- There is no filter to filter the 2 cycle oil.

- There usually is no water seperator unless one was added later.
Racor makes a nice unit. The actual filter element looks like an
automotive oil filter, but has a clear bowl with a drain on the bottom.
Be sure to get the filter specifically designed for outboatbord use. It
will have a 10 micron filter element.

- I never changed lower unit oil in a Merc. On an OMC they are located
just below and above the gearcase. It vents through the fill. Make sure
you use the right type of oil. Read about this as the condition of the
old oil will tell you alot about the condition of the gearcase.

Good luck with the new boat!!
