I am looking for a lower unit for a 1997 175hp Johnson Fast Strike. (Model# J175GLEU) According to Johnson it has a 2 piece drive shaft. I have taken the unit to a dealer here locally and they said that it needs completely rebuilt and that I can buy one already rebuilt cheaper than they can rebuild it buying the parts. The "best deal" they could find on a rebuilt one was $2800 plus shipping and tax. Johnson.com said a completely new one from them runs $2900. I would like to get out as reasonable as possible. All suggestions for purchase of used, rebuilt, or even rebuilding the existing one will be greatly appreciated. The housing is in good shape.
