rigga Posted September 21, 2013 Share Posted September 21, 2013 Hey fellow raiders.Just thought id ask here for some advice recently my 6 hp johnson motor has been playing up real bad. at first we thought it was a bad ratio of fuel to oil. but the next time we took it out, the same thing happened.issue: motor starts fine and runs well for about 10 seconds, then 75% of power is lost and it bursts out on random power levels. i noticed when i slowed down alot of water cameout of the head/cover part of the motor and would run again for another 10 seconds.Just wondering if anyone here can give me advice, would really be greatly appreciated,Rigga tight lines Link to comment Share on other sites More sharing options...

Jewdreamer Posted September 21, 2013 Share Posted September 21, 2013 If 2 stroke it could be fuel mixture running out the carb and the problem is a damaged reed valve... Link to comment Share on other sites More sharing options...
damian Posted September 21, 2013 Share Posted September 21, 2013 sound like the head gasket. take the spark plugs out and see if there wet after u have ran it. has it over heated recently and cut out? if so its a blown head gasket. Link to comment Share on other sites More sharing options...

Guest Aussie007 Posted October 1, 2013 Share Posted October 1, 2013 i doubt thats your original problem, the problem sounds like a worn needle and seat in the carby Link to comment Share on other sites More sharing options...

Please don't come back on here & complain when you take it to somebody else & they stuff it up! Cheers, Grant. Link to comment Share on other sites More sharing options...
