85hp Yam impeller and lower unit oil change..tips?

[HammondTiger]

Pulled the boat out of the water and I am changing OEM # 692-W0078-A0-00 water pump repair kit. I am also going to change the lu oil while I have it out. Are ther any other areas that I need to give a little attention to before I put it back? I am going to change the plugs as well. Thanks for any advice!

Get the LU pressure/vacuum checked while the LU is off if you have any concerns that water is entering the LU.

pull the prop and check for fishing line if its used in fishing areas and if there is some, you may need to change the prop shaft seals . If its leaking

Normally if the seals under the pump and shift shaft o-ring and seal is leaking you will know when the lube is changed
