Engine/Gearbox for Swan 38 Good morning and happy to new year to all. We replaced some years ago the original engine bukh DV20 by a NANNI N4.38 with a HBW100 gearbox. This gearbox seems similat to ZF10M, now discontinued, and appears to be too "light" for the torque of the engine. I am planning to replace it by a ZF12M or ZF15M / MA. Has anyone already checked these solutions ? Thank you very much SWAN 38 PIZCO / hull 31

Engine/Gearbox for Swan 38

Good morning and happy to new year to all.

We replaced some years ago the original engine bukh DV20 by a NANNI N4.38 with a HBW100 gearbox.

This gearbox seems similat to ZF10M, now discontinued, and appears to be too "light" for the torque of the engine.

I am planning to replace it by a ZF12M or ZF15M / MA.

Has anyone already checked these solutions ?

Thank you very much
