1990 Johnson 175 GT SE SLE lower unit oil type

[OhioBassGuy]

Hello! First time poster here. I recently bought a 1990 Javelin 389 with a 175 GT SESLE engine. While reading through the manual i noticed it calls for "omc high-vis gearcase lube". I cant seem to find this anywhere (probably no longer made) or find any detailed information on it. I was wondering if anyone had any ideas on what gearcase oil I can/should use as an alternate? Its an older boat but was my uncles since new and was taken very good care of, so I would like to avoid making a rookie mistake and causing serious damage to the lower unit. Any help would be awesome!

Any good GL5 MARINE not automotive oil, I use Serria H-po oil..You can get it at Basspro or any boat store....
