anyone know what this manifold is for?
Hang on to it, genius. That's an extractor manifold with the "banzai" mod. The banzai mod lets you run 61x v-force reeds reeds on a different reedblock and manifold. If you put that on your boat with a 13 degree prop on it, slam the head, and use the matching extractor exhaust it will "smooth" try to rip your arms off. You guys have no idea of the power to weight ratio. Rediculous!!!!!
P.S. Don't forget to dry out the P trap. NOT for bolt on junkies!!!!!!

I remember those sitdowns. There were some guys on RSJS that got them new back in the day. They were called SeaJets. Besides the 900, they had a triple 1300 also I believe.
I just found this on PWCT, maybe it will help. Its hard to tell in the pic for sure if they're the same. Maybe you could contact him for better a better pic of the intake:
