Vehicle Information
Yamaha Terrapro 350 ATV (1988-1992)
The Yamaha Terrapro 350, a distinctive utility ATV, was primarily manufactured in 1987 and 1988. It stood out for its innovative Power Take-Off (PTO) system, allowing it to power various implements. Equipped with a 348cc or 349cc single-cylinder, 4-stroke, air-cooled engine, it delivered 14.5 horsepower, with 10 horsepower dedicated to the PTO. While your search covers 1988-1992, available information indicates that the Terrapro 350 was produced only in 1987 and 1988, with these two model years being identical. The Terrapro 350 (model code YFP350U) was offered as a single utility ATV model. There were no distinct "trims" or mid-cycle generation changes within its production run. Instead, Yamaha provided a range of specialized attachments, such as 48-inch finish mowers, 42-inch rough-cut mowers, and sprayer systems (50 or 100 gallons with 15 or 24-foot booms), all designed to leverage its unique PTO capability. The 1987 and 1988 models were identical. Q: How do I ensure I select the correct parts for my Yamaha Terrapro 350?
A: Please use the year and model selector at the top of the page to confirm compatibility for your specific ATV.
Maintenance
| Component | Interval | Details |
| Engine Oil and Oil Filter | Every 800 km, 50 hours, or once per season, whichever comes first | Check oil level every 10 hours. |
| Belt (CVT) | Inspect every 100 hours | Replace at first sign of damage. Keep CVT case and clutches clean. |
| Spark Plug | Inspect every 100 hours | Replace if corrosion is present. Condition indicates engine health. |
| Air Filter | Inspect every 25-50 hours (normal conditions) | Inspect after every ride in dusty/muddy conditions. Replace as needed, immediately if soaked. A dirty filter restricts airflow. |
| Coolant | Replace every 2 years or 200 hours | Check level regularly. Old coolant loses protective properties. |
