Black Frothy Liquid

[nosliw]

Hey Raiders,

Recently I got a whole heap of braid tangled around my prop and havent got around to getting it looked at yet as I have been busy.

I have removed the braid and re attached the prop and l I decided to start up my motor as I havent started it up in such a long time. Left it running for about 10 mins and went back in the house. I came out about an 20 mins later and to my horror I saw this black oily frothy liquid dripping from where the prop goes(Video).

Any ideas as to what may have happend ? I'm fearing for the worst..

If it is a 2 stroke they often get a build up of oil from low rev ildling and in a bucket it will froth up. Having the motor tilted up can also mean a larger build up of oil. You can normally smell the difference between oil in the gearbox compared to 2 stroke oil. You may have a oil injection system that is over oiling. How is your oil / fuel consumption? Same as usual?. If it is premix the oil may have settled to bottom of tank if it wasn't shaken and given your motor an extra dose. If motors don't get up to operating temp they don't burn the oil off properly.

I'd remove that prop and observe just where it is coming from. If it is around the shaft it will be gearbox oil and you will need it looked at.

I would check your gearbox oil and make sure there is no water in it ( ie it isn't white and frothy). If it is you will need to get the seal fixed. Just remove / partially unscrew the top screw bung and look at the level and also the colour. Should look clear not milky.

Previous post covered the gearbox stuff in more detail.

Hi, that is excess 2-stroke oil due to possible few reasons. Lack of use / low speed running like you would of done on the flusher / cheap oil (very likely) / engine running cold at idle and not reaching temp (also very likely and you should check and service thermostats).

Also preventative maitance would suggest to drain and refill the gearbox oil and just confirm no water entry.

Cheers,
