Speed run with new Volvo 6.0 in Boat Talk Posted July 2, 2013 I was at an in water boat show a couple week ends ago, looking at the new Chaps. I asked the salesman about the new Volvo 6.0 380 and he had good things to say about it. The only negative he had was that he thought it was a louder motor because of the higher RPMs it runs at. Have you all noticed an increase in decibels at cruising speeds over the other small or large blocks?Coming from a VP 5.7Gxi in my 2004 Four Winns 230, I haven't noticed any increase in loudness. I would guess that the 6.0 is quieter than the 5.7. You certainly notice the higher RPMs though!
