I’ve always wanted a Stevens myself, and finally found one for $10 bucks at a MAPS Chapter meet. I had to send it back to Stevens to be repaired. They completely went through it, and even installed a new meter face, along with new alligator clips on all the leads. This particular ST75 belonged to Kerry Marine [a local Evinrude Dealer] that was here in Camdenton Mo. It’s a fantastic machine for the old outboard enthusiast. I use mine on every motor I go through to get running. The ST75 runs on AC power as well as batteries for portability. If you need information or a manual, etc. give them a call. They were very friendly on the phone and good to deal with.
