I bought a boat with this motor on it a year ago, for next to nothing. I tried to fire it up with no avail. I checked for spark, and nothing. All the plugs were dead. I changed the coil, still the same thing. I don't know anything about boats really, "cept they float" and would appreciate any ideas would be great! I was told it was the power pack, (like the brain box or something) By the boat place near here! Quoted me $300.00 dollars for the replacement part. Hell I paid less than that for the boat! I just plan on selling the thing as I have a good running boat already. But I would still like to get it running before I sell it.
