Captains Call exhaust diverters dropped for integrated swim platforms. With Rex Marine exhaust tips with built in backwash preventers and removable baffles.

These have a dropped output to help make them work under a swim platform. These came off a small block Stingray but should work with a big block as well. The exhaust tips have a reduced edge on top of the flange also to assist with fitting under an integrated swim platform.

I have not seen this design anywhere else. Included aircraft hose clamps and the relays with some wiring. No guarantees this will work for your specific application but regular captains call diverters won't work with most swim platforms. I have pictures if you are interested. $500 plus shipping from 23927
