Fairly new to a motor over 15hp, and am noticing it's taking entirely too long to start my 70hp evinrude. Once started and warmed up a flick of the key will start it up, but the initial start is very hard. This boat was sitting for quite a few years when I got it but plugs and wires are good and I used brand new gas (a small amount of old gas was in the tank with it). Can anyone explain what might be causing it to do this

There is / should be a way to advance throttle without shifting on the control box.-------Post a picture of the controlls .----Or visit a boat shop , buy a gallon of oil and ask them to show you how to start it.------Will save you burning up an expensive starter.

Oh I read it wrong yes I did have the throttle approximately half way up. Not sure if I was pushing the key in though. I think it was a combination of bad gas mixed with inexperience with a bigger carbuerated engine. Thanks For the response brother

Your motor has an electric primer system. Some people call it a primer pump - it is not a pump. It is a solenoid activated valve that allows fuel to bypass the carb and get squirted directly into the manifold to richen the mix on startup. When you're turning the motor over and holding in the key, the fuel pump is pressurizing the system and the activated primer will richen things up. It does this in place of a choke and operates in much the same manner. Raise the warmup lever, turn key, push key in, when motor fires, hold key in momentarily as motor warms up. Depending on motor, you may need to tease it a little as it warms up. It'll come with experience as every 30+ year old motor has its own quirks.
