I also have 3208s, mine are rated at 210 horsepower each (naturals), and run at about 1900 RPMs with no problems. I like the engines and have owned the boat for over three (3) years with no problems to date with the engines. I know there has been a lot of discussion about under power but she had the 3208s when I bought her and I liked that fact. The PO had done a repower about 1990 and put them in then. I can do about 8 gallons per hour with just the engines and just a little less than 10 gallons per hour with the gen set running.
I do have an exhaust leak in the pipe going through the aft stateroom but that does not reflect on the engines. That will be fixed in a few weeks when I pull her to repaint the bottom, always some thing to do on them and never enough time or money to get it done.
