Holley intake efi 502
 

New mimber just signed up my first post and first power boat baja outlaw 33 2000 I've been restoring. Twin 502s mag mpi the boat runs great tops out 70 mph. Well I noticed I had water in oil so pulled the intake off and it's bad dont wont to repair it can't find one and only won't a new one. So was looking at the Holley intake efi (300-564) and the 1200 cfm throttle body (planing on pro charger) what's your thought thank RJ

I don't know that you need the 4500 flange, the 300-563 is for a 4150 throttle body,
