Yamaha 8 HP Outboard Thermostat

  • by

We have a Yamaha 8 HP 2-stroke outboard for our dinghy (1999 model 8SMHX). I reported earlier about how to change its water pump impeller (here). We did that because the telltale wasn’t flowing water, and it still wasn’t after we serviced the water pump. So we took off the head cover to look at the thermostat.
