Joe G: do you have a recommended schedule for changing the oil in the lower unit? Also, I thought you needed a special pump / attachment to pump in the new gear oil. After the 20-hr. service, my manual says I don't need to replace (but should still check) the lower unit oil until 200 hours. Whats your experience? -Eric
I have had a 1993 15 HP Johnson for the past few years. I just make sure I change the lower unit oil before there is a frost. I tell the guy at West Marine what type motor and he gave me the lube and pump for it. Very easy to do
Likewise Joe. I think I'll look into getting what I need to change the oil in the lower unit this year. I was going to check it, but changing it can't hurt.
