thanks for replying. the seals behind the prop that keep water out of the lower end. i can get the prop off but there is a ring that won't turn or anything?

Re: I have water in my out drive????

i've no experience replacing those seals. but i do know your gonna need a least 1 specialty tool to remove the nut to go after the seals. a bearing carrier retainer wrench... http://www.iboats.com/Bearing_Carri...0925027--**********.762022148--view_id.271217
by looking at the service manual ya need a puller to remove the carrier too. i believe this is where the seals are, in the bearing carrier..... go get yer service manual. it explains exactly what ya need to be doing for replaceing the seals. and there may be more to it than that as there's other inspections that are done after the carrier is removed...

here's another place ya can get some ideas and some tools to do the deed... http://www.mercstuff.com/bearingcarrierremoval.htm

the oem service manual has the exact method of servicing. so i'd take anything else with a grain of salt.... imho.....

Great thank you that was just what i was looking for. I have a dumb question if you are out on the water and the seals go and water gets into your lower end what is going to happen?

Re: I have water in my out drive????

i ain't the guy to answer yer question man. maybe the mods will move this over to the eng. forum for you. you'd have many more gurus reading this thread there. i'm just a end user like you... but my initial guess would be that water don't lub gears. and gears like lub. + water causes metal to rust. rust and gears in mesh and brgs. don't like rust. + i'd think the rust would cause the seals to go out as the metal surface would no longer be smooth, but rusty and rough. rough metal and seals i don't think go together.... you can test your drive for it being sealed too. a drive pressure test. ya empty the lub and then give it about 15psi of pressure and see if the air leaks out. it should hold this pressure forever......
