Engines IV: Yanmar V Cummins Marine Engines

As some of you may have realized we used to own the Grampstr's Endeavour a 38ft TrawlerCat, which was a beautiful trawler and in the future we will discuss our transition to the Grampstr's Pride, a 48ft TrawlerCat, but for now we are going to discuss one big difference -the engines. 


The Grampstr's Endeavour had two Yanmar Diesel engines.  Whereas, the Grampstr's Pride  has two tier 3 Cummins QSB 6.7ltr Turbo marine Diesel engines.  So the question you may be wondering is why the change in engines?

Lets first discuss the reasons why we did not go with another type of engine. It was not because there were issues with the Yanmar Diesel engines.  Yanmar has a great Marine reputation and has an excellent product.  It was also not because they did not have an engine that would propel the larger boat.  Yanmar has an excellent series of engines for most size watercraft.

The reason we went with the Cummins engines over the Yanmar was fuel efficiency.  After lots of research it turned out that Cummins Tier 3 engine was going to deliver a lot more efficiency and power for the size and type of trawler we were building.  After lots of discussion with Endeavour it was decided that this would be a good way to go.

As we have discussed there are a lot of things that go into choosing an engine.  If you have any questions on why we choose the engine we did please reach out to us.

We hope you will charter with us soon!
