This sounds like the sort of thing you could chase around forever….Do both engines have similar needle valve settings? There is no thermostats, so engine temp isn’t an issue. You state that both engines run great. I guess I would try giving the rig a nice long high speed run, then shut off both engines and tilt them up, maybe at a beach somewhere, to see if there is any drool. If not, then I’m thinking it is a low speed/overboard drain issue. Some engines just do this, while others don’t…
I’m assuming you have made sure this is not a leaky gear lube situation.
What are the plastic jugs with the tubes seen in your picture?
Sorry, just don’t want to see you rip these beautiful engines apart chasing down this situation….
