We have a 2003 Tiara with twin Cummins under contract. How is the engine noise? Is it possible to have a conversation when underway?

I have a 36 Sovran with Cummins. The noise is less than my previous 40 Searay with gas engines. It is very easy to carry on a conversation at the helm with others on the boat.

I have twin Cummins 660s and love them. Lots of torque for parking and way more efficient than my old gas engines on my 35 Open.

I agree, the noise at cruise (2100rpm/23 knts) is not bad on my 38 Open w/Cummins 6CTA diesels...
