Back again with a question about the ol' tower of power attached to my boat. I took her out on the lake yesturday and we cruised out of the little inlet where the ramp is located. When I gave her some throttle she started to run really rough and then died. She started right up and we idled along for a while, I gave her some gas and again... rough and then died.
I figured it was a fuel starvation problem, so I checked the bulb (it was good). I took the cowling off to make sure things were okay inside. I was hoping for something really obvious like a mouse stuck in a carb or something, but no such luck. I left the cowl off and started her up just to check things out. I had my kid give her some gas while I was watching the insides for something obvious, but the motor ran fine. Took her up to full throttle, and she ran smooth as a top. So we stopped and put the cowling back on, figuring it as one of those worked itself out miracles. Unfortunatly as soon as we started off again, the problem re-emerged.
Once again I removed the cowling and the motor ran like a top, so we left it off for the rest of the trip and had no problems, other than it was a little louder than we were used to.
The only thing I can think of is air starvation inside the cowling, like the carbs are not getting enough air to mix with the fuel while the boat is running at full tilt. I looked all around for some kind of air vents that might be plugged but I couldn't find any? Any suggestions? Should I just drill some holes in the cowling to provide more air, or is there some kind of adjustment I need to make?
Thanks.
