Difference in Exhaust Water Temp

[tahoejag]

Just ran boat on muffs checking for plugged riser, etc. Noticed one side of the exhaust water was cool and the other side was very warm. Boat was up to temp (170 ish) Is this normal for one side to be so different from other or what would cause the temp diff?

Ayuh,... Quite normal...
Water takes the path of least resistance...
