Hydrolics

Hi, I'd first like to say thanks to everyone who contributes. This is a great resource for people who want to fix their own boats and motors. I hate dealers, most times they are no help and want $$$$$ for anything.<br /><br />Like my friend, who had a Yamaha 9.9 long shaft and seized it. The dealer said it wasn't worth fixing and offered him $50 for it. I said RUN! <br />He fixed it for $250.<br /><br />Now my question.<br /><br />My other friend has a 21 ft. Sangster with a 140 merc (i think). Well, the trim and leg lift doesn't work due to air in the system and the dealer said he needs to buy special tools to get the air out. I thinks that's a bunch of hooey so I wanted to ask here first.<br /><br />Can anyone tell me how to get the air out? Is it just a matter or filling the resevoir and running it up and then down, then checking the oil level? Or do the lines need to be loosened etc.?<br /><br />Thanks for any ideas.<br /><br />Jeff, BC, Canada

Re: Hydrolics

I've had good luck with just running the pump up for awhile, then cracking the line and letting the air out, just like on a cars brakes. you have to do this on the down side of the pump as well. It takes a few times and make sure the res. is full all the time

Re: Hydrolics

I forgot to tell you but you will notice that the hyd. cylinders after a couple of times will run up and down faster and more even, and the pump runs alot smoother. When the pump runs nice and smooth without skips, you got it.

Re: Hydrolics

Thanks for the reply clearlakeboater. I'll try that and a few other things this week.<br />I've also found a few other posts with trim/lift problems so I will try some of those things too.<br />My friend is a total newbie to boats and a mechanical neophyte. Hopefully I can help him.<br />Jeff
