    Is the crank still assembled in the engine or is it out?

    It's going to be a little tricky as it's out of the boat. Bring the PTO piston to TDC and then lower it about 1 inch. Get a rope and install it into the PTO cylinder, leave a piece sticking out of the spark plug hole so you can remove it later. Rotate the crank by hand until it stops.
    Now the hard part, get your wrench, coupler removal tool or whatever you're going to use, have somebody hold the engine in place and break the coupler loose from the crankshaft.

    You should see the cheater bar I use when they are in the boat.
    What are you using on the coupler end, if it's the coupler tool you can use an impact and it'll come right off.
    You can also remove the entire crankshaft and send it to your rebuilder and they'll remove it when they rebuild or exchange the unit.

    You need to drop the rope into the cylinder and leave just a little tip sticking out, depending on the rope you use, you can get a foot or more into the cylinder.
    You want enough rope to stop the piston from rotating.
