Boat engine problems- advice needed.

[rigga]

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,

If 2 stroke it could be fuel mixture running out the carb and the problem is a damaged reed valve...

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.

rigga are your spark plugs loose? can u take a picture of the leak and show us? could be anything really

i took to to a motor mechanic just to get it inspected. roughly said the arm rod needs to be replaced as its way to stiff! and water has got to the sealings round the head gasket.

if anybody knows a good mechanic inbox me please

i doubt thats your original problem, the problem sounds like a worn needle and seat in the carby

Craig at Huett Marine is the best in the business.

Please don't come back on here & complain when you take it to somebody else & they stuff it up!

Cheers,

Grant.
