Wow! Thanks, Guru, I was thinking of going to the Trawler Fest in BWI this Sept and taking the diesel class with Bob Smith of Lehman fame.
All Guru means is that you've sent more than x-number of posts to the forum.* It has nothing to do with whether or not any of them were worth anything.
I have not taken Bob Smith's class--- everything I need to know about our engines I either get from our diesel shop or by calling Bob or Brian Smith directly--- but I understand Bob's class is very good with regards to the old generation diesels like the Lehman.* So if you have the opportunity to take it I would do so as you'll learn a lot.
We've had this discussion before on the forum, but my dislike of Lehman engines, the FL120 in particular, does not stem from unreliability but from their ancient, almost prehistoric design and performance.* In a nutshell (and in my opinion*only) they are too heavy, too noisy, too inefficient, too maintenance-intense,*and too polluting.** And they are way too underpowered for their size and weight.
The FL120 is based on a 1950's Ford of England truck engine that was unsuccessful in trucks but was good (in its day) for industrial and agricutural applications.* Which is why it was popular for marine applications, too, at that time.* And at that time--- 1960s--- it was one of the better marine diesels around.* But its time has long since disappeared over the horizon.
If you find the perfect boat for you and it has one or two Ford Lehmans in it, by all means buy the boat if everything including the engine(s) surveys well.* But if you end up finding a great boat for you with Lehmans and a great boat for you with Cats, John Deeres, Cummins, Luggers, Volvos, MANs, etc, all else being equal I would recommend*that you*buy the boat without the Lehman(s).
