Bursting implies that the hose contains pressure that might be suddenly released- this isn't the case. The hose isn't pressurized more than a few inches of backpressure. When it's near end of life, the hose will start to crack and seep seawater. The heat will usually drive off the water so you'll see salt crystal trails at the leaks. As others have indicated, you probably won't see much evidence unless you look inside the hose. If the hose has been overheated/burned inside, determine WHY it is failing and make sure the underlying problem is dealt with before simply treating symptoms by replacing the hose.

Your mixer ell could be at fault, so carefully inspect it when the hose is removed. If the hose is consistently running hot enough that you can't touch it, there's a cooling problem. There can be a number of causes, the seawater pump could be worn, impeller bad, the heat exchanger could be obstructed, the mixer ell could be compromised. WHY did it happen??
