was wondering if anyone knew the measurements of thrull hull exhaust cutouts for a 16 with a small block... seems like it would be easier without the engine in there ... thanks in advance

I am sure the X-dim is the same and the stringers surely are. Maybe it will help :)

TM, "X" dimension IS "X" dimension. The crankshaft centerline in relation to the transom and bottom of the hull is a constant unless you change it. A Bravo is a Bravo. There are no differences. Whether the Bravo is hooked up to a Small Block, a Big Block etc. Alphas and Bravos now have the same cut out to boot.

The reference to hull bottom is unchanged. The places to look for "work" are between the stringers and such.

The BB is wider the exhaust outlets are further apart.

I thought i had them here after cleaning up the office but couldn't find it, Lenny's drawing looks familiar. Easily checked by measuring the distance between the center of the risers and the height looks about right too.
Need a 4-1/8" hole saw ?
