Now that I have the exhaust components fabricated its time to start final installation.

The 6" fiberglass "Y" pipe will penetrate the bulkhead on the outboard side of each engine.

My configuration is...... I have a rigid SS fabricated exhaust pipe terminating with a shower head then connected to the FiberGlass "Y" pipe using a Single Hump Trident exhaust bellow.

It seems to me that the Fiber Glass "Y" pipe should sit freely in a cradle to support the weight but be allowed to and move laterally with the expansion and contraction and engine movement.

I'm afraid that if I glass it to the bulkhead something is gonna crack or break sooner or later

Patrick............you have done a lot of these installations.....I value your advise and experience.........what would you do???

Harry,

Do not hard lock any part of the exhaust run to the boat between the engine & the transom... The transition through any bulkhead must be free. I'd leave at least 1/2" of clearance around it after adding chaffing protection.

Thanks Pat
