an 85 hp engine will heat a small amount of water pretty quickly,because the water is cooling the engine block and leg where the exhaust gasses pass through.
also you will have hot exhaust gasses adding their bit to the water temperature.
if i run my 60 hp four stroke in a tub i allways leave the hose pipe running adding cold water to the tub.
once i left my engine ticking over in a 50 gallon tub after 10 minutes the over heat alarm was buzzing away.
luckily no damage was done,so it is muffs for me now.
