Re: 1976 Evinrude 115hp water question??
Your engine does not have the advantage of a overboard indicator (called the telltale) Came out in 1978 when OMC went to the dual thermostat arrangement. Your engine does have a type of indicator, albeit somewhat hard to discern. Start your engine when it's cold. As soon as it starts, hold the palm of your hand back by the two exhaust relief ports at the top of the midsection. After maybe a minute, the vernatherm (thermostat) on the engine will heat up and open. When that happens, water droplets will start to form on the palm of your hand, indicating water is flowing through the powerhead. That's normal and maybe even visible, once you know what to look for.
