I'm betting the problem is solved!

DAY5-Coming back from the last time out, I heard a loud screeeeetch,
type noise, pull the boat and trailer over to the A&W. First thing,
check hubs - yep one is burning HOT and she's (the hub/bearings) shot.
I was able to drop the boat, and get the grease and screwdriver at the
Ace Hardware a block away. So I grease it up, and limp the boat and
trailer home.

I get both trailer hubs professionally worked on and installed new with
new buddy bearings. I take the boat out. Put it in the water and now,
the POWER TILT is not working. I cannot lower the motor in the water
(100hp Johnson OB Javlin). 1) the button works on the FNR leaver. 2)
the hydraulic pump is pumpin (or it's getting juice) so that circut is
good.

I press down on the power trim, and the hydraulic motor goes (like
normal), but the motor just sits there in a forward tilted out of the
water type position. I tried to press the motor down forcing it, and
that would not even work. I press up on the power trim button the
hydraulic motor hums but the motor does nothing?

This is not normal. The power trim always worked, well since I bought
the boat a few weeks ago. I did notice, when I went to pick up the boat
at the trailer shop, hydraulic fluid "leaking" out of what looked like
the right piston that sticks out behind transom next to the motor.
There is two of these piston looking things and there was hydraulic
fluid about 1 teaspoon, on the cement floor of the guy's shop. And
traced it up to that (seal)? around that piston that (One of Two of em)
stick up.

Looking at the back underneath side of the motor, there looks to be a
reseviour next too these pistons things, with a side screwdriver plug
type screw. I'll pull that out and put in some brake fluid? I guess
you'd use that or hyrdaulic fliud? (same thing?)?

Anyone ever fixed a non working power trim that looks and sounds like
it should be working? It's has to be low on fluid? Any help to fix this
one would be great!!!

BTW, I never got to test the auto choke which started the whole thread,
next weekend I hope now.
