Thread: Exhaust Manifolds Cracked & needing INFO

  1. #1

    Default Exhaust Manifolds Cracked & needing INFO

    Both of my Exhaust Manifolds are cracked almost in half, guess the guy who winterizes got me. What I would like help with is what will fit and hope where to get on a sort budget. Yes called around to the shops.
    It's a 1977 ? Volvo Penta which I have been told is the same as a 350 Chevy block? I'm working on getting them off to I can take and compare if I do fine. But info could help if I got to buy outside!
    So if some one has a pair to sell super, I want to get in the water some day this summer.

    Default Photo of what I'm looking for

    It's heck being on a budget ( I'm just fixing it not my boat) but thought I'd add a photo of these puppys. Found some but they look different, same small block to head bolt pattern, has to be, it's just the cooling water part. Couldn't this be just rehosed for in & out.

    What are they made of? If cast iron they can be welded. Let your fingers do the walking for a shop that advertises for cast iron.

    If you canít find one or not able to get it welded, you could consider making one. I had a exhaust manifold that I could not weld the crack no matter what I tried, it just kept cracking after it cooled. I end up spending less time making one than I spend trying to welded it.
