BENEFITS OF REPOWERING YOUR MARINE DIESEL ENGINE

REDUCING THE EMISSION OF POLLUTANTS:
    • The need to reduce engine emissions is often the key driver for repowering boats. This need could be driven by new emission regulations or emerging customer, owner or governmental demands.
IMPROVING FUEL ECONOMY:
    • Offers dual benefits of a reduced environmental footprint and lower cost. Improved fuel economy and a lower total cost of ownership is often a key goal of repower for commercial vessels ranging from tugs to fishing boats.
INCREASING CRUISE SPEED:
    • A common repower goal for vessels that generate revenue by shuttling back and forth on a route. These could be passenger ferries, commuter boats, offshore support vessels and beyond.
REDUCING NOISE AND VIBRATION:
    • For boats that have people as their primary source of income, providing a comfortable and quiet ride is key. Operators of water taxis, dinner cruises, tour boats, crew boats and river cruises can turn reduced noise and vibration into quantifiable financial gains.
INCREASING RELIABILITY:
    • This is a common repower goal among different types of vessels. For commercial vessels, the financial cost of downtime makes reliability an important consideration during repowers. If a boat is on the hard or in port waiting on parts or a service technician, it is not making money. In addition, minimizing the unplanned nature of downtimes is another goal of repowers, especially during a time when constrained supply chains could result in longer lead times for parts needed.
BETTER TOTAL COST OF OWNERSHIP:
    • For many commercial vessels, this is a key consideration during a repower. Things that factor into TCO include the upfront price of the engine, fuel economy as mentioned above, midlife service, and parts pricing.
