I have a 2006 Yamaha F150 four stroke engine. Lately, I hear a high pitch whine that sounds like a belt or pulley spinning. I do not hear it when engine is idling in neutral. When we put it in gear and go slow, perhaps 2000 rpm, the whine is there. Back to neutral, it disappears.
Any ideas? I don't think there is a pulley or belt is there?
