"1995 Yamaha 9.9HP High Thrust Long Shaft Outboard
Well its summer but the snowball keeps rolling around here. What started off as an impeller replacement has turned into a complete nightmare.
I started off by struggling to no end to get the gear case off and finally found the solution by heating the 4 bolts that hold the gear case and knocking out the corrosion enough for the lower unit to come free.
With the lower leg free, I then removed the four bolts holding the top of the water pump on and that came free without to much trouble. Of course the impeller was fine so I popped on a new gasket and tightened up the four bolts. Only on the last one did I tighten it just a little to much and I felt it weaken and snap.
So I drilled a hole in the bolt and tried to use a broken bolt extractor to remove it. Of course that broke in the broken bolt.
Thinking I may be able to get at the bolt if I remove the seal housing below the water pump, I began prying off the seal housing (as stated in the clymer manual)and it actually separated.
Now I have the seal housing free but the drive shaft is stopping it from sliding off.
So my question is, do I have to remove the drive shaft to get the seal housing off or is there another approach with the seals in the housing - my clymer manual doesnt say? If it turns out that the drive shaft has to be removed wich looks complicated and requires special tools, is this something I want to do or should I just lower my head in shame and take it to a dealer?
Thanks in advance for any help."
