Hope this pic comes through & helps (found it on the internet). Forgot to mention if you do have the original turbos from the 475 package the turbo housings have an approx. 3/4" hole in them to bleed off some of the exhaust. This was how Mercruiser regulated the boost. I welded mine shut & put wastegates on.

I may be able to dig a better pic out but you can see under the tailpipe I took the wedge spacer between the log manifold and the turbo and modified it by welding the tube and flange out the back. The flange matches the wastegate flange which bolts to it. For the extra exhaust I welded tubing and plumbed it to the inner transom plate exhaust cavities.
