I'd be very careful. Just bought a 1990 12m from Florida and it ran fine at 1300hrs. I'm now $20,000 into cylinder wall overhauls etc due to water intrusion from somewhere{ turbos above the shaft logs?] You're the first on our site to be made aware of this so I don't know if others have gone thru the same pain. GET AN ENGINE SURVEY NO MATTER WHAT !!!

Hey thanks for the insight. I will be sure to get an engine survey. These DD were just rebuilt apparently, 10 hrs on the DD 671. So will see how the survey goes, getting it done in a few weeks. I appreciate your reply.
How do you like your 12 meter, anything I should know about them. ,
boatdiesel.com is a good source

We have two DD 671 TI in our 11 meter express. We had them majored and they are great engines. I would get a oil sample and have a mechanic check the engines. He can look at the cylinder walls and see if they are rusted. We knew the condition of the boat engines when we bought the boat.

I have a 40' 1982 trojan tri cabin with twin 671s total hours are just over 2000. Mine are naturally aspired and rated at 230 hp. These are old fathful, push the button and they go! At 1600 rpm consumption is bearable at 55 Liters per hour total at 9.5 knots. They will run all day over that but the consumption goes up faster than the speed. Great boat!!
