Upper lower unit shaft seal for QD-17

[Tech Tony]

I am resealing my qd-17 1956 10 hp lower unit and I have all the seals except for the upper shaft seal. The manual gives an old part number that dose not cross over and it is giving me a bad time trying to find it. I guess I could buy the kit for 40.00, but all I need Is that one seal. I'm sure there is a Sierra p/n that someone might know from resealing their qd-17..Help!! thanks

Lets not all answer at once ok?

I don't have the schematic in front of me to see which one fits the 56, but if the seal installs into the lower pump housing it is a Sierra 18-2022. If it installs directly into the gearcase it is an 19-2032.

Thank you RCO, I will check that and let you know what I find out.
