I pulled my upper drain plug to check for fluid contamination and found actual metal shavings on the magnet. This engine was new in 2015 and I only have 10 hours on this engine. I am going to get some gearcase oil and a pump tomorrow and change the fluid. Is this normal or have I got something going bad? I am a auto mechanic and am used to small black graphite looking shavings but these were actual metal shavings ranging in size from about .050 to .100 thousands in size. please advise.

See your dealer and do not use the motor with metal chips or steel shards on the magnet - a fine fuzz is OK and normal
This is a photo of what I found. The plug on the left is what came out the 2nd time i put the upper plug in. The shavings on the paper towel are from the first time I pulled the upper plug. The plug on the right is the lower drain plug that did not have any shavings on it. I drained the gear case and found no shavings, just a very slight glitter in the fluid. The last time I put the upper plug in it came out clean. Then I Ran a couple Q-Tips in the hole and they came out clean. Could these be leftovers from machining or do they indicate a more serious problem for sure.
Those chips are not machining residue unfortunately. Time to visit the dealer
Thank you for your speedy reply. Even though this is not what I wanted to hear, It's better to be proactive than ignore a problem that may bow up into a full blown failure when its not under warranty. I will post my results as soon as I get them.
From the residue I am guessing that a bearing is coming apart or a gear tooth chipped and is grinding everything up as the motor continues to run. Had you run aground or hit anything a long time back? If so, often a tiny crack develops in a gear tooth that took the brunt of the impact. Over time it widens until something lets go.
Keep an ear open for any unusual sounds and do not venture offshore by yourself. Check the oil again in about 10-15 hours of running time.
