  • Johnson 225 VRO

    Has anyone had any experience with this Motor ? This boat is new to me and since the tank is bad Im trying to test run the motor off a 6Gal remote tank . I would like too by-pass the VRO completely and go with a Pre-Mix so I have less of a chance of burning up the motor . Any Ideas?[][][]

    Replace the entire fuel pump with a nonVRO pump. They are on ebay for $300ish.

    You can also run 150:1 mix fuel and leave the VRO in place. This will give you extra protection just in case it does fail. Extra oil never hurts. Also I have the same engine and have run for years on Walmart Supertech oil for $12.88 per gallon. Boating is expensive enough no need to waste money on more expensive oil that works.

    Just my 2 cents

      Depending on the year of your Johnson, you likely have an OMS (later incarnation of what people call the VRO).

      Very reliable system, not prone to failure.

      I'd leave it; premix doesnt hurt per se, but it does contribute to carbon build up through over-oiling, especially at idle.

        I remove the VRO pumps and install an electric pump in its place. 40 bucks. Use the purple and black wire from the VRO to power the pump. Bonus is it self primes without needing to use the primer ball. Been successful on dozens of engines over the last 20 years

            I have ran Johnson outboards with a Holley red fuel pump/bypass regulator with return line and VRO pumps. If your running a V6 the single VRO pump is pretty simple. I also had a 300 Johnson V8 with dual VRO pumps and 1 VRO went bad, fuel side of pump. It was less money to eliminate both VRO pumps and run a Holley red fuel pump and regulator with premix than to replace 2 VRO pumps. I like the VRO on my 250 Johnson V6, changes the amount of oil at idle vs full throttle and helps to not foul plugs nearly as much trolling. The VRO pump gets a bad rap by mechanics who don't know how to work on them. But there always willing to sell you a new one.[]

              My last boat had a 200 johnson vro. It was a 1993. The service tech talked me into disabling the vro pump and premixing. It was nice knowing e oil was in the fuel, but you could clear the mosquitos out of a canal on a cold start and it loaded the plugs pretty bad. Always was clearing it out before planing after a long idle. Great motor. If it runs with the vro, keep it.

                Sooo how do I go about this on my 175 hp. Its having hard start issues due to heat soak after running.

                I have heard of people doing this but some mention risk of fire???

                  YOUR heat soak problem could be from ethanol fuel alcohol boils at a lower temp than straight gas I am told....

                  Plug the hose that goes to the block, remove the pump, and the oil lines going to it. Put the electric pump inline with the fuel line and the carb (or vst tank in your case) use the purple wire and the black wire to feed the pump. Purple is 12 volts when ignition is on....
