If you've been having problems, I can't see a reason to NOT have some test equipment.
Next time, disconnect the purple wire at the ignition switch. If it shuts off, you'll know the switch (or the way it's wired) is causing this. Are you absolutely sure the switch doesn't show continuity between the terminal used for the purple wire and battery all the time and only needs to be cranked to start it?
Turn the switch to OFF and measure voltage at the purple wire on the alternator. If you see voltage, reconnect it, disconnect the purple wire at the switch and measure voltage at the alternator again. If it still has voltage, something is wired wrong or you have a short. Make sure the two ends of the boat plug fit together without forcing them and that it didn't rotate when/if it was plugged in after the engine swap.
