DF115 Whine /Humming noise after revving up and idle

[justcyber]

Hello,

Has anyone else ever had a issue with their motor making a weird whining noise after revving it up and then putting it back into idle? Video is attached.

I have replaced the fuel/water separator and the primer bulb. I made sure that fuel/water separator was full of fuel by using the primer bulb. I have also tightened down all the clamps on the hoses to make sure no air is getting into the system.

Also, does the motor usually jerk a little while it is in idle?

Hi! Check my thread: https://www.suzukioutboardforum.com/...-noise-at-idle

Sounds exactly like my DF100A 2013!

"edit" Oh! i see you have posted in my thread.
After the fix with the fuel supply i havent had any issues with stalling engine. But i think the noise is still there, my noise comes and goes.
I did also lube up the driveshaft.

I think I have found the location to where it is making that whining noise. I took a long screw driver and put it up to my ear prodded around and got to where the oil filter is located. It is super loud right next to it and when I touch the oil filter I can feel A LOT of vibration. Is that normal for these engines?
