Hi,<br />I own a 1989 Bayliner with a Force 125 hp outboard. I'm having a problem with my power trim & tilt. It is working great as far as moving the motor up & down. The problem is that when the motor is up it slowly moves down on its own! I've been reading some of the posts & see that alot of them refer to replacing the o-rings in both the trim & tilt cylinders. How difficult is this to do? Will this alone help the problem? Do you need any type of special tools to do this? I was looking at a Doug Russell Parts Catalog on both the trim & tilt to my boat & it looks like the o-rings can be replaced easily. Must be more to it then just that. Any help would be highly appreciated with this.<br />Thanks,<br />BJudd <br /><br />
