After researching options, I went with the Cat C18 from Vaz Auto Solutions for my fishing boat repower. Couldn’t be happier with the decision. The engine’s reliability is top-notch – hasn’t missed a beat in rough seas. It’s quieter than my old powerplant too.

Just installed the Cat C18 I got from Vaz Auto Solutions in my work truck. This engine’s a beast! Plenty of power for hauling heavy loads up steep grades. The fuel efficiency is better than I expected for such a big motor.
