universal 5411 cooling system
I have a 5411 in my 1980 Catalina 30. The exhaust water output is similar to other posts in this thread, but I have seen 5411's put out much more water. I maintain my engine temp after warmup at 140. It concerns me that I have my engine "innards" exposed to salt water all of the time. I am considering removing the thermostat so I can flush the cooling jackets with water starting with lower pressure garden hose and move up to using a pressure washer to throughly flush the cooling jackets and possibly even use a vinegar rinse--leaving the vinegar in the engine for 24 to 48 hours at a time before rinsing it out.
I would also like to do a mod where I have a 3-way ball valve (mounted in cabinet under sink) with 2 inputs (salt water and fresh water from water tank) output to engine. That way it would be easy to fill engine with fresh water each time you turn engine off
I would appreciate comments from people on both the flushing idea AND the modification.
Thanks
