Wanted to take my ski out tomorrow but was not sure what the right oil mix was can anybody help me? it is a kawasaki 550sx stand up i dont know what year but its old. Old shape with round air intake on right hand side. I also want to know how much engine oil to put in it.
I also have a 1991 stand up 650 and that takes 50.1 and apperantly with really good oil i can run it closer to 60.1 is this correct?

for the 550 run it 40:1...and the 650's were atleast originally oil injection....this might have been bypassed so that you don't risk oil pump failure which could mess up the engine, this is very common on outboards with oil injection. I would NOT risk running at 60:1 as the oil in the gas is what lubricates the engine and with that little oil, could cause problems to the engine
