steering control/ throttle&shift controls

[bdu27530]

I have a 96 Mercury 25 hp outboard, tiller control with electric start. I want to install a steering wheel plus throttle and shift controls and remove the tiller handle. I need info on what parts(ie part numbers) that I will need to do this conversion. Thanks The model # of the motor is 1-025301sd and serial # is OG296759
