You can change all filters, oil, gear lube, impellors, zincs, etc. yourself if you are able and capable. You can service and repair anything you want on your outboard. You own it! Yamaha doesn't own it. No need to pay and wait for "Service" by an authorized service center which, I hate to say, can sometimes do poor job. FYI... I stopped using that grossly overpriced Yamalube years ago for oil changes... As soon as I had a good break-in on the outboard I switched to Mobile 1 Full Synthetic as many have (available in 5QT jug at Walmart). Some say it may foam, others say it doesn't have this and that and I say BS. If it can handle 15,000 RPM in a Formula 1 race car it itsnt' going to foam at 6,000 in my outboard. Get a replacement filter, some Mobile 1 FS and do it yourself. Quick and easy but remember... with a full oil change only put in as much as is recommended for your engine. The dip sticks on these engines show a wide range and so long as you are anywhere above the low end of that range you are fine. DO NOT FILL IT TO THE TOP OF YOUR DIPSTICK range as you would with a car. I think you'll find you are fully filled per the specs and find your oil level around the middle of the dip stick rage.
