    Thru hull exhaust

    Yes I have. I know it’s loud but I was going to just cap the bottom so I could always hook it back up if I wanted it. Could I just go to a muffler shop and have them make me a piece of exhaust pipe shaped like an S or does it need to be marine rubber exhaust

    Thru hull exhaust

    I don’t know the history off the boat to be honest . I just don’t see this big of a boat having a small block . I definitely want thru hull . What do you think would be the easiest way to achieve ? The elbows or headers ? Where is the best place to buy headers or elbows?

    Thru hull exhaust

    Bought a Marlin 26 with 454 . the engine has been swapped from a merc to a Chevy 454. The exhaust does not line up with thru hulls . How can I connect it ? Do they make a flexible enough pipe?
