I have an aluminum block engine in my wakeboard boat which is built for the lakes, now i live on salt water and was wondering the effect saltwater would have on the engine block as water goes through to cool it.
Saltwater is death to aluminum, no matter what your boat dealer says. Be aggresive in monitoring the protective anodes in your engine and on the prop or outdrive - replace when 20% or more eroded. Flushing is good, but eventually your engine will be destroyed by the salt.... Be especially wary in marinas where stray electric currents can cause electrolysis that can destroy the metal parts in your engine in a very short time. Watch zincs carefully if you're in a marina.
Munch Munch better flush when done.
Listen to Randall. A heat exchanger is much cheaper than an engine block and heads.
it will eat it up... install a heat exchanger
