Lower unit oil change

[RW632]

My last outboard had an upper and lower plug that I pumped oil in the bottom till it came out the top. My current outboard has what appears to be two plugs that are side by side. What's the trick here? I am sure this is simple to most but I have never had one like this. I just purchased the boat and had it in the shop to perform carb. rebuild but told them I would change the lower unit oil myself (trying to save on that $92.00 per hour rate) then I go to change the oil and it does not look like my old outboard.

Re: Lower unit oil change

Some motors have a fill/vent set up.
You drain from the bottom.Then fill from the fill till it comes out the vent.I then do it the other way.In the vent till it comes out the fill.Then once more into the fill.Jerry
