1987 Skeeter Strada F120 throttle control help!!

So I got a new to me boat a Skeeter Strada F120. I need to replace the throttle control handle. It is cracked. Any ideas on where to get one? Can I replace just the handle or do I have to replace the whole box and everything in it?

You SHOULD be able to locate a handle from a shop somewhere. No you SHOULDNT have to buy an entire control box.
Evinrude,Yamaha, Mercury??? What brand motor do you have?

I have a Johnson GT150 motor. The handle for sure need to be replaced. And the fast idle lever

If its more than just the shifter handle you may as well go ahead & replace the entire box. Should be able to find a complete used one for $125-150.
