    MY dad's new yanmar 3 cylinder, 24HP diesel he's installing in his
    boat has individual compression release levers. It has no means to
    hand crank the engine for manual start and the engine manual says use
    the fuel cut off to shut down the engine. So, what the heck are the compression releases for?
    Any clues appreciated.

    They would be used to help start the engine by hand. You would engage
    compression levers on all cylinders, then you can get the engine
    by hand, and then quickly dis-engage the compression release levers.

    To bleed the feeds to the injectors I release the compression, crank
    the engine while I loosen the nuts at the injectors until fuels drips
    and then close them.
