Hello All, I m stumped and hoping that some of you can shed some light on an issue that I am having. I took my boat out a couple of weeks ago and ran fine. I did notice that when I started it up at the dock, it seemed a bit sluggish. Sounded like the carb had something in it. In any case, I rev'd her up a few times and ran fine all day long. Last weekend, we wanted to go out and it wouldn't start. It turned over fine but just would not start. I have done the following. Batteries have been tested and they are good. I have good spark and definitely smells like fuel. Replaced and or cleaned the following: Flame Arrestor - cleaned Replaced the distributor cap, Distributor sensor, coil, and plugs Changed out the oil pressure sensor Checked the kill switch I have read on other forums that sometimes the ignition switch maybe the cause or that perhaps I should drain the (raw) water from the engine and manifolds? Not sure what else to check or replace. Any feedback or something to try would be greatly appreciated. Thanks all in advance.
