starter wiring 1997 Bow Rider 175, 130 Mercruiser

[Boat Rookie]

ANY one, Help.
I really screwed up.
Sitting all fall and most of winter.
Cover leaking, Plug in. I drained all the water out. The starter wiring was all disintegrated at the connections.
I have replaced the starter. However, nothing I can find for a wiring diagram shows exactly the wires I have available to reconnect.

Also, need to know if anything else I need to check for damage. All looks pretty good except this.

Thanks for any help
