Finally have my engines back in the boat, and want to add a flushing set up so that I can run the engines easily on the trailer.

How do I set this up?
A. Two separate connections, with two deck fittings, 1 to each engine
B. One deck fitting, a tee and two ball valves to isolate the engines.
C. Before or after strainer?

I don't want to place more stuff on deck, so likely will build brackets below the engine hatch for connections ......

A lot is going to depend on how your sea water lines are currently set up. Three-way (tee) valves are probably the most convenient, especially considering the lack of extra space in Magnums. I ran a three-way valve at the input to each sea strainer on my Sedan which were mounted on the center stringer near the bulkhead at the front of the engine compartment. That made them easily accessible for both attaching the garden hose and switching the valves. One thing to keep in mind though if you put the valves before the sea strainers is the pressure of the water from the hose. Most water supplies regulate pressure pretty well but some can be high enough to damage some sea strainers.
