1. I took out my boat today and noticed on one occasion that the tell tale was blowing smoke momentarily then water, is this normal?<br />2. Also what should the fuel mixture be? I was told it should be 50:1 with 2 cycle oil<br />3. Spark plugs and Fuel filter, how often should these be replaced?<br /><br />Any help would be appreciated!<br />Thanks!

thats normal 2 strokes will smoke it uusuallt takes 10 or 15 seconds for the water to run out. it is 50 to 1. check the plugs. replace them anyway cant go wrong they are cheap .
