I have a 1999 Yamaha 4 stroke 25hp. I'm in need of the lower unit drive shaft, the shift cam rod assembly, the 4 bolts that hold the lower unit to the leg, etc. Basically some lower unit parts, or a complete unit that might be broken (I have the gears and the gear case that are good). Short shaft only. I think '98 through '06 are basically the same. '07-newer are different and all 2 strokes are different.
