Due to a recent post on this forum regarding a
fuel problem on a 50hp
Perkins, the question came up regarding
safety shutdowns controlling the shutdown solenoid and whether the solenoid would be Normally Open and require
power to close or be Normally closed and require
power to open.
Also wondering what the typical
installation for any
safety shutdowns would be (if any) as I am not aware of any
boat that has such devices installed. I would have thought that the last thing you would want is for your
engine to quit at the worst possible time such as maneuvering in a marina or other confined area as a result of a faulty temp or
oil pressure switch. Any
boat that I have ever seen will have warning devices installed but no capability to shut down the
engine automatically. On all the boats that I have operated the engine will run once started even with the power shut off as the shutdown solenoid requires power to close off the
fuel.
Just curious
