Hey guys this is probably a dumb question but i just want to make sure i get it right!! I have a 1998 150 Johnson Fast Strike and i need to change the lower unit oil and i was reasearching different types and i saw all these ratings ie. GL-5, and i think ATI and a lot of others, i was wondering what the right type of oil i needed to run in it?? any help would greatly be appreciated thanks.
