Could the "U" in model number possible be a "V"? The 1997 is a 3 cylinder motor.

25 twin
Yamaha made a 25 two stroke in a twin as well as a triple - I believe the twin is best as I have tried both engines on the exact same boat. The twin was slightly faster (on gps) and you can still lift the thing which is a killer doing with the triple. I owned it for 15 years - a nice one with electric start and oil injection. The only thinge I ever needed to do was to change the impeller every 6-7 years and plugs every three years (never fouled one) it was just for preventive maintenance. This thing never failed to start even when I would go down to my boathouse and jump up and down in the boat to break the boat free from the ice at -15C and had to wiggle the motor back and forth to break it free from the ice so I could steer it. Used B6HS plugs in the winter. Hey !!!! we're Canadian!! Too bad they are all gone now - Bob
