    Exhaust manifolds

    Looking for mercruiser exhaust manifolds. Would like the one piece model for 1997 4.3. (Part number 807294) In the event I have to convert to the 2 piece model, will they be the same height once installed as the 1 piece version?

    PLEASE help! Water intrusion

    Ok so long story short-- Did an oil change and ran then found water in my oil and everything told me it just couldn't be a cracked block, maybe head gasket.
