Having problems starting my outboard. I recently replaced the brushes on my starter motor which curred the lag i was experiencing but now i can't start it. I have checked that there is power to the plugs which are sparking, so must be fuel related, i had the carbs flushed 2 weeks ago after i ran out of petrol but since then it won't start. I can smell petrol but that's it. Does anybody have any ideas??<br />Also one thing i noticed was that, then turing over the engine that one of the wires under the starter motor was starting to smoke. It was red and then ran to the bottom of what looks like 2 switches positioned on the frame. I assume this was because i was tring to start it for a few minutes, is it something to worry about or should i replace something.<br /><br />Any help is appreciated.

There's a backfeed problem which usually means a bad ground or incorrect wiring. Check for good grounds first. Also check for pinched wires.

A smoking wire IS something to worry about. I wouldn't take it out until you find out why. Check all the connections and make sure they are tight. Check your fuel pump, the diaphram may have went when it was trying to pump air. The kits are cheap.

those motors need lots of fuel to start, try squirting some fuel directly in the throats of the carbs, and THEN try staring it( do not use starting fluid)<br /><br />that red wire you saw goes from the starter to our selenoid, which is basically a big switch that tells your motor "when"to start, or when to apply voltage top your starter.<br /><br />take the cable off the starter and clean the ends with sand paper or wire brush, do this on the battery also, and also on the selenoid and on the big black ground wires.....<br /><br />oh yeah, get one of these....<br /><br />mikey third one down.... <br /><br /><br />m ikey
