Time to replace your Yanmar 4LV engine?
Looking for a straightforward and cost-effective replacement for your Yanmar 4LV? The Nanni T4/Z4 EVO3 offers an excellent alternative, whether your existing Yanmar engine is installed with a stern drive, jet drive or conventional shaft-line system.
Available in four power ratings – 150, 175, 225 and 260hp – the Nanni T4/Z4 EVO3 provides a flexible solution for a wide range of marine applications, from leisure craft and high-performance boats through to more demanding commercial installations.
One of the key advantages when replacing a Yanmar 4LV is the similarity in the installation connections. The Nanni’s exhaust outlet, raw-water inlet and fuel connections are the same size as those used on the Yanmar 4LV, with their locations also positioned in a similar area on the engine.
This can significantly simplify the replacement process, potentially reducing the amount of modification required to existing pipework and connections. For boat owners, this means a more straightforward installation, reduced installation time and potentially lower conversion costs.
With the Nanni T4/Z4 EVO3, replacing your Yanmar 4LV doesn’t necessarily mean starting again from scratch. In many installations, the similarities between the two engines can help make the transition to a new power unit simple, practical and cost-effective.



The weights and dimensions of the engines are similar. The Yanmar feet centres are just 4mm wider than the Nanni. Bespoke mounting options are also available for the Nanni engine.
