Using the diagram found on this forum for a similar model I wired up a new ignition switch. Not working, and this is a new motor boat combo to me, as I just bought the both of them 2 weeks ago.
M (raised) - kill circuit (black / yellow)
M (regular) - ground - (black)
A - accessory - (purple)
S - starter / solenoid - (white)
C - choke or primer solenoid - (purple/white)
B - batt - (red)
This boat is new to me and perhaps someone has seen a similar config as mine.
I have no white wire, but I do have a thicker yellow/red (assuming this to be starter/solenoid)
I also have a tan wire, but the black/yellow wire that "should" be for the kill circuit does kill the motor, but in both key positions. It was cut short by the previous owner.
The rest of the wires seem to match the above diagram.
