This was how Mercruiser regulated the boost. I welded mine shut & put wastegates on.
Do you by any chance have pictures of the wastegate setup you put 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.

I see it now, this means the spacer is not water cooled right?

(OP sorry for the Hijack)

The wedge spacer (mercruiser/Gale Banks item) is water jacketed but, correct, my wastegate in/out was not water cooled.
