Mercruiser Woes-What Next?

Be sure to change both of your manifolds, not just the one that is leaking right now. It's pretty much straight forward on swapping your FWC componets over to the new engine. What would be ideal is to have a heat exchanger big enough to cool the manifolds as well, that way you would only be concerned with replaceing the risers when they start to eat away which in the long run would be cheaper. On my Seavette, every thing is FWC for the exception of the risers in which those are made of stainless steel.
