a blue leak--oil?

[ssaamm]

Happy spring everyone. Had my boat out on this year's maiden voyage today. I have 2003 90 yamaha 4 stroke on a 1750 fish hawk. I had it serviced/winterized last fall at the local dealer where I bought the boat. It started right away. I was pretty impressed, but when I trimmed the motor all the way up I noticed a bluish oily substance leaking out from under the engine cover. I am not very mechanical. Is this simply a little meaningless overflow or should I be concerned? This has never happend before, and I've had the boat since last August. If anyone has any ideas like--1)whipe it off and see if it happens again or 2)take it in to the shop-- let me know. I'd appreciate it. Thanks

Is it from under the engine cover or around the lower unit? The synthetic gear lubes and alot of the synthetic oils will have a blue-green tint to them.

thank you for the reply. I believe it is from the motor casing. I noticed it when I trimmed the motor all the way up. A small amount ran into the drainage area by the transom. Hope this helps. I asked the dealer, and he wasn't very concerned unless it is a common happening. I still would appreciate any thoughts. Just looking for piece of mind. Thanks

I’ll bet it is fogging oil that did not get sucked into the motor during winterizing.
