oily residue coming out of the lower weep hole

ok i fired my 2 stroke mariner up and have noticed some oily residue coming out of the lower weep hole , i `m thinking i will have to check for water colour as a seal may have gone ,

it could also be i run my fuel on about a 50-1 rather than the 100-1 ... it`s not much oil but its only been ran in my weely bin

does anyone else get this problem or is it a major must sort now ?

I would have thought it would be worth running it on the correct fuel / oil ratio and give it a proper run on the boat to clear it out and then see what it is doing. Chugging in a wheelie bin with too much oil in the mix wont give you an accurate scenario.

If it was winterized it will probaly be the special fogging oil coming out ,if so that is normal but as an aside I would not run any 2/str on a 100.1 mix always 50.1

Probably 2 stroke residue. it's the wrong colour for gearbox oil.
