A Buyers Guide to Trailerboat Diesel Sterndrives
FNM marine diesel engines, in natural aspirated, turbocharged or turbocharged and inter-cooled configuration, common rail and Multi-jet, are real winners for their high specific power and specific torque with low specific fuel consumption, aside from having outstanding power-to-weight ratio and compact dimensions. The FNM HPE Series is based on Alfa Romeo diesel engine technology.
The FNM range has been topped off by the new HPE 250, 247hp (184kW), five-cylinder model based on the industry-acclaimed Alfa Romeo 2.4 litre Multi-jet 5-valve-per-cylinder turbo diesel aftercooled engine. This direct injection engine offers outstanding fuel efficiency and performance. The state-of-the-art Multi-jet system contributes to reduced exhaust emissions (RCD compliant) and clean running. Cutting edge technology delivers pinned-to-the-seat power, and reliability. The HPE 250 is fitted with a choice of industry-leading gearboxes (Twin Disc, ZF Hurth) and sterndrives (MerCruiser Bravo sterndrives).
The FNM HPE 250 delivers high torque (494Nm at 2800 rpm) and its compact lightweight design makes it eminently suitable for 6-8m trailerboats. All engines feature a panel instrument with VDO gauges that monitor oil pressure, engine and exhaust temperatures.
Due to be released later this year is a new four-cylinder engine, available in 100hp and 165hp configurations from Lees Group.
