You need to be sure to stop and start the gen with no load on it. Otherwise you risk burning out the voltage regulator.
If the Magnum inverter is the ONLY load, then you are all set since it will wait for the gen to start before it applies it's load, and drop the load as soon as it sees the gen falter, or before it commands a shutdown.
But on a boat there are typically other loads that do not go through the inverter like a water heater, other chargers, etc. Those loads will have to be manually turned on and off, or just left off when using the auto start. If you want to get fancy, you could automate switching of those other loads, but that's probably more complicated that you want.

It's not all that complicated. You have a couple of options. You can install a timed relay to the generator transfer switch .Some generators have this built in. Something like this is used in a lot of back up generators on land. Or, you can simply turn off the panels to the non-inverter powered loads whenever you are using the inverter and turn them on when using shore power or the genset.
Remember, the inverter loads should be on their own dedicated panel.
