big blocks and Bravos and merc stock center riser cast iron manifold.................the gills should fit.............the beam of the boat has nothing to do with it,it's the center line of the motors that tells the tail

That is what I was thinking. I just wish the boat wasn't shrink wrapped. I hate to buy something if it won't work and I am pretty sure the stock manifolds and risers have seen their day.

I found a couple sets of gils in a few places all for a really good price.

Can you measure the drive center line from outside? Measure to the top center of the transom assembly. This will be the same as the engine center line. I can go measure mine right now if you think it would help...
