Merc 50hp would keep stalling out at idle. Doesn't make any sense, but this was the issue. Quickly replaced and its been working for a whole year now.

I had no idea why my engine was mad at me, but all of a sudden I got an alarm, and the engine wouldn't let me go much above an idle. Luckily, I wasn't that far away from my slip. I'd never had an issue like this, so it was a little alarming ($$$ going in my head)...After safely tying up, I started doing some research, and figured out that the most likely problem was my thermostat. My thermostat??!?? I always got a new one at the beginning of each season, and had never had an issue before. Well, apparently if you go through foul water, or lots of weeds, or stuff like that, that detritus can get clogged up in the thermostat, and cause the engine to overheat. It protected itself (lucky for me!!!), and so I searched around for a replacement.I came across this thermostat, and after changing it (a very easy job to do), my engine runs great again! Win!!!It was an easy fix, and this is a great replacement at an excellent price point. At $18.50, it's a great deal, and I plan on having at least one extra on board in case it ever happens again.Recommended!
