HELP with Evinrude 50!!

Bought a new boat for the first time recently with a 50 hk Evinrude 73 or 74 year.<br />It run just fine on my first week but then it suddenly died.<br />Checked the sparks , changed it , no good.<br />Rebuild the fuel pump and the engine started.<br />Run a few laps and it suddenly died.<br />I can get it to start with gas but when i put the gear in it will die.<br />Today i noticed that one spark didnt got a bright so i changed the spark connector and tested , wow it run just fine so i tokk it for a ride and after 20 min it suddenly died again.<br />I have checked almost everything and this is driving me insane.<br />I was loooking forward to a nice holiday but nope.<br />Sorry for my bad English.<br />Does anyone have any clue?<br /><br />Regards / Nellie

Re: HELP with Evinrude 50!!

The clue you gave us:<br /><br /> "i changed the spark connector and tested , wow it run just fine"<br /><br />tells me that you need to get a new set of plug wires. Get the ones that are premade. They come with new connectors. Also stop at an electric supply or auto parts store and get a tube of dialectric. Put a dab on the end of each plug & coil before you attach the new wires. That helps give you a good electrial connection.

Re: HELP with Evinrude 50!!

I was down to the boat this morning and it started up just fine.<br />When i have the problem i cant put in a gear without the engine dies.<br />So my guess is that its just one cylinder running.<br />If i take a ride with boat now it will probably function well for a time and then lose power.<br />Tx 4 the quick answer i got.<br /><br />What do u mean when u say coil?<br />Can u explain that word since my english sucks
