Cat C-9 ACERT Has 575-hp - 09/30/2009
Owners' Reports
Capt. Rob Smith takes a look at Caterpillar’s workhorse diesel the C-9, which with the addition of ACERT is up to 575-hp.

Cat’s C-9 has a 510-hp output, but with the addition of the ACERT technology is boosted up to 575-hp. This makes her a competitive engine in the mid range of boats using diesel power. This 8.8 L, inline 6 engine is turbocharged and after cooled and weighs 2,086 lbs. (946 kg.). If you are buying a new boat with diesels in the 500 to 600-hp range you need to carefully consider your options, and Caterpillar is a good one. Watch Capt. Rob’s video of the Cat C-9 --
