At least get a half FWC system installed. The cost can be
minimized if you do it yourself. It's not too hard. Raw salt
water cooling will shorten the life of the engine and
cooling sys parts dramatically. With a half system, the
exhaust manifolds are still raw water cooled, but they're
cheap compared to the damage salt water will ultimately cost
you. If you trailer the boat, you can flush the raw side of
the system with muffs, and remove the drain plug in the
bottom of the manifolds to drain them. In this way, they
will last a long time.

I have a 5.7Liter with a Alpha drive that I will be using in salt water. Is
there anything on the market that will allow me to connect a garden hose to the
motor to flush out the system or will I have to put muffs on the outdrive to do
the job?
