[JonW25]

I have a 1965 evinrude 6hp. I was wondering if anyone knew what type of oil the lower unit uses in this year and hp.
Thanks for any help.

85-90 weight marine gear oil. Available anywhere (like wal mart)
Don't take out the philips head screw.

Don't forget to replace the crush washers on both the drain and vent screws.
