Gary, did you ever find a good solution for your controls?
My Teleflex is giving my trouble. The little button in the middle that keeps the engines from going into gear is stuck, so I can't get the engine in gear, or throttle up in neutral. It has locked the throttle control lever in one position. I had to disconnect the shifter cable from the inside this AM and bypass the neutral only start circuit to get her fired up just to charge my batts. And I normally like to charge my batts with the engine running in reverse, but can't do that today.
I was looking around for a manual on this unit, didn't find one yet, still looking. I assume most SLM BCC's in Elizabeth's vintage came with the same engine controls. Anyone else have a similar problem?
This is a pic of a newer one that looks sorta like mine with that center button:
