Caterpillar Marine Engines – Comprehensive Guide for Buyers (Part I)


Caterpillar Marine Engine

Most vessel owners rely on Caterpillar marine engines for high-end functionality, performance, durability, fuel efficiency, and low emissions. Caterpillar [aka Cat] was initially founded in 1925 as a tractor manufacturing company by Benjamin Holt and C.L. Best. Today it is one of the leading providers of construction and mining equipment, diesel engines, natural gas engines, diesel-electric locomotives, and industrial gas turbines across 192 countries worldwide.

While Cat engines is an obvious choice for all types of vessels, finding the right model may seem intimidating. Now it is possible to do it with ease from your own place. In this guide, we give you all the information to help you choose compatible Cat marine engine for your vessel.

Know Your Watercraft

Before you even look out for marine engines, it is vital to know the vessel specifications. The boat size, operational needs, weight are determining factors to consider when choosing the engine.

For instance, C18 Marine Diesel Engine featuring 4-stroke mechanism and running on 6 cylinders gives an output of 1,015 mhp to 1,150 mhp. This works fine for sports fishing boats.
