Compression check is a good idea. Optimax is a fantastic engine. I've got a 200 that still runs like new. Wouldn't trade it for any other. I'd change the oil reservoir inside the engine as the float gets oil wet over time and, even though the oil is being pumped to the engine, the float will cause the sensor to belive there's an oil problem and kick you into the SAFE mode. If compression is good and you replace plugs and oil reservoir you should be good to go. Also, stick with Mercury oil!
