Hi folks. I managed to get hold of a new tohatsu 9.8 2 stroke. I ran it in for a couple of hours then stored it in the garage. I just went to get it as I'm planning a trip with it and there is a little bit of oil leaking from somewhere near the propellor. I presume it is gear oil.
Any thoughts on what I should do?
Oh and there's no warranty by the way!
Cheers
My 4 stroke required an oil change after 10 hours - the running in service.
As it had so little use, i questioned whether such a short interval service was necessary and was assured it was as the oil that came with it was not standard spec and gearbox needed checking for abnormalities due to manufaccturing tolerances.
Not sure if it was gear oil or engine oil but assume by comments it was at least gearbox oil - in which case the short interval service may equally apply to a 2-stroke.
Maybe worth checking paperwork regarding initial service after running in period in which case it may be less abnormal and an adjustment made as part of the service or resolved by running normal gear oil.
Managed to speak to the chap I bought it from. He said it is unburnt engine oil which finds it's way out through the prop. He also said to expect a bit more than normal because I'm running it at 25:1 due to break in period. Seems like it's nothing to worry about.
Yep he's likely correct... you'll get this more at 25:1. If it was gear oil it would be a nice golden colour... I assume you are seeing quite black oil deposits.
That's good... just a normal stain from the thru prop exhaust then. The water part evaps off and you're left with 2-stroke oil residue which can look alarming.
Duggie,
Just to confirm what others have said, it's normal and just black 2 stroke oil residue leaching from the through prop exhaust. Get it on my 9.8 particularly if only run at low revs.
Enjoy your new motor.
