My 5.0 Volvo Penta GL-E, Is acting up. I let it sit from memorial weekend, till August 9th, I needed a new starter and got it, Now the boat started perfectly fine, we started it up and let it run with muffs on a few times everything was perfect. Yesterday we got it started, it was idling perfect it sounds healthy. Everything was good, Till I rev'd up the engine. It was revving fine & then boom just stalled. As if there was no gas. Now it doesn't want to start, it cranks and everything and it'll start for a few seconds then does out again. The last time spark plugs were changed and carb was adjusted was in summer of 2012. What do you guys recommend and where should I start.. I'm really worried, my battery and connections are fine. I'm just worried we might have put a wrong connection or something on the started but it's all fine. It just dies out... Another thing also is when I switched the fuel and water separator filter in May, It was a new filter that was purchased in 2012. It was still in the box new but it had dust particles on it from sitting, what could cause all this, and where should I start? Thank you any help is truly appreciated.
