Yanmar 6LPA-STP Air Intake Diameter

[Mark Laurnen]

Hello all. I am remote from my boat,bu working with Starboard Marine to design an improved crank case ventilation system. Short of removing the OEM air filter and physically measuring the diameter of the turbo air intake when I get to the boat, does anyone know this number for the 6LPA-STP? My understanding is that it is different than that of the 6LPA-STP2. Also, do any of you know the shape (straight vs elbow) and diameter of the crank case outlet fitting? I appreciate the information if anyone has the numbers off of the top of their head. Thank you.

Pretty sure Crankcase is 15mm (5/8”) and turbo inlet is 75mm (3”)
