westcoast exhaust issue

[goatse]

I was riding my 650sx last season and I was hammering down and all of a sudden it started bogging overheated in flooded out the hood. I towed it to the shore and realized that the sleve/gasket that holds both sides of the exhaust together was blown out. I wrapped it up and called it a day. Well I'm finally getting it ready for summer I installed a new gasket and I realized that A brassfitting had also broken off in the exhaust. So I used an easy out to remove the brass fitting from the exhaust. While I was doing that I must have torqued down too hard and cracked the port that the fitting goes into. So my plan was to fill the port in by welding the gap, then i was going to use a tap set to put a new threaded port-hole in.
I am out of town, so i have my riding buddy handle the drilling/porthole..
I've already had the port welded/filled in.
My buddy seems to believe that the fitting doesn't actually allow water through. From the way it was explained, the port isn't a complete hole and is factory made more like a plug? I am not sure if I'm on the right page as him, but maybe you guys can help me figure this out? I have a general understanding of mechanics and it doesn't make much sense that the fitting would allow water to pass through the exhaust, then again it is a marine engine and i have even less knowledge on the marine engines, so maybe I'm wrong?

Basically I'm trying to figure out what my buddy should do with this already-welded copper fitting port. Any help? Thanks in advance

The westcoast pipe is plumbed the same as a factory b-pipe, so look at pictures online for single cooling of a b-pipe and yours should be the same (look at factory pipe.com and read the install instructions for the b-pipe). You could run dual cooling but shouldn't need to, either single or dual, your pipe fittings are the same.

Did the ski ever run right with that welded up? How was your cooling run?

Generally that fitting is an important component of cooling the head pipe. Water goes in on fitting on the head pipe and out the other. I think a few pipes did have 3 fittings on the head pipe but not the westcoast. That fitting being plugged would mess up the flow through your head pipe. There is a small hole that injects water into the exhaust that you can not access (just like this the b-pipe has 3 adjustable screws, the westcoast has 1 non-adjustable hole.)

That hole being blocked would make the head pipe run extremely hot. You would be lucky if you only melted the coupler and didn't do any piston damage. Hopefully the exhaust leak richened up the motor and killed it before the Pistons could over heat.

Post pictures of the cooling setup you had prior to this, and let us know if the ski ever ran right before this happened. Don't run that boat again before you get clarification.
