So my boat wouldn't start and I decided to take my boat to the mechanic to have a Pro look at it. He said the compression was good, but the engine has no spark, then went on to explain what spark was and that the Electric Distributor Body or Trigger is bad and needs to be replaced. He said it's an electrical problem. Does anyone know what this is? I'm clueless to repairing engines.<br /><br />The mechanic said the part alone is $412 and is difficult to install, so the labor will be $400! Does anyone know if it's truely hard to replace yourself? I have the engine manual, so I was thinking of looking up the part in the book. Does this estimate sound about right? Anyone else had a similar problem with this part or engine? <br /><br />I'm a new boater and have only had this boat out 3 times in the last 2 years. Any opinions, tips, suggestions or help is much appreciated! Thanks in advance!<br /><br />Brian
