Power Loss

[aspilios]

Hey all,
Im new to this whole golf cart thing and its not my golf cart im posting about but its a buddies. well we were messing around with his yamaha gas golf cart in the woods and we saw some mud. so being ourselves we hit it made it about 4 feet and then got stuck. having the golf cart floored for about a minute the wheels were spinning and everything then all of a sudden it just lost power. so after getting it out and back up to the house it still has no power at all. it runs but if you have the pedal down all the way the cart will barely move. we checked the intake and filter and they were dry (we suspected it sucked up water). really the engine is spinning slow and the belt is not turning at all because of the lack of power. does anybody have any ideas of what i could look at or how to fix this?? thanks
happy holidays to all
Alex
