Water tube for yamaha f15

[sveinis1000]

I have this Yamaha F15AE long version four stroke from year 2000. I bought a new watertube for it since the old cobber tube was just like sand. These engines are either short or long, I guess I´ve installed a wrong tube this time, too short...but how can I distinguish long from short models on your parts diagram? (yes I know you don´t sell european models, but all the other parts were 100%) Best regards, Svein

The "L" in the model number is for long shaft(20 inch shaft length) and the "S" is for short shaft(15 inch),
F15ML is long shaft, F15MS is short shaft.
