Quick question

[Jhayes780]

I just got a 1996 Johnson 115 hp ocean runner and need to know the fuel to oil mix ratio if anyone has it.

50::1. However, they came with OMS oil injection.

Weird I didn’t see it when I popped the lid. Where would it be? Also should I pre mix the gas until l know for sure the injector is working

 

[Chris1956]

Definitely premix until you are sure the injection is working. Look for an oil tank in the bilge.

The OMS (injection ) pump on under the airbox, in the front of the motor. It is a black round pump with a rectangular front. Look it on the crowleymarine web site. The OMS pump could be used to pump premix, so if the oil tank is missing and the pump is present that could be it.

Is there an oil tank anywhere? All OMS systems had a separate oil tank. Don't just assume because the pump is there the injection is hooked up

I can’t find one

Mix 50-1 then and make sure the oil nipple is plugged.
