My boat has been sitting for two years. The motor seems to be 'frozen' in place because it wont turn. Its a late 70's maybe early to mid 80's 80 HP Mercury. Do these have some type of lock that makes it so they wont turn? Or do I just need to lube up the little metal bar that goes into the motor? If so will WD40 be ok?<br />Sorry for such newbie questions.. but what more can you expect from a newbie?
