Marine Engines 20HPE

Inboard Marine Engines

Models: 20HPE 180 - 20HPE 150 - 20HPE 120

FNM® 4-cylinder 20HPE marine engine is based on the new 2LT Multijet engine, that equips a large number of small and medium size cars in Europe.

The engine uses a common-rail fuel injection system controlled by an ECU (Electronic Control Unit), especially made for it.

The engine is small and powerful, its wide distribution is the proof of its reliability and wide availability of spare parts.

ECU (Electronic Control Unit)

ECU has been developed entirely in house
This unit guarantees excellent performances with low emissions
It has been conceived after a 10-year development project carried out by R&D team
It is especially designed for HPE marine engines application
It controls Bosch common rail system parts
It includes unique control stategies as: anti-shutdown in situations of gear engagement for installations with high inertia or rapid gear changes

First class Performance

Unparalled perfomances in each operating condition:

The engine reaches up to 129kW (175HP)

The engine can achieve up to 3000h/year
