toon 2 year old merc what is needed for lower unit and oil change

[shorthairsrus]

I know what to do on my etec - torque specs/ where to hook up my laptop etc.

I have buddy though with a merc ---- 150 and its 2 years old

- - - Updated - - -

1. what is the torque specs on prop if any
2. lower unit - do we replace the seals - are they rubber- torque specs?
3. oil change -- if i remember the plug is under the prop -- just drain and fill ? Oil filter is it somewhere i can get at.

what else am i missing

oil plug is on side of motor and filter is right under the hood and easy to get to. I never messed with any of the other stuff so no help

When it comes to the lower unit, I always replace the seals on the plugs. It's only a few bucks a lower unit will cost you much more. Always dip the seals in some lube before tightening down the plugs. I've never torqued it, I just go to hand tight.
