Yamaha lower unit drain screws

[climb29028]

Hi Everyone. I'm going to change the lower unit gear oil on my 60hp Yamaha four stroke motor and just wanted to know how tight I should tighten the screws (with new gaskets) on the upper and lower screws when I have the fresh gear oil in? Thanks.

service manual for the motor you are working on is a very good idea to have.
Hope someone with one for your motor will read your post and chime in.
The manual would save time also

Good and darn tight....but it's not a 24 inch breaker bar job.....just good and snug!...
