wanted yanmar 4LH STE 230HP

[COW]

During complete overhaul my engine block YANMAR 4LH STE has been found slightly cracked, need to replace it.
Anyone could tell me if other yanmar blocks are suitable for 4LH STE (i.e: 4LHA STE or 4LH DTE ?).
Anyone could tell me if any repair on the block could be made ?

Ready to study any proposal as need to be repaired or replaced urgently..(complete running engines welcome too!)

We discussed already by pm - i think all the 4 lh blocks are easily interchangable. My delta rib initially had an DTE block when it started its military life, which got changed to a bigger 230hp ste in 2008 when the boat came into private hands . I understood from dave crawford (the engineer in lymington who did the replacing) that it was quite an easy conversion at that time.

It is not entirely my field of expertise so please correct me if i'm wrong , but the differences in the 4lh engines are due to different intercooler, turbo size and fuelpump .

Good morning,

thank you. As expected there is no way to repair the crack on my engine block.
I need to find a 4LH STE block because on others LH models, the fittings and pipings are slightly different between models. Other way is to find a running 4LHA STE which i could put to replace the 4LH STE, the question is to know if overhaul dimensions and mounting brackets are identical !

All infos are welcome !
