger counter-rotating propellers with the aim of increasing its efficiency.
The system has a steering angle of +30 degrees/-30 degrees and is integrated with ZF’s TotalCommand and Joystick steering solutions.
Optimised hydrodynamic design
As with the POD 4600, the POD 4900 features an optimised hydrodynamic design with a nickel aluminum bronze and stainless steel corrosion-resistant housing.
The POD 4900 is certified for up to 3,000 hours of operations per year.
“The ZF POD gives us the opportunity to make the best possible use of our high-performance, efficient mtu engine, significantly reducing fuel consumption and improving maneuverability,” said Denise Kurtulus, senior vice president global marine, Rolls-Royce Power Systems.
“The system we have integrated and coordinated is the ideal combination because it is more than just the sum of its components.”
