    "alot of mis-information and bad assumptions in this thread... I always advise people that if ur not 110% positive about a fact, dont say anything at all.. that's how rumors spread, that's how false info spreads

    yes.. it is FACT that when the ski is operating the flush port is the main EXIT of the cooling system. NOT THE EXHAUST. the flush port bleeds out the excess pressure in the cooling system. if you put a fitting in there and shrink the opening, you have now increased pressure in your intercooler, and in your j-pipe and have slowed the flow of water thru your intercooler (less efficient you COULD argue)... and you are now forcing more water to go the other way... which way? ...into the waterbox. water in your exhaust causes back pressure and lowers your rpms.

    now whether the flush fittings will made a noticeable difference, that may vary from climate and conditions and skis... i advise my customers to remove them, but i assure them the ski will never blow up or be hurt from leaving it in there, it's just not the most optimum equilibrium for the cooling system... it was designed as a pressure bleed off point as the MAIN water dump of the cooling system

    when you flush the ski... you are REVERSE FLUSHING... you are pushing water totally in the opposite direction of what it normally does while it's in the water... and a main reason for this is also because by reverse flushing, water is now coming out of the internal pump inlet, and causes the water to splash onto the rideplate which lets your rideplate be a heat exchanger out of the water also.

    if you drop the nose of the trailer while your flushing, you can pretty much run the ski FOREVER without an overheat issue bc the rideplate will be getting cooled which is what cools the engine... naturally the carbon seal is the time bomb... i actually periodically spray water on the carbon seal in the hull if i need to run a ski on the flush for a very prolonged time for service

    so while you SHOULDN'T leave it in.. you will never hurt the ski by doing so... u'll keep the exhaust cooler! .. but it wasn't designed that way. hot exhaust mvoes quicker. move water flow thru intercooler keeps it colder, less pressure in jacketing and intercooler is better"

    Re: hose quick disconnect

    Awesome answer! I did notice that if you look into the flush nozzle the opening is about half of the threaded area for the hose. So... If I was to leave the quick disconnect in place I don't think that I would be bottle necking the water flow
