propeller not engaged

I've recently inherited a 1996 evinrude 48 and have successfully managed to hit a submerged object causing a little damage to the prop, however, this is no longer operational because the gear drive is toast. My question is; is this subject covered well in the manual? Thanks for any info.
 
Some might argue.----I believe the gears in these motors are not big / sturdy enuff.-----It would be covered in a factory manual.----New gears and bearing are big $ items.---Plus shimming tool is required.----Best to look for another motor.

Thanks for the heads up, I'll keep my eyes open.
 
Okay, disassembly in progress and forward, reverse gears are in bad shape as is the shift dog. complete rebuild is in order. Is this worth while? this is a 1996 motor and I don't want to throw money at something if it's not worth it. Your thoughts?
 
That would be your call do you feel confident in doing the work? If the engine is otherwise in good shape by all means. Do a compression test and get back with the numbers?
 
Okay, everything is disassembled except the drive shaft and inner gear. I've received the SELOC repair manual but it only covers removal of the seals in the lower unit, not the entire gear assembly. This is manual 18-01312. Did I buy the wrong book?

You need to remove the pinion put a wrench on the nut and I use a pipe wrench on the shaft. There is a special tool that makes it nice to get the proper torque on the nut when putting back together once again I just go by feel with the pipe wrench. Lay on its side so no metal shaving get into the bearing. Did you note the shims under the upper bearing housing. Those shims are very important for gear lash it can be easy to drop or damage the shims.
 
Thanks,
No metal shavings per say, however, the shift dog is destroyed, and, the forward and reverse gears have obvious damage, so, I suppose that translates into metal shavings. I'm working blind because the manual does not seem to cover disassembly of this area. I will remove the nut and see if I can get the drive shaft housing out as well. I don't have a puller for this, might have to engineer something.
Do you happen to know if there is a manual that does cover this motor better?
 
A factory manual ( as per post # 2 ) is what covers all the details / tools required to do this fine work.----A shop would use a special splined socket to turn the driveshaft.----Other tools may damage precision parts.

Maybe I'm not seeing post #2. Do you know the particular manual? I ordered the one I mentioned but it does not deal with this work in any depth at all.
 
The best is a oem service manual a clymer might get you there as far as specs but a factory service manual will go into specifics. In general the bearings and gears are precision ground the big one is getting proper gearlash. Too close and you will cook the new gears in no time. Just take your time I assemble a gearbox several times without the seals until sure it is good then do the final assy and do a pressure/vac test!

Thanks for your time. I've done all i can without the proper repair manual, so, will hold the remaining work till then. Understood on the gear lash, similar to transmissions, etc.. I'm having particular trouble removing driveshaft bearing housing from the gear case. My puller is actually deforming the slot which tells me the pressure is decent but no effect. I've been able to rotate the piece slightly with a punch tapping back, and forth, however it still will not pull out with my methods. I know someone has accomplished this so I'll keep researching.
Good advice on the assembly routine, thanks again.
 
Power steering fluid and heat. Be careful if you use map gas aluminum has no memory just heat it until the power steering fluid bubbles.
