Your motor is basically a F150 with some changes, including a larger throttle body and different gear ratio. Check your owner's manual, and I believe the first oil change doesn't even require a filter change. (I did change mine, however.)
The oil filter is a [SIZE=9pt]YAMAHA 69J-13440-00-00[/SIZE], and I have cross referenced it to be the same filter as Wix 51394, Fram PH4967, Purolator L14476, Motorcraft F836, Bosch 72167 and many others. These are available at most any auto parts stores for a small percentage of what a marine dealer sells them for.
I would hate to meet that little Japanese man in a dark alley that tightened the oil filter at the factory. It required an oil filter wrench and a strong arm to remove the filter.
You'll need 5.7 quarts of oil with a filter change. My dealer quietly told me to use 10W30 high quality dino motor oil on the first oil change. I'm running Delo universal oil in my boat. Next oil change, I'm switching to Mobil 1 EP--a far superior oil to plain Mobil 1.
You will need a couple of $1 crush washers on your lower unit and an $5 oil drain plug gasket.
The Yamahalube 90 weight lower unit grease lists @ $10.50. If you invest in a gear lube pump with the Yamaha end, one quart can do the job.
Before you drain your engine oil or lower unit oil, it's best to raise your power trim way up in the air and leave it 30 seconds or so. Then, drop the motor down to where your anticavitation plate is parallel to the ground.
