Dave, when I got into RC boats in the early 90s all the mags praised the OPS engines, I had 2 K&B .45 outboards. I bought an OPS 45 inboard, it was fast for a run. real fast, for that one short run. the setscrew for the Disk was not torqued down at all. I was lucky, all I need to buy was a new Disk and setscrew.
