How to Install a Marine Exhaust — Tips & Secrets | S2 Ep 72

Practical secrets from our repower: pipe sizing, waterlocks, siphon loops and a custom thru-hull so your engine breathes and stays safe at sea. Want your engine to breathe — not choke? In this episode, we tackle one of the trickiest parts of our repower: upgrading the exhaust system on our Open 66. From enlarging bulkhead holes to fitting a larger waterlock, creating a proper siphon loop, and building and installing a custom carbon fibre thru-hull, we show all the secrets we learned to reduce back pressure, keep seawater out, and make the new Nanni engine perform safely and efficiently. We cover: - Planning the exhaust route and enlarging bulkheads - Increasing pipe diameter and installing adapters - Proper waterlock positioning and siphon loop setup - Fabricating a structural carbon fibre thru-hull If you’re planning a marine exhaust upgrade or just love boat refit projects, this is for you! 👍 Like this video?
