309-578-2345 (Direct access to the pleasure craft assistance line.) 

Pleasure craft customers in Europe, Africa, and the Middle East can call: 

+41 (22) 849 9333 (Switzerland). 

coverage is 24 hours a day, 7 days a week. 

WArrANtY 

The standard warranty for all components on non-revenue producing pleasure craft 

applications is 24 months or 1000 hours (whichever occurs first) after delivery to the 

first user for C7 propulsion engines and 24 months after delivery to the first user for 

all other new propulsion engines. For 3056, C1.5, C2.2, and C4.4 generator sets the 

standard warranty is 24 months or 2000 hours (whichever occurs first) after delivery 

to the first user. An extended warranty period applies to new marine propulsion 

engines used in non-revenue producing pleasure craft applications and applies to 

major engine components. 

The extended warranty period for new C7 engines is 60 months or 2000 hours, 

whichever occurs first, after delivery. The extended warranty period for all other 

new marine propulsion engines used in non-revenue producing pleasure craft 

applications is 60 months after delivery. This warranty runs concurrently with the 

standard warranty period. For additional information, please refer to the Caterpillar 

warranty statement for marine products.

AtING DeFINItIONs 

Caterpillar ® marine engines are developed to perform to customer 

expectations in various applications. An understanding of the vessel’s 

intended use (load profile) allows the correct engine rating to be 

selected. The correct engine rating is more likely to provide the customer 

with engines that have an acceptable life to overhaul and good engine 

performance. Caterpillar marine engine ratings are determined by overall 

load profile, operational hours per year, and time spent at full throttle. 

A rating (unrestricted continuous) 

typical applications: For vessels operating at rated load and rated 

speed up to 100% of the time without interruption or load cycling (80% 

to 100% load factor). Typical applications could include but are not 

limited to vessels such as freighters, tugboats, bottom drag trawlers, 

or deep river tugboats. Typical operation ranges from 5000 to 8000 

hours per year. 

B rating (Heavy Duty) 


speed up to 80% of the time, or 10 hours out of 12, with some load 

cycling (40% to 80% load factor). Typical applications could include but 

are not limited to vessels such as mid-water trawlers, purse seiner, 

crew and supply boats, ferries, or towboats. Typical operation ranges 

from 3000 to 5000 hours per year. 

c rating (maximum continuous) 


speed up to 50% of the time, or 6 hours out of 12, with cyclical load and 

speed (20% to 80% load factor). Typical applications could include but 

are not limited to vessels such as ferries, harbor tugs, fishing boats, 

offshore service boats, displacement hull yachts, or short trip coastal 

freighters. Typical operation ranges from 2000 to 4000 hours per year. 

D rating (Intermittent Duty) 


speed up to 16% of the time, or 2 hours out of 12, (up to 50% load 

factor). Typical applications could include but are not limited to vessels 

such as offshore patrol boats, customs boats, police boats, some 

fishing boats, fireboats, or harbor tugs. Typical operation ranges from 

1000 to 3000 hours per year. 

e rating (High performance) 


speed up to 8% of the time, or 1/2 hour out of 6, (up to 30% load factor). 

Typical applications could include but are not limited to vessels such 

as pleasure craft, harbor patrol boats, harbor master boats, some 

fishing or patrol boats. Typical operation ranges from 250 to 1000 hours 

per year.

Acert tecHNOLOGY 

Consistent with their long history of technological innovation and 

progress, Caterpillar is continually investing in research and development. 

Over $500 million has been invested to meet today’s stringent emissions 

regulations and to offer the market a reliable product with the 

performance that meets the needs of customers worldwide. This latest 

evolution in the Caterpillar engine line is the introduction of ACERT 

Technology. Caterpillar draws on a wide range of product experience 

to develop these basic engine system innovations. As new engines are 

developed, specific ACERT Technology components are incorporated to 

reduce smoke and noise, provide better performance, and increase fuel 

efficiency. The four fundamental components are: 

electronics 

• The newest Cat ® ADEM electronic control module and proprietary 

software, developed specifically for each power rating and emissions 

level, allow ACERT engines to precisely control and shape fuel delivery, 

air management, and all other engine functions. 

Fuel Delivery 

• Multiple fuel injection delivery introduces fuel into the combustion 

chamber in a series of precisely timed “micro bursts.” This provides 

maximum power and fuel efficiency with minimum emission levels. 

Air management 

• Air management technologies such as cross flow cylinder heads, 

wastegate turbochargers, even variable valve timing can be 

incorporated to control combustion air, burn fuel more efficiently, and 

enhance performance. 

combustion 

• Combustion system design pulls the maximum amount of energy from 

fuel delivery and applies this energy to the propeller or generator. 

ACERT Technology combines proven systems with innovative new 

technologies to enhance the combustion process to such a high degree 

that it optimizes total engine performance while offering a highly effective 

emissions reduction solution. Because ACERT Technology is primarily 

for combustion, there is no external plumbing to clutter cramped engine 

rooms. And when you specify an engine, components are included 

only as needed, so you get a solution optimized for your application. In 

applications where stringent emissions standards are in force, Caterpillar 

engines with ACERT Technology deliver excellent performance, 

efficiency, and durability.

eNGINe cONtrOL AND 

mONItOrING sYstems 

For optimum performance and reliability, these exclusive engine control and 

monitoring systems are specifically designed for Caterpillar electronic marine 

propulsion engines. 

mini marine power Display (mpD) 

The Mini MPD is a compact, selfcontained 

engine monitoring and display 

system that provides the operator with 

engine and transmission information. The 

screen layouts can be easily configured 

to suit individual format preferences. In 

the event of an engine or transmission 

problem, an audible alarm alerts the 

operator and a text window with 

diagnostic information appears on the screen. The high-resolution transflective 

screen improves readability as ambient light conditions change. 

color marine power Display (mpD) 

The Color MPD combines all of the 

functionality and simplicity of the 

MPD with the ability to monitor two 

engines on a single display. Now, 

customizing the individual screen layout 

for up to three operators can be done 

directly from the display unit. Other 

enhancements include a significantly 

brighter screen display with adjustable intensity and twice the resolution to 

sharpen the streaming video being displayed from up to four camera inputs. 

marine Analog power Display (mApD) 

MAPD is an innovative system of electronically 

controlled analog gauges that monitor 

engine operation, offering accuracy 

and dependability with visual 

simplicity. Two sizes of gauges are 

available with choices of gauge face 

colors and bezel finishes. All gauges are LED backlighted and automatically 

calibrated. Up to 12 individual gauges or the convenient MAPD panel with up to 

seven gauges can be easily installed. 

multi-station control system (mscs) 

MSCS provides engine and transmission 

control for single or dual engine 

applications with up to eight control 

stations installed throughout the vessel. 

Control of the engine and transmission can 

be easily transferred from one station to 

another. A fully redundant backup system 

is included to ensure propulsion system 

operation in the event of a failure to the 

primary control system. In addition to the eight primary control stations, eight 

backup stations per vessel can also be installed. Transmission shift logic contains 

anti-stall strategy to prevent stalling the engine during quick shifting maneuvers. 

Several control head options are available for convenience and to coordinate 

with the vessel’s interior design.
