I have a 2001 Johnson 90HP I am getting alot of oil out of my exhaust at idle. Once the rpms increase the oil clears up but once the rpms lower back down the oil is back and the engine stalls out. It seems like the oil pump is pumping 100% all the time and its flooding the cylinders with oil at low rpms when it can't burn it off. I have read of people just bypassing the auto injection oil system and premixing. I am not sure about trying this on my engine since I believe the oil is injected right in to the cylinder?? I thought the oil was injected into the carbs but after reading the SELCO manual it looks like it is not injected into the carb. Does anyone have experience with this problem??

Re: Oil dumping out of exhaust at idle

Not sure about the oil coming out of the engine.(oil pump maybe) But premix would be ok for your engine. Mixed at 50:1 Little smoke at start up but other than that it will be fine. The oil will still make it into the cylinders because its in the fuel. In my opinion I never liked oil injection. The newer ones are more reliable than the older ones. I just like to make sure its there by premix. Remember now this is just my opinion on the oil injection.

What about the no oil warning system? I assume this will have to be disabled if I do a premix?
