Hi all, I was wondering if anyone is able to tell me what the inside diameter/bore of the engine oil drain pipe is on my engine. The one that runs up the side of the engine and has a brass cap on top. I'm looking to manufacture an oil suction type fitting and pump system at work, and forgot to measure the bore!! It's 2.8 Dtronic Mercruiser.
Thanks in advance James.
