Home › Forum › Ask A Member › QD19 Overheat Question – Update › Re: Question For The OMC Experts
Well I opened up a few motors, and pulled a bunch of parts mids I have to investigate.
I could not find any with the modified drilled hole. I could see how that could work though. If you shot a drill bit on a downward angle, through the water intake tube, almost towards the shift handle, it would "mist" cooling water in that area. Now the downfall of that would be if your lower crank seal failed, the water would "climb" the drive shaft and enter the powerhead easier. If the seal is good, which I assume you would change if you had the powerhead pulled anyways, should not be a problem
The real question is though, why is it heating up there?? I have never seen that before. Only thing I can think of is exhaust is building there, and not getting siphoned out through the snout until you get on plane.
Can you physical SEE the exhaust mixed in with the cooling water when puttering at an idle?
Sorry, Im at a loss, other than if that passage is plugged somehow beneath the plate into the other chamber.
