Re: 1978 70HP evinrude throttle
I recommend Amsoil synthetic red grease. Because this arm pivot tends to build wear particles and stick, I use only the highest quality grease. Restoring the older motors has been a passion for me going on 55 years now and high quality grease is so very important. Grease can "chalk up" over time, and cause troubles. I'll see if I have a photo of this part here on my phone. Take care and tell your friends about the forum. We have techs here, many retired status, with thousands and thousands of combined years of professional experience, ready to help those who simply ask. Parts also are right here, just a few "clicks" away.....and with a very reasonable price.
