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 .
