It's always good to see what manufactures that really know what they are doing recommend.

Yanmar manufacture and convert diesel engines (some from toyota base engines) for marine use. These typical run at high loads and outputs for extended periods.

Have a read of page 14 that covers break in for the BY3 series of engines

This recommends 60~70% of load for the first 10 hours (1000 klm equivalent) of operation with the first 50hrs being critical and to avoid extended periods of idling and light loads.

Enjoy the read!
