Author	Topic:   What Mercury Outboard Lower Units will Fit?
WhalerGoFar	posted 04-18-2005 07:59 PM ET (US)         I have a 1994 200hp 2.5 Liter with a crack in the hub (where the prop is) caused by salt build up. The crack is approching 4 to 5 inches long and I am in the market for a new (used) lower unit core. Does anyone know what year and model Mercury's Lower Units will fit this engine. Is there a reference sheet online or other resource you could point me toward. Mike Naples, Fl.

I think that if Mercury is anything like Evinrude, they used the same hull for several years and only played with the components inside to obtain a different gear ratio. I could be wrong....it won't be the first time...or the last. Mike

When ground down and painted, the repair is invisible and will probably last the life of the motor if done by a competent welder who has lots of experience with aluminum welding. BillS
