For a new to you engine with unknown maintenance history, change engine oil and lower unit oil (use manufacturer recommended grades), change spark plugs.

When you first use it run with fresh gasoline and bring the engine speed up slowly to check operation. Check throttle linkage and idle setting.

Test forward, neutral and reverse tied to the dock to make sure all linkages are good, then go for a short run to check operation under load.

If you don't know the history on filter or fuel, flush/clean/replace filter cartridge and drain fuel from tank, then use new fuel. Check for sediment/debris in the tank and tank fuel pick-up.
