Pair With Your Existing Sterndrive

Sterndrive propulsion systems offer a host of benefits, including:

NANNI offers a range of diesel engines that are perfectly suited for sterndrive applications. They integrate seamlessly with popular sterndrive systems such as Mercury’s Mercruiser Bravo X drives. We also offer adaption packages to fit with existing sterndrives, and on commercial boats, NANNI can connect with Konrad drives.


From Petrol to Diesel: Installing a NANNI Z4.270

A Mustang 2400 powerboat motors across the open ocean

When this old Mustang 2400 was repowered from petrol to diesel, the new NANNI T4.270 worked perfectly with the existing Mercuiser Bravo Three X sterndrive configuration.

Following the installation of the NANNI engine, the Mustang saw a fuel saving of 40%. Besides reduced operation costs, the vessel’s operating range is extended with the same 200-litre fuel tank.
