u/EvLS2

​

has been used for less than 15hrs, this started today and occurs from any speed from 1.5-10 snd gets louder with speed regardless if it's the head unit driving the prop or just water flowing over it in neutral. All functions are working and nothing is rubbing on the prop or propeller. Vibration comes form main head unit. Any thoughts is a help!

Ran this motor for the first time today since August of 24. Was professionally winterized in 24 and stored until today, ran fantastic no issues at all. Sat for 6hrs this is what I came back to. Seal or just unburnt fuel/build up?
