How about some pictures of the fitti ng and the set-up inside the boat. I might consider doing this myself instead of tapping into my cooling system like its set-up now.

i take pics right now but have no way of posting them I will give a url.
Be back in a few.

here is pic. This one is slightly longer than 3/16. maybe 1/4.

This pick-up go's straight to a sea strainer then unrestricted thru the intercooler,the only time the intercooler is getting water is when your under way. Yes some people disagree with sea strainers but for the intercooler it is a must. Also with such a small amount of the pick-up in the water your chance of picking up something big is SMALL.

oops forgot the inside photos will go take them hang on.

Where do you get that fitting? I looks pretty easy to install, you counter sink the bolt holes and they go into some kind of bracket on the inside?

Available everywhere.......
Drop through pick-ups are commonly used on cats.

No bracket as the flange act as a strength and sealing surface.

here are a couple of photos from teague marine.

Well looks like I have another project to do....... At least this one looks pretty easy and inexpensive, except for the seperate sea strainer. I guess it's pretty important for the intercooler not to be tapped into your cooling system?
