200 ox66 tilt/trim problems/questions

Hi,

I have a 2002 200 EFI V-max that is bleeding down from both tilt and trim. Rate is about 5 minutes from level to all the way down. Fluid level and quality is fine. There is no external fluid being leaked.

I'm guessing that there is a bad valve/seal in the gear pump assembly. Rather than replace every valve/seal in this assembly, is there one likely culprit to my problem?

Here's an exploded view of my gear pump.

Thanks in advance.

It could be any of the valves, each one would have to be inspected.
