I'm hoping some kind sole will shed some light on a tilt issue. I have just purchased my first boat with an outdrive (previously owned jets only). I bought it from a guy that bought it from a church auction. Therefore there is not much info on it. The engine runs fine and outdrive engages but the tilt mechanism does not push down the drive. I have read the book and unfortunately it keeps calling for a hydraulic pressure tester that I of course do not have. I was wondering if there were any further tests that I can do to determine what might be wrong before I give up and spend my last few dollars at the boat shop having them go through it. Things I have already tried. Checked fluid level, seemed OK but without being able to put the cylinders down I could not get an accurate level. I removed the cylinders from the outdrive and the drive moves up and down by hand fine, seems to rule out a frozen U-joint. I removed the hydraulic lines from the cylinders and attempted to press them in by hand, they did not move in. I either donÂ’t have the strength to push them in or they are the problem. I removed the retaining collar and pulled the shaft out and everything looked good inside (as far as I could tell). No water or corrosion was present. The hydraulic motor runs and seems to labor after a second or two in the up direction but runs seemingly under no pressure in the down direction. There was some talk in the book about hotwiring the pump to determine if the problem is possibly electrical. My question is if it were electrical would the pump run at all? A faulty reverse, limiter, or ??? switch, I would think, would not allow the pump motor to run. As for the specifications. It is a 260 Mercruiser and the book seemed to make me think it was a low pressure system as indicated by an "A" stamped on the pump. The trim cylinders have to hydraulic lines and I have no idea about the rest. I know I have my work cut out for me but I love my projects. If there is more info needed I would love to furnish it. Thanks for all the anticipated help. http://members.aol.com./libames/b1.jpg
