When down and going into reverse the motor pulls up. Light reverse is
fine. Its when your throttling up in reverse a bit that the motor pops
up.



When in forward or neutral the motor is not locked in the down position.
This is done intentionally so that if you should hit an object while going
forward the motor is free to kick up. The forward thrust of the propeller
will keep the motor in the down position.




When you shift into reverse there should be a latch that locks the motor
down.

NO... this unit does not latch in reverse. It is all hydraulic. The
tilt pin only limits the downward travel if it is installed or retained
at all. The latching mechanism, present on the outboard, is disabled
when the power trim & tilt unit is installed - all the parts are there
and intact, it is just blocked from being used, into the "Release"
position, with the trim brackets installed.



Look at the motor mount, down near the bottom of the transom. You
will see a series of holes through the mounting bracket. Through one pair
of these holes there should be a rod, perhaps 3/8" diameter. The hole you
select for this rod establishes the full down trim position. I am not sure
that I am seeing the rod in the picture, which might be your problem.

On the motor, about 6 inches or so below where the lifting cylinder
attaches, there should be a hook that is supposed to engage that rod. If you
shift the motor in/out of reverse you should be able to see that hook flip
up.

Possible reasons it doesn't work:

1) The rod that the hook is supposed to catch is missing.

No.


2) the hook is jammed.

No.


3) the shift mechanism has gotten sloppy and it doesn't move enough.

No.




I am sure that once you see the motion of the hook it will be obvious what
is wrong.

The latching mechanism, present on the outboard, is disabled when the
power trim & tilt unit is installed - all the parts are there and

My guess would be that the pressure relief valve screw has been backed
out, or the needle/seat is worn and letting oil through. This is the
screw on the pump body that you would use to raise the engine if you
lose the pump motor or electric power and need to rasie the engine for
trailering or beaching.

Check this out first...
