93 Blaster, Head, factory mod pipe, ported etc etc. (stock waterbox)
Overheated waterbox issue..
so a few weeks ago while at wavedaze my entire pump area was stuffed with sand. This happened from a result of dragging the ski around the beach and putting it back on the trailer.
Later that night stopped at a car wash to spray the ski's off and wash the sand away.
2 days later I take the blaster to the local river to run some freshwater through the ski. After about 5 minutes of riding i can smell the ski running hot and can see a tiny amount of steam/smoke coming out the hood. All pissers (head and pipe) still had strong flow out water coming out them and the water coming out did not feel any hotter than usual. Once back to the dock, lifted the hood and can see the waterbox is extremly hot. Sizzling, steaming, smoking whatever you wanna call it. It actually melted the 90 degree rubber between the mod pipe and waterbox. And discolored the waterbox where the rubber hose comes into the box.
So i just assuming that a got a block or poor flow coming from the cooling line. A few nights ago I pulled the ski apart to start blowing out the cooling lines. The only problem that I noticed was the main cooling line coming from the pump to the exhaust manifold had what I would consider a slight restriction. I blew through the line and could hear/see I little bit of crap come out at the pump area.
Is my opinion correct that even a slight restriction would be enough to only over heat the waterbox? I would assume just enough water was getting in to keep the head and pipe cool and there was nothing left over to cool the waterbox?
Opinions...any thing else I should look for?
Thanks Russ
