tilt/trim problem on johnson

[mattttt25]

98 johnson 150hp oceanrunner. when i trim it down from full up, about halfway down it starts shaking. once its down most of the way, it operates normal. coming up it doesn't do it. i checked the fluid at the beginning of the season, and it was full. any ideas? thanks-<br /><br />ps. i'm in the water, so its stays in the full up position most of the time.

mattttt25- Not sure if its the same problem I have run into before but its worth the look.<br />Check the tilt tube thats where the steering conects. See if its worn out of round. I have found this on a couple of motors in the past, but usally on motors with lots of hrs or more that 15 years old! <br />steve

Matt,<br /> You may have air in the system or fluid added is incompatable.Check fluid level again and trim up/down(3-5times) to remove air(if any).Always use OMC Power Trim/Tilt fluid or Dexron II automatic trans. fluid.Using a substitute will give bad results.Make sure all the grease fittings the motor tilts on are well greased(OMC Triple-Guard).This will prevent binding.Lube any non-greaseable pivot points with penetrating oil.

thanks guys. i used omc when i topped it off and ran it up and down per the manual to expel air. i think it may be the greese, i haven't hit the zerk fittings in awhile. thanks-
