Greeting to All!<br /><br /> I just found you guys, and thanks for being here!<br /><br /> I have a problem and I hope you all have the answser fo me.<br /><br /> I have a 1985(?) 20' CC SportCraft Fisherman with a 1.6L (150hp) OMC SeaDrive.<br /><br /> My problem is with the tilt/trim hydraulics.what it is doing is it want to "slam" back in to the trasom under load,above about 2300rpms.<br />It will hold the outboard over night with no leak down,I marked the rod with a black felt tip on the rod of the upper ram,no leak down in about 20 hours. I changed the hydraulic check valve block out with a used on that I bought. still doing the same thing. this is on the upper ram. <br />Is this meaning that my ram is bad?<br /><br /> I did a search and did not find anything like this. But I did get 20 hits total in the search.
