I have been searching all over the US for a lower unit for a 1987 30hp
Yamaha model# 30SH.

It is a short shaft. I have found many long shafts but I have not been
able find a short shaft. Does anyone know where to get a USED one. A
new one cost more than the motor is worth.

If you know of a shop that carries used lower units or of a jet drive
shop that might have some lower units they took off, please let me
know.

Thanks
