'Power to run' means that if you have an electrical failure the engine will shut down. A faulty fuel control solenoid could shut you down, one lousy loose wire. Think about a rough sea or you get in the way of a much larger vessel or are travelling a current ridden or narrow passage. More than one boat came home after an electrical failure as long as the engine was running or could be started with an independent battery. Often as a backup with this setup people have rigged a mechanical means of closing the fuel valve.
Don't get me wrong as this is what I have, power to run.
'Power to stop' means once started the engine will continue to run regardless of whether the electrical system fails or not. On a boat this is usually an advantage.
If you truly have a runaway engine the fuel solenoid will not stop it anyway. Usually the fuel the engine has found has bypassed the controll, such as crankcase oil. The diesel control solenoid can do nothing. In a case like that the only way is an air shutoff which has to be rigged to operate before a situation like this occurs. Runaways are much less likely with the 4 cycle engines than with the 2 cycles.
