You might consider having a spare starter –they are inexpensive if not sold by Yanmar. Just put it in and if it works then send the old one out to be rebuilt. I believe it is either the isolated ground solenoid, the switch relay or the starter solenoid mounted on the solenoid.
A bit of Corrosion x would also help on the connections.
However I believe it is one of the relays or solenoid since it works when it is hot.
But all the possible solutions have been posted as far as I can see.

First thing to do is to check, clean, and tighten ALL connections between the battery and starter. A friend of mine who is a diesel mechanic says it the most common problem with a slow starting diesel.
