I have a complete Mercruiser 140 for sale. $3500 for everything. That is complete with the engine, transom mount and lower unit plus prop. I checked compression which is all good (4 cyll) The unit seems like it was almost unused- no corrosion anywhere. Don't know the whole story. I can set up to run in the shop. Wiring to instruments was cut so do not have instrument package. Send message for photos and phone #'s. Located in Massachusetts- could deliver to USA east. Cheers/ Bob W.
