The exhaust bellows was gone, and the u-joint bellows was torn. The bellows are nothing but seals that keep water out of the drive. The exhaust bellows is not a show stopper (it directs exhaust through the prop) but the u-joint bellows must be good or else water will get to the driveshaft and drive, killing it in no time. The trim switches also have bad wires. There are 2 of them, one that connects to the trim gauge and the other to the tilt motor, stopping the drive at full up and down. These have to be replaced.
