water pump kit/gear case seals

[cfh1177]

I have a 1988 20hp Envinrude, E20CRCCA. I’m going order a water pump kit but read in a manual online about replacing the gear case seals as well. Are they the same seals included in the water pump kit # 0393630 or do I also need to order a gear case seal kit # 0396351 ?

Thanks!

Would need to order seals or seal kit.
