Going to change the stern drive lube, but all directions say to remove vent screw and remove lower screw and let drain. I have a 1995 Mariah Talari 210 with the 5.0 LX motor, it does not have a lower screw. At least I am unable to locate one. I have looked all over, both sides and even removed the prop and checked there. It has the remote reservoir, but no drain screw. Am I missing something or can someone tell me how I am supposed to go about changing this. I don't want to screw it up, thanks for any and all replies.

What brand and model of stern drive do you have?

[Dogloop]

Sorry its a Mercruiser Alpha One.

Thanks!

It should be on the Starboard side of the lower unit, just above the skeg, on the bottom side of the bullet.

Starboard?
Mine is on the Port side on the bottom side of the "bullet".

[Dogloop]

Yeah mine was on the port side as well, but I hadn't look that far down. It's really on the bottom of the bullet, I had thought it would be on the side, but you actually have to look on the bottom. I looked all over that that thing, but never looked on the bottom until this post.

On mine it's on the starboard, glad you found it though, you also have a drain on the upper unit.
Pump new gear oil in from the bottom drain until it comes out the top drain, this will push out any air.
Put the plug back in the top drain then continue pumping til lube is visible at the reservoir.
Put the bottom drain back, wipe up the stinky mess and top off at the reservoir.
