Rule 1 dont force it.
Can you rock the flywheel back and forth with the spanner to the same hard spot? Could be a number of things but sounds serious, something in the valve train?

Sounds like its dropped a valve... you might be able to see which one with the tappet cover off, not that it helps you much out there. CG member?

Sorry Vic. this doesn't sound good. A solid dead stop means a serious obstruction. Scenarios...... Valve head broken and fallen into cyclinder. Conrod has broken and is jamming against the bottom of bore. Crankshaft is broken. Cam must be OK if you saw all tappets working, so that's ruled out. A bolt has come out of Big end bearing and jammed.
You should find that in all scnearios, the engine will stop at same point. Mark the flywheel and buy hand, if you turn flywheel backwards, does it jam at ruffly same position. If yes, then any of the above are possible.
If not, then it could be a component in part of the engine that is geared down. Like the Fuel pump for example, may jam at fourth Revolution or some other random point.
No matter what, sorry but you are going to need a tow home, or sail it home if conditions are right for you.

Usually if it's mechanical you can hear the metalic clank as the crank hit the broken rod or whatever. If it's water, removing the injector and then turning it over will give you a shower....
There is nothing, absolutely nothing, half so much worth doing, as simply messing about in boats
