I am in the process of purchasing and surveying a 1976 GB 36 Classic with twin JD 6404DF-02 engines with about 2500 hours each. From what I've been reading, these are dependable engines and assuming proper maintenance and care should provide dependable power. The only issue I've seen discussed is availability of parts, as the JD's were not widely used in later GB's. For anyone with these engines, have you been able to find the necessary maintenance parts (fuel and oil filters, impellers, hoses, etc.) either at the boat yard or through diesel supply companies? Thanks for sharing any experiences you may have had with these engines.
