How to check if the coolant pump is working.
I was out on the boat and the thick hose at the bottom of the coolant tank came off at the engine end and I overheated.
Got towed in!!!!
The next day I put the hose back on the nipple at the engine end (what a mission, you have to push the hose in....clamp down the clamp and if its not on the perfect spot at the nipple the hose will pop off!!!)

The rear hose gets hot so the thermostat is working.
The ride plate gets hot so the coolant is there.
But I keep on overheating in less than 4 minutes and the coolant bottle gets very hot.
So I'm thinking that the pump is not moving the coolant to the ride plate to cool.
Any help is appreciated.
Thank you....
