Grab the propeller from the root of the blades and shake it; nothing should be loose there either. Then, look carefully: No oil should be leaking from anywhere close to the propeller. Now move the propeller with your hands four times in the direction of normal engine use (normally counter clockwise, from your position, facing the cockpit).
Each time the prop completes a 360-degree turn one cycle will be completed on each cylinder. You will hear a squishing sound and feel some hydraulic resistance to the movement of the prop; it should feel the same each time, and if it doesn't your engine may be suffering from compression problems, losing power and causing collateral issues.

Having checked the prop, proceed to open the starboard engine hatch and take, again a look. No leakages, drops or anything loose, including - of course - the four cables attached to the four sparkplugs located on that side, and coming from both magnetos. Check the oil with the measuring device, which is located inside a lid, usually painted yellow. Once you see that the oil level is ok, close tightly that lid and then the hatch.
