" I'm trying to ID an olde
" I'm trying to ID an older OMC I/O. The model number is HUFM20D and appears to be a Buick V6 engine. Anyone know what year this is and what size the engine might be? Also, does anyone know what engine can be bolted up to replace a Buick 300 V8 (1967 I think) - this is also an OMC. Am trying to get one of them running, the V6 is stuck and the V8 is cracked on both outer water jackets. "
