    Default Alternative wye fitting for heater

    I will keep you posted when the part arrives but I have been told that this $3 Mercruiser part will do the same job as the $54 Heatercraft part.

    I may have to adapt the hose from 5/8 to 3/4.

    It would be nice to have warm air at idle.

    It goes in line before the raw water pump. The raw water pump pulls the water through the heater's outlet side allowing more hot engine water to circulate through the heater core.

    I have to say im glad your only spending 3 or 4 bucks because i think you will be very disapointed.

    The reason the heater is cold at idle has very little to do with water flow, or what part of the engine it comes from.
    It has to do with as the engine idles it cools off because the ENTIRE lake is your radiator. As the engine idles it continues to pump or wonder cool water though the engine cooling it down below 120 degrees. Anytime the engine is cooler then 120 you physically wont feel heat.

    This is the same principle and reason in your car you cant feel heat from the vents will the temp needle actually moves over 120.

    Correct and most dont start to open till 120 and completly open at 160.
    In a boat you have a T state as well and even putting the Y before it your going to get cold water, its the engine working creating heat that is warming up that lake water so fast.

    Give you an idea how much water flows through your engine its as low as 4 gallons a minute to 60 gallons a minute depending on how large the engine is, typical 5.7 is 8-15 GPM

    I just figured out how you guys can warm up your water up there -- do more boating. You'll also need a few more boaters. And for gosh sakes, scrap the heaters and quit wasting heat out into the air.
