Re: 87 Bayliner with a 85 hp Force Tilt and trim problem
Either the cylinder has a bad seal or there is contamination in the the line. I found that a small amount of contamination will clog the check valve in the pump manifold.<br /><br />If the cylinder is not moving at all, I suspect you hear fluid flowing through the internal pressure releif valve and the check valve has crud in it.<br /><br />Remove the check valve, with a hex key, from the end of the pump manifold. You'll see a little dimple in the face of the plug you take out. That is the check valve. It should move easily when depressed with a piece of wire or paper clip.<br /><br />If there is any dirt or discoloration to the oil, drain and replace it with straight 30 weight non-detergent oil.
