I agree with you that the 4LH - 170 Yanmar is an excellent small lightweight Marine diesel. Tino and Adib Mastry sold warehouses full of them and many are still running strongly today. I think the Cat 3208-T in 320 Hp rating is a very good motor, but the 210 hp rated 3208's are still pushing around wooden Grand Banks. The Detroit Diesel 71 series in 3 and 6 cylinder in-line configurations is a very good design and has been around since WWII. The Stewart and Stevenson 671 made 450 HP but it's tough to find one that has 1500 hours on it and still runs. The 40 year old 210 HP 671's are still working every day in fishing boats tugs and crew boats. Of course their captains have gone deaf! After 15 years, Ford is still on a mission to show Internation Harvester how to make a high horsepower V-8 diesel for their trucks. The problem is they they really haven't come up with anything better that the 7.3 "Corn Binder" in about 230 hp rating.
It's had to make lots of horsepower in a small engine without creating alot of harmful heat. If you have a little more cubic inches and turn them easy they will last much longer. I just always notice the boat adds say "2002 32' Luhrs, fresh Yanmars......" and some say "1978 34 Hatteras, 265hp - 3208 Cats.....runs good".
