in-line 6 overheating problem

[spareparts]

Fisrt of all, I haven't seen many inline 6 motors with closed cooling, post up a pic of hte set up if you have it. If it hasn't been done within a year, go ahead and replace the raw water impeller in the lower unit. If the blades are broken off the pump, make sure you find them all. i wouldn't mess with teh ciruclation pump or the closed cooling till you know for sure you have good water flow to it. Odds are, its the raw water pump
