Re: Steam

 

 

Depending on the air temperature and humidity, you may notice more or less normal steam coming from the exhaust relief port.  Nomally it is most noticeable when coming down off plane when the exhaust components are very hot and the slower motor speed forces more of the exhaust gases and steam out the relief hole.

Our water temp is around 50 to 53 deg. I’m trolling for salmon in Northern California

Re: Steam

 

 

Steam is normal, some motors exhibit more than others due to exhaust system designs and water flow besides environmental conditions.

Exhaust gases vary at times from about 800°F to 1500°F depending on engine load. Water is sprayed into the exhaust for both cooling and noise abatement and some turns to steam. At high speeds it exits the propeller but when you slow down it will exit the exhaust relief port.
