My boat came with an Evinrude TM. I like the TM just fine. It even has a light under the direction arrow for night fishing. Went on eBay to buy a spare prop, and they want 50 bucks for it. I've never paid anything close to that for a TM prop. I don't see the reasoning behind it. It doesn't even have a nut on the shaft, just a cotter pin through it.
