I agree that you should save your money and troubleshoot first. Many OMC engines also have ignition fuses. You should remove the hood and check any fuses that you see wired to the engine. Keep in mind that if it is a blown fuse, it means that there is a short somewhere.
I ran into the same situation once with a 40 horse Johnson. Two of the wires on the tach were crossed. It blew the fuse under the hood. Everything else worked.
Another time a short at the fuse box blew a fuse on my friend's boat. The fuse was right at the battery switch. In that case the entire boat lost power.
A third time a neighbor did the same as you; he shut down to fish and then had zero power to the starter. In his situation it was nothing more than a dirty battery terminal. Everything else was able to draw power but for some reason the engine was dead without the good connection at the terminals.
I'm a strong believer that when you go from power to zero power in a matter of minutes that it is nothing more than a blown fuse.
