I am doing 100 hour servicing on a 2020 Yamaha T9.9. I am wondering if anyone has done an self inspection and cleaning of of the engine oil filter/screen (built into the oil pan) that the owners manual calls for. I am thinking it's probably not an easy job. I am also wondering how to get grease into the two small holes on the front of the tilt tube because there are no zerks on the tilt tube. Any advice would be appreciated.
