I took my boat out a few weeks ago and it was running real rough, would not get up to speed and sounded like it was not running on all 4 cyl. So I took it back to the marina, there were 2 wet plugs that were not firing, they changed a coil, and cleaned out the injectors. THey said the gas I left in from the winter was bad and I should have not left it was a full tank. They said they took it out and ran it up to speed and I should be fine. <br /><br />So I take it back out last week, it idels out of the marina fine, bring it up to speed and runs fine for a few minutes then starts to die and stalls. After that it would not run for more then a few seconds. Had to paddle back to the marina. Now they say that the whole fuel system could be pluged up.<br /><br />Should I try a gas heat solution to try and get the crap out of the gas, get all of the gas out of the tanks 30 gallons, any other suggestions??? I am not apposed to taking it back to the boat shop, it is just a commute for me.<br /><br />thanks in adavnce<br /><br />Doug
