Well.......Now that I paid a diesel mechanic to give me a $6000+
estimate to rebuild my M4-30, I have a bunch of boxes of parts
I am looking at kubota tractor engine short blocks that I can bolt all the
marine parts to. The M4-30 4-cylinder uses the kubota Y-850 block.
From what I can dig up the M-25XP 3-cylinder is the kubota D-950 block.
My research leads me to believe that the more recent D-905 3-cylinder
block will accept my bell housing, front gear case and the REST.
Kubota short blocks are remanufactured regularly in Tractor Country.
Have found several rebuilders with short blocks IN STOCK
Just have to verify the bolt-up. Experience with this would be GREAT !
A gear-jammin friend of mine reminded me that my M4-30 is no longer a
marine engine.....just a box of TRACTOR PARTS
Also looking for the Parts Diagram or Service Manual pdf on the
Hurth HBW-50 Transmission so I can put that back together !
Thank you to all you old tractor riders /) /)
