Lehman 275 hp Turbo's

I have a pair of 275 hp turbo Lehman's in my 46 ft. trawler.* I had to rebuild one after running a valve through the engine, so I quickly changed the valves on the other engine.* I have heard these 275 hp engines have this problem.* What is the way to avoid this problem from happening again?* Will running the engines under 1800 rpm's help or will I have other problems running them at lower rpm's most of the time?* These engine's have low hrs. 1,000 hrs.* on them Thanks in advance for any help out there.....Roger

RE: Lehman 275 hp Turbo's

Roger, as Marin would suggest, I would suggest as well. Bob Smith at American Diesel would probably be your best source for this sort of information. I know there are a lot of Lehman owners on here but I don't know if there are any folks on here with the boosted ones.
