I have twin KAD 42 A engines w

I have twin KAD 42 A engines with DP-1 Sterndrives I noticed this weekend that after getting up and planning and trimming out to 3 on the VP trim meters the port trim after a minute or two would slip down to 2 then to 1 and so on. I would have to every few minutes trim back up to three. Any thoughts.
 
"assuming no external oil leak

"assuming no external oil leaks, could be rams, or pump. need to pressure test to find internal leak. special tool required."
 
Scott is right but it is more

Scott is right but it is more then likely the Ram all it takes is a little pitting of the chrome and it will break the seals.
