The "Premium" oil is for motors under 75 hp. The oil for larger motors is "High Performance" oil. You should not mix the two types

Both should have flat nylon washers. They can sometimes stay in the hole, sometimes come out with the screw. Be sure to remove the old ones and fit new ones. here

The first screw you removed in the video the Philips headed one is not the drain screw..It's the one that holds the pinion shaft bearing in position as Racerone says. It should have an O ring seal on it! Fit a new one

Your pump should fit the lower hole to refill.

The drain screw is lower down, tucked in under the bulge in the gear case, and is a slotted screw like the top one..# 53 in your diagram

Johnson 90 hp - lower unit oil change - do i need washer for either screws? Today, I decided to change the lower unit oil for my Johnson 90 hp V4 outboard. So, I removed both the bottom and top screws to drain the old oil but I didn't find any washer in either screws. Is this correct? Looks to me from the picture below, Top screw (#45) has a washer part #46, however bottom screw (part #53) does not seem to have washer. If there is, the part list is not showing the washer part # separately. SO, I plan to buy a washer for the top screw only. OEM # 0311598 - Washer here
