Boat ran fine on the way home. Cruised at about 3K rpm for 10-15 minutes then came down to an idle without issue to dock. No spit/sputter or rpm weirdness.
Considering it was hard to start, ran fire back home, now won't start, doesn't make me think ECM either, but cannot rule it out yet.
I'm more likely thinking part of the start lock-out circuit that allows the pump and injectors to power up. Most EFI systems lock-out on crank position, oil level, and coolant temp. Those are the 3 sensors I would go after first.

Coolant temp sensor fails high
Oil Level sensor fails low
Crank position just fails and doesn't give feedback.
