Yamaha F100 squeaks when accelerating

My 2000 Yamaha F100 squeaks when accelerating, when it is up and running it stops. Could it be a loose belt or what? I have had no troube until now. Please help me!

Wouldn't be the drive belt. They are cogged and the engine won't run very well if it slips.<br /><br />Maybe a prop spinning on the hub? Air intake noise? Need better description of the squeak.

Its the kind ow unsteasy squeak like a squeak on a loose belt on a car except quieter. It could be intake now that I think about it,

If it's chirping, it might be a head gasket.
