  • How do I bleed my trim cylinders?

    I was just wondering how it is I should bleed my trim cylinders. The boat hasn't been used in around 8 years, and the cylinders are only connected to the lines and not the out drive itself.

      If its mercruiser they say just up and down a few times while keeping an eye on the fluid level.. Eventually all the air will be removed.

        for me, that's the alternative method to use. there is a bleeding procedure that is to be used if the above method don't work out. also for me. in both methods. the trim rams need to be disconnected from the drive at the aft pin. both methods require you to hang the rams vertical too from a quik read of the s/m that covers my 1975 system.. of course we still don't know if it's even a mercruiser.... so anything said, could be null and void, depending on what the op has..

          If the lines have never been disconnected they may not even need to be bleed.If you don't have puddles of fluid anywhere you should be able to just run them up and down a few times.They will bleed themselves as the fluid passes through the pump if there is any air in the lines.Just make sure you keep the pump full!
