Engine: Yamaha 115 Shopping experience: The rare parts I needed were in stock and way faster shipping than I expected. The illustrations that described the parts were very accurate. Repair difficulty: Medium Repair time: 30 to 60 mins Repair symptoms: 100 hour maintenance Hard to find water impeller and thermostat were installed. Repair went smooth.
