The Yanmar dealer here in Mex. is apparently on vacation
till next year. Yanmar is quite territorial so its hard to get much out of distant dealers so it seems. Given the designs to replace 4JH with 4JH it would seem logical that the block and flywheel would take the brackets from the previous engine. Being IP , not Yanmar, one wonders if there could be some interference
, particularly in the front. To fit prop shaft position and the eng. compartment as well, a KM35P gearbox
would seem to be in order and that looks like moving the attaching to bed bolts aft. A need to fiberglass
in metal for the female threads perhaps. How to do that? And, yes, you have to be careful who you ask about what.... Thanks for the reply.
