Re: Rear oil seal
The special wrench is part number 177099-09010. It's not cheap. Since I posted, I remembered that the O-ring was missing when the guy pulled the seal and he didn't see the purpose for it so he didn't put one back in. It looks like it's intended to keep fluid from migrating past the seal on the outside where it fits against the seal housing. I worried about his not having put it in, but I haven't have any leakage, but if you can get it in, all the better.
The seal came right out. It's not pressed in. The guy had a pick and a paint can opener for removal tools. He showed me how either one would have worked. The hard part is working in the space between the trans coupler and shaft coupler. Much depends on how far you can slide the shaft aft to make space. You will have to pretzel down so you can see to work or use a mirror (neither me nor my guy had to use one). Clean the shaft if there's any crud on it before sliding it aft to keep from tearing up the packing in the packing gland.
Use a pipe wrench on the trans coupler braced against the hull to hold the coupler so you can wrench on the nut. The nut is normal right hand thread (counter-clockwise to come off), unlike some boat transmissions.
The nut should be caulked after replacing it to keep it from loosening when in reverse. The caulking doesn't keep it from loosening when you get on it to remove it with the wrench, though. The dimple isn't that deep.
Forgive me if I'm telling you stuff you already know. Just trying to cover what I remember. Good luck. Let me know if you need anything else.
