Hi,

What kind of lower unit oil should I buy for Chrysler 105HP engine?


Thank you

Quicksilver or whatever brand you prefer 80W-90 marine grade lower unit oil.

I use Wally Worlds 80/90 gear oil.
My twin 88/85's. Both leak a bit of water around the bottom seal/plug.
No matter what I try it still leaks.
So I change the oil a lot when I use the boat.

Any gear oil is ok.
You can spend the big bucks and get oil from Mercury or Yamaha.
But I only use it if a customer requests it. ​
