Johnson remote control question

[geedubcpa]

I have a 9.9 motor for my pontoon boat that I need to setup with controls - It does not have electric start, so the controls only need to do the forward and reverse and kill switch. My motor is a 1999.

What controls should I be looking for on Ebay or other places? Does it matter if it has the key switch even if I don't need it? Also can the kill switch be remote?

Thanks in advance for your ideas.
