The usual test for ok cooling water flow on an inboard is a quick look over the stern.
Unfortunately, the cooling water outlet on my Hunter 326 is below or at the water line and under the stern, so that there is lots of gurgling and splashing going on with the seacock open or closed!
The exhaust note is different I noticed, but not remarkably so - not for a newbie at least.
Tests for flow rate suggest a bucket under this outlet which is obviously not practical in this case either!
I don't have a temperature gauge, just the warning buzzer!
Any suggestions?
