We are considering an upgrade of our 2003 360 Sundancer with 8.1s Mercs to something larger. The current idea is we are considering a 460 Sundancer if we can find just the right one for us. My question is about diesel engines. What is an ideal size/horsepower for a 460? Do I want cats or Cummins? What should I know about hours, maintenance, configuration etc? I’m just hoping to not end up with an under powered boat or a maintenance nightmare. I have always been a gas guy so I know very little about diesel. Any help is appreciated.
