ABYC is there a standard for how far from the transom water pickups can be installed

[fpjeepy05]

I'm re-powering a 42 Welcraft and there is absolutely no room in the engine compartment to install the thur-hulls for raw water pickup. The closest place would be as soon as you go down stairs into the cabin with is roughly 18ft from the transom on a 42 ft boat. I don't want these pickups to air out at hump speed but I really have no other choice as to where to install them. I can get a closer measurement but I'm guessing 18ft which is about 45% of the LWL forward of the transom. I can get them pretty low in the hull, probably within a foot from the keel. Closer if I stagger them one just in front of the other.
Thoughts?

That seems like too far forward for that kind of boat. You only need one through-hull fitting to feed two engines. I assume you have V8s, so there should be some space in between though.

Can you post a picture? Is it a scarab excaliber or which one?

I agree - not too far forward - I'd find a tight place to fit pickups in the engine compartment.

Mercruiser also makes transom mount water pickups part # Quicksilver 88845-1

Welcraft 42 Excalibur Eagle. Yanmar 6LP straight 6's straight shaft. And they are packed in there right next to each other. I flipped the handle and the Allen pin on one of the seacocks and I was able to fit them staggered in between the engine beds. Not the most convenient place, but life or death I could get to them to shut them off.

Thanks for the help though gonzo, and IMP-ish
