Get a voltmeter with a max/min function. put it on the battery, crank the motor. If the battery stays up at 11V or more, there is probably a problem with the wiring. The motor is not drawing the current it should. If the volts are dragged down to say 8 V, then I'd guess the engine is stiff to turn, or the starter is shot.

Hand Cranking a Yanmar 3GM30F? | SailNet Community

Does anyone have any experience hand cranking a Yanmar 3GM30F? I could weld up a crank from an old socket.
