420 SIB will weight less than a 380 RIB. Thus, smaller engine can be perfect, and you will save a lot in petrol. Beware large SIBs often need long shaft engine.
Nevertheless, 420 is too heavy to mount/dismount.
I would go for a 380 SIB (Bombard Aerotech/Honwave) and a 18HP Tohatsu 2 stroke if mounting/dismounting, provided you have a high pressure pump to inflate the floor to the proper pressure.
Also, a Zodiac Futura small enough would be a good option. And if what you demand is speed, go for a zapcat or similar.
But the best rule is:
First choose the engine then get the boat.
