Yes you are right which is why in an earlier post I suggested a relay with a timed on period or perhaps utilise the oil pressure alarm sensor to deactivate the stop sequence once the engine has stopped .
Volvo D1-13 and wiring in an engine immobilser.

But that will allow the engine to start once the time out as passed or the oil pressure has dropped.
The only way to stop the engine being started by using the stop solenoid is to hold the stop solenoid in all the time.
Best way is to use the in gear start interlock by keeping the interlock open circuit with the immobiliser relay.

But if the unit does not activate until it detects that the boat moved ( and I am not sure if it does that automatically or only when instructed to do so via a text message) the engine will already have been started . Opening the in gear start inhibit interlock is not going to achieve anything worthwhile.
Look at this video https://www.youtube.com/watch?v=COaRqMPAP_I and some of the others that follow and decide whether or not you'd fit it to your boat , or your car or simply donate it to the nearest skip.

Isn't the idea of an immobiliser is that when you leave your boat you set the immobiliser so that it prevents the possibility of starting the engine in the first place as well as other things like setting off an horn and flashing lights.
That's what a car immobiliser does or have I got it wrong
The GPS cutoff is am additional feature or have I got it wrong again

On a simple base engine like that, how about drilling a hole in the bell housing and inserting a bolt to jam the flywheel? OK not the question asked, but something that would be difficult to find and possibly more effective?

In the demo in the video it activates when he sends a text message to it, after being alerted by a text message that the boat has moved. It may be possible to program it to do it automatically when the boat has moved outside a certain area ... not sure.
Other than that it does not immobilise the engine AFAICS which is why I said right at the beginning the sensible approach is to operate some hidden/ secret immobilizing device before leaving the boat that will prevent the engine being started but the OP has bought this unsuitable bit of eBay junk and is determined to use the immobilising feature.

Talk about a sledgehammer to crack a nut!
A U-bolt:

Mount it to the cockpit floor so that you don't catch your knuckles in the unlikely event of needing FULL reverse.
Upon leaving the boat engage full reverse gear and lock the frickin' handle in the down position using wire, chain, padlock, whatever.
You could then even use the U bolt as a, oh I don't know, mount for your safety harness??
From memory my boats couldn't even be started in gear so why not use the boats existing system?
