Gear Change Noise

[Fedboy]

Hello,

I recently got my outboard running however when it goes into F or R gears it makes a whining noise. it doesn't make that noise when it goes out of gear though. any advice?

linked is a video of it so its not just my words trying to explain what it sounds like.

Is it something I need to be concerned about?
