I tried searching for info on the bushing replacement for rudders but found nothing. My boat is a 97 pre2150wt the rudder bushings are wallowed out due to not greasing them (my dumb). The job looks simple enough to replace them, if I can get squeezed under the gas tank. Anyone done this job yet? Is ther anything I'm not thinking of? Can you get the parts online or do I go to the dealership. Thanks
