I have a Yanmar 1GM in my CD25D. On looking at the records, the head seems not to have been retorqued after installation in 1983. The engine runs fine - should I have this done next year or let well enough alone? Also, can anyone tell me how to wire an engine hour timer into the engine control unit?
Thanks for any advice.
