If something works, and it works well, why change it?
But it doesn't work well. It's inefficient, too heavy, barely generates enough power to get out of its own way, and is way*too maintenance-intense by my standards.
I don't mind old stuff if the objective is to restore a steam engine or an Austin Healey 3000 or keep an old Land*Rover running*or whatever.* They're just hobbies and aren't expected to be reliable or have good performance or be efficient.* They're fun to screw around with and if they run good every now and then, hey, that's a nice bonus.* Working on these things is at least half the fun of having them.
I do not have the same tolerance for an inefficient, outdated design when it comes to the engines in our boat.
One of Boeing's most famous engineers, Ed Wells, the "father of the B-17" once told me in explaining why he urged Boeing to get into jets that "Life's too short to be spent working on propellers."* He didn't say propellers didn't work, he said they were no longer worth messing with.* That pretty much sums up my attitude toward Lehmans and other old marine engines of the same era.
I don't think there's much point in continuing this debate because I'm never going to consider the FL120 or FL135 as anything but ancient, inefficient engines with little more than historical value.
