I would not recommend drilling it out either. Unless someone replaced it with another elbow, the hole is already there. I’d try some lacquer thinner on the elbow until I found the hole then clean it out with a wire or something. If the water pump is working the powerhead will still get cooling water regardless if this tell tale hole is flowing. On the other hand, just because this hole shows water flow does NOT mean the powerhead is seeing the cooling water. I believe on these motors this hole is actually in the system BEFORE the water passes through the powerhead. Someone correct me if I’m wrong on that. Flow at the tell tale shows the pump is pumping but that is really all it tells you in this case.
