Abstract
The idle exhaust pressure relief system in an outboard motor is utilized to simultaneously heat the engine crankcase or other parts of the fuel supply system to prevent the puddling of fuel typically occurring at lower engine temperatures. Because the idle exhaust pressure relief system is inherently operable to conduct hot exhaust gases out of the exhaust manifold only at idle or low speed operation, heat is supplied to the crankcase only at temperatures when fuel puddling typically occurs.
