I just bought an older boat with a Merc 115 horse straight 6. The motor has not been run in about a year and I am unable to get it started. There are things I know are working well on the motor which include, the starter (which engages and turns the motor over well) the batter, which i recently replaced, and the plugs (I checked all of them for spark and they all seemed good). The motor seems to want to start when a little gas is squirted into the cylinders but doesnt ever start. It is a little cold out but not too bad, about 60 degrees.
What should I do or check next? I have a feeling it just isn't getting gas. I pump the ball hard but after cranking on it for a while it isn't quite as hard. I am still fairly new to outboards, and have never worked on anything this complex.
Thanks for any input i appreciate it
