My boat is freshwater only, relatively low hours for an '87, and the manifold is a bit rusted and has been leaking slightly for a few years. Engine has been well maintained and running great. It seems to be cooling ok, though one side seems a bit hotter than the other. I've been afraid to try and change out the manifolds and risers because the job would be tough due to the tight engine compartment, but mostly due to the fact that more than likely, at least one or more bolts will break since these are the original manifolds on a 1987 Merc. Any advice? 5.7 L merc, alpha 1
