Couple of quick possibilities are the bleed screw that lets you move the engine when the engine is off, left side of trim unit, may not be fully closed....just loose enough to leak. Next could be that you have a leak somewhere and your fluid is low....outside chance.....that is the screw on the rear of the pump assy and full is even with the top of the threads....if it had any more fuel it'd run out, engine in full up position when checking....put the screw/plastic nut back in before you move the engine from full up.Tikitech, your saying a brand new trim system is leaking ?
How about a picture.Yes it's a brand new motor never been on the water, mounted this spring on the boat. Had come in from the factory in January. On the bottom new trim cylinders there's what looks like JB Weld type stuff plugging the holes where I assume a plug screw is inserted after machining the passageways. I'm still waiting for Mercury Tech to contact me back.
How about a picture.
Well the OP's original issue could be the bleed down built into these new trim system's what I quoted is directly from the Mercury manual.No idea. Wouldn't think Merc. would build something like you describe.
