After all the Volvo, Cummins and old Lehman talk I did a bit of surfing ( very little ) and came up with an interesting possible replacement for the 120/135 Lehmans. Most of the guys with them don't seem to need much more than half power so a full power replacement would'nt make sense and some need a bit more power like perhaps a GB 36 w single eng. Many said they liked the simplicity of the Lehman. The engine I have in mind is a small IVECO. 99 and 148hp, 4 and 6 cyl versions of the same basic engine. CCW rotation, 274 and 409 cu in. Comp 17.5. Weight 992 and 1168 lbs. They are both naturally aspirated and to my knowlege no electronics. I don't see that they are in any way more complicated than a Lehman. They are rated for pleasurecraft use up to 90% power continously so the 99hp 4cyl should work very well for most but if one had a boat where the owner wanted to run his boat at full speed w the Lehman the 148hp IVECO should deliver.
