Hello: I am a very new owner of a 2010 Sea Ray 175 bowrider I/O and a couple of weekends ago, my prop hit bottom and dented the prop. I thought I forgot to raise the drive but when I put it back on the lift, I noticed the sterndrive is not raising all the way. Maybe just one third of the way up but it goes all the way down. I hear the motor running when I operate the trim switch and it stops when it is supposedly all the way up but when I check it is only up part of the way. Any suggestions? I must say, I know nothing about engines, motors etc. Are there any simple things I need to check before I take it to the mechanic?
