I did just that, unscrew the fluid cap, hear it hiss, raise it all the way up add more fluid, take it all the way back down, did that 4 times. This is as high as it goesYes, Those PTT units can trap air, and look to be full of fluid.
Run the PTT motor up and lift tilt the motor by hand. Get some help, if you can as they can be heavy. Block it up with the manual lock and let her sit with the boat level. Now refill the reservoir, replace the cap and run her down and help it up again. Let her sit......repeat a couple of times.
That with the trim button? Looks plenty high.I did just that, unscrew the fluid cap, hear it hiss, raise it all the way up add more fluid, take it all the way back down, did that 4 times. This is as high as it goes
That was pulled up with an engine hoist, lock engaged and then filled when the large middle cylinder was at its high travel point . I could not get the motor to raise up without using an engine hoist. Filled it up until the fluid ran out. Brough it back down and vented the air 3X.Gee, most of those PTT units must be filled when tilted all the way up. If the cap is opened and the PTT unit is not all the way up, the fluid will run out.
You don't need a manual for that....they all work the same. Believe it or not the pumps do burn out. Find a used one or replace the pump.That was pulled up with an engine hoist, lock engaged and then filled when the large middle cylinder was at its high travel point .

the unit still will not raise by itself. I do not want to drop $400 on a new hydraulic unit.
Does anyone have a manual for one of these old 90 HP crossflow units?
OK, new pump motor,are there better deals or is Sierra a good brand when it comes with seal. Does the seal on the center hydraulic s look suspect? If I'm replacing that seal, how do you replace that and where do you get the 4 prong tool to remove the cap?You don't need a manual for that....they all work the same.

I said pump not motor....if motor spins than most likely it's fine.OK, new pump motor,are there better deals or is Sierra a good brand when it comes with seal.

The whole rebuild kit is the way to go.
