Hey everyone, I am new to this forum. I have a 94 Marlin (wellcraft) with a mercruiser 5.0 inboard. It sat in storage for a few years, I have not worked on it before so I am fairly unfamiliar with it.
The problem began with a slow leak in the trim/tilt. If I cycled the motor all of the way up, as soon it began to come back down again it sounded like it would lose a bit of fluid (sounded similar to purging a water line with air pockets in it, like intermittent high pressure spraying) . I tried the boat out on the water anyway to make sure everything else was working. It was fine the first time, then second time on the water the leak seemed to get a little worse then blew out all at once. Refilling the resivoir and attempting to cycle the trim just empties the trim/tilt fluid into the bilge. The leak is under the motor and I cannot see where it is coming from.
It seams the hydraulic lines pass through the hull and connect to the cylinders outside. The leak is inside, so is there an intermediate fitting where it passes through? Does it sound like a line just blew out or is there a component of the trim/tilt out of sight under the motor? I recently moved an picking up an inspection mirror is next on my list for the hardware store, but for the time being I cannot see underneath.
I have searched around a bit and found lots of great information to troubleshoot the electrical function of the trim/tilt, but not anything yet for my particular issue. Maybe it is just that obvious and I am not seeing it, I am just getting familiar with this boat. I am sure someone has had a similar issue, if anyone has pictures/diagrams that would be helpful as well.
Thank you in advance.
