Re: Buying Yamaha 6hp 2 stroke two cylinder - anything to watch for?
Verify the lower unit oil is up to snuff... Two strokes do not require that the engine oil be changed, so many people forget about the lower end.
I would simply run the engine in gear for a min., then open the fill hole, poke a Q tip in, and take out a small sample. If you get brown mayo, that's bad. Metal flakes would be bad too. Dark brown/black stinky oil is good.
