2006 X-10, MCX, approximatley 110 hours

the lake we run is is considered very alkali... over the past little while we have been slowly getting less and less heat out of our heater.

decided today to pull the heater core out and it was plugged solid with scale... ran a bunch of CLR through it and it seems that everything is running better but we still arent getting the heat out of our boat that we have been previously.

2 questions.

does the "Y" fitting really make that much of a diffrence?

also ive heard that the heater core is from and older ford... does anyone know what it is? im thinking that with the alkilinty of our lake that if i can find an inexpensive replacement that i may just replace it anually...

The Y fitting makes a huge difference at idle and lower RPM's. Less so at mid- to high-throttle.

As to replacement - look at this post (http://www.tmcowners.com/teamtalk/showpost.php?p=397836&postcount=30)...

Or you can pay SkiDim $83 (http://www.skidim.com/prodinfo.asp?number=H-202)and get the entire grey box with core installed. No worries about fit then.

The Y fitting will come with a little diagram that explains it. Basically, you disconnect the return line from where it comes out of the circulating pump and plug the hole with a screw-in plug, slip that hose under the engine to the area of the raw water intake line...cut the 1 1/4 inch raw water hose before the raw water pump with a hacksaw (it's wire-wound)...slip the Y fitting in place to the two ends of that 1 1/4 raw water intake hose and secure with hose clamps. Attach the heater hose to the small limb of the Y with that limb pointing away from the raw water pump.

Try looking for "Y pipe"
