SportPort, no offense but I don't think you'll find anyone running a 480lb motor on a SeaCraft 18. Not sure of the year of your Suzuki but thats the approximate weight of recent DF 175s
A couple of questions:
Is your boat a SeaCraft 18?
What prop (specifically) are you running?
I would recommend going down in pitch at your prop guys expense and make sure the specific model of prop is designed for your set-up.
Clearly you need to drop in pitch, but my guess is that you also need a stern lifting prop to manage the weight of that motor. That means big blades with a low to moderate rake, little cupping and maybe even consider a 4 blade prop.
Good luck
