Yes it is. Just unplug the oil line where the clear plastic “Sight glass” is which is just before the oil side of the pump and plug that port then route your pre-mix into the fuel side of the pump and you’ll be all set. If your controls alarm or give any issues then find the harness that connects the VRO pump to the main wire harness under the hood and disconnect it, then wa-la, go run your boat with pre-mix and enjoy with the Corona in hand fishing!

Exactly! That is the beauty of this system, easy to disable. No need to remove the VRO pump and replace it with conventional fuel pump, it works fine as just a fuel pump. And yes, your engine does have the no oil alarm, follow the harness back to the plug connector and simply unplug it. The low oil alarm leads for the oil tank will have to be disconnected also when you remove the tank…
The one thing I like to stress is that your engine cover calls out VRO injection so be very careful when refueling. It would be an understandle, yet fatal error if someone/dock boy just added straight fuel to your tank "assuming" the engine is oil injected….
