Ok guys don't mean to keep pestering with my motor problems but yall have good advice and I have looked and looked and can't figure out my latest problem. I decided to take turtlebaits advice and change my impeller so I had dad pick me one up. I have done enough looking since dark tonight to know that I should have bought a kit, which I may still do. Anyway I went out to the motor this afternoon and dropped the 4 bolts holding on my lower unit and I could get it to drop a couple of inches but no more. I put it back together and went reverse, then neutral, then forward each time putting it back together and when it wouldn't fall I moved the throttle a little. Again it is a 25 mercury two stroke 2005 model. I figure I'm missing something small but don't know what it is and would really like to learn how to do this so I can keep doing it. I already change the lower unit oil and grease the motor. I like to do stuff myself but don't want to tear my motor up.
