100% correct ,
The ecu does not realize the engine has died because all the other sensors are providing a input to the ecu,except the crank and cam sensor (because the engine is not turning ) so it will trigger a false code.
another way to trigger a false crank sensor code as well as a knock sensor code(which I know we are not dealing with) is EMI ,depending on how the wiring harness is routed especially if its close to any ignition wiring you can be picking up Electromagnetic interference,

also guys i have to agree with bup, if youre using auto zone parts instead of mer cruiser you're just asking for trouble,just recently i tried and iac made by sierra which a marine application and it sucked,idle was too high,so high the cam wouldn't even chop and idle speed was higher so i went back to quicksilver and idle is back to how it should be,using aftermarket autoparts might give you a new set of issues if you ask me
