I have a 1983 Ski Nautique 2001 with a 351 Commander engine. It ran great until a few weeks ago. I tried putting a new coil, fuel filter and fuel pump on it and it is still doing the same thing. The boat came with a prestolite ignition that I converted to an electronic ignition with a conversion kit in 2008. The boat runs great for 5 or 10 minutes. Then it spits and hesitates sometimes dying. It has been idling fine all the time. Any advice would be greatly appreciated.

When it acts up, I would pull the coil wire out of the dizzy & hold next to a engine ground (bolt head). You want to see a big blue spark, not a yellow one. Its a good idea to wear gloves if you don't like the feel of 10,000 volts.
This will at least get you focused on fuel vs. ignition. |

SNobsessed,
I will check that and get back to you. I have one question. Could the problem be in the distributor? Thanks, |

Symptoms indicate it running out of gas.
Clean out the fuel pickup, and antisyphon valve. |

Thank you for the advice. I took the anti-siphon valve out. It looked clean. The fuel pickup line is welded into the tank. So I blew air into it with my air compressor. The boat ran great all weekend. I am just wondering if I will pick trash up again soon?
Thanks again for the help. |
