They do make water-cooled turbo's but I suspect they are not cooled in the sense our marine exhaust manifolds are. A nice low profile blower like a B&M would work, maybe even a centri type like a paxton or G scroll(VW). As an update, I finally broke down last night and filled the engine cover recess in. It just looked too restricting in size compared to the new decal. Now that its soon to be smooth, I have greater flexibility in the decal placement. Painting of the top is nearing, I hope to post a couple pics then. Considering adding even more flake to the top than the bottom, secrectly hoping its not noticable.
I did refinish the inlay area on the front of the boat, they previously painted right over the decal adhesive. Does anyone know what the decal looked like in this area for a CVZ? better yet, anyone know where to find one? My CVX 16SS has a very nice looking decal there, but its recess is probably twice as long as the Z has.
