Marine Diesel Engines for Propulsion and Auxiliary Power

Debunking the Myth: Guascor Marine Engines Over 30 Years Old Are Far From Obsolete ⚓

In the marine industry, longevity and reliability are paramount. Yet, a persistent misconception continues to circulate among ship owners and operators: that Guascor marine propulsion and auxiliary engines produced over 30 years ago are obsolete, and that spare parts and overhaul components are no longer available. This belief has led many to consider dismantling perfectly functional engines and investing in costly replacements. The truth? This is a myth—and an expensive one at that.

Many people in the marine industry believe that Guascor marine propulsion and auxiliary engines manufactured over 30 years ago are obsolete, with no available spare or overhaul parts. This is a significant misconception. Our company can supply brand new parts for these classic engines with a short lead time, allowing them to be overhauled for another decade of reliable operation. Ship owners can avoid the costly and time-consuming process of dismantling their old engines and purchasing new, expensive replacements, which would be a major financial burden.
