i was recently out with my boat and the bilge pump keptrunning about once an hour. i removed the engine cover to see if i could find were the water was coming from and it appears it is from the outdrive. does this mean my boot is cracked and leaking? should i replace it? how hard is this to do? i'm pretty good mechanically i've done alot with cars and feel i should be able to do it on my own. if not what isthe normal chargee to do this job? i'll by the materials needed. thank to all that reply....Dan
