I'm not much of a mechanic, but I'm moderately hady. But I'm scratching my head more than I'm making forward progress. You know the feeling?
My dad just bought this boat and it ran without any problems the 2 hours he had it out the 1st time. Next time out, it started sputtering after about 45 minutes. So he brought it back to the dock where it died and wouldn't start again.
I pulled a plug and checked for spark, nothing! I pulled the wire that feeds the distributor and put a plug in that and tried to get a spark there (not sure if you're supposed to do that or not) and got nothing. With a meter, confirmed 11.5VDC going into the ignition coil. So I changed the coil and plug wires (one had 130k ohms more resistance than the others!). I also pulled all of the plugs and checked the gap and made sure they were fairly new.
With the new coil and wires, the boat ran fine for an hour, then went back to sputtering. My brother took the carburator apart and said it looks pretty clean. Also took the fuel pump apart and cleaned out a chunk of buildup on what appears to be the air intake. (There is a hose that runs from the fuel pump to the carbuerator bypassing the fuel filter--I can only assume that's so it gets clean air?) And for good measure, we drained the fuel tank and filled it with fresh gas.
Third time on the water, the boat sputtered around the entire time. I took the air filter off the carburator to make sure that's not the problem--still sputters. While I was down there, I noticed there was fuel coming out of the clear line form the fuel pump. So that's dumping unfiltered fuel into the carb that I'm pretty sure isn't supposed to be there?
I pulled the oil dipstick after we got the boat out of the water, it smells like gas. That together with gas coming out of what I assume is the wrong part of the fuel pump, means bad fuel pump?
But since I'm not sure the ignition system doesn't still have issues, I checked the spark from the ignition coil. Its orange. I thought it should be blue? Its a new coil, why would it not be blue?
I was also wondering if the plug wires I'm using are ok. They shoot 10K ohms less than the originals, but they fit. Is the lower resistance bad? I think it should be better.
