The older pumps idled between 150:1 (prior to 1990) and 100:1 (1990-1992), then richened up to 50:1 as the engine load increased. Other suggestions: Johnson/Evinrude VRO Fuel Pump Conversion. Parts ordered from this website may or may not be in dealer stock at the time of order. Resistor plugs are not the same thing and may be the source of problems. "My engine is hard starting at times, " says a fourth angler, "the VRO pump must be getting weak and the warning horn blows constantly whenever I run at full throttle on my 150. Re: Should I disable my VRO?
Even better, there's a new VRO (OMS) pump that can be used to upgrade all the previous years and model outboards. This arrangement offered several advantages: the operator did not have to compute and measure oil for pre-mixing in the fuel tank. It consists of four basic sections: Cutaway View of VRO Pump Showing Major Components. Changes are periodically added to the information herein.
Occasional checks should be performed to make sure the charging system, warning horn, and related parts are operational. I dont need this to fix to be "by the book", I need to get on the water and get use out of the boat and engine. They are calibrated for each model of pump. Since 1993, the VRO is actually called an oil metering system (OMS). Need up to 30 seconds to load. Can anyone help me get a part number? Some installations even had 5/16-inch fuel line squeezed down over the smaller fittings. ) You can also replace the clear plastic cap with the later model's solid black filler cap (OMC P/N 176217) that provides much better water intrusion resistance. Early systems had a smooth vinyl oil line that hardened after a few years and sometimes caused air leaks. By the way, the SystemCheck® can be adapted (with accessory kit P/N 176709) to any engine with a four-wire VRO pump. What standard pump can I use?
This article discusses the history of OMC outboards with VRO, the theory of VRO operation, and the diagnosis and repair of common problems. The VRO's electronic circuitry compares the RPM of the engine to the number of pressure pulses from the oil pump piston. I haven't done any of them (I bought the standard pump to do the job, but the motor was stolen before I got to replace it) so I cannot say first-hand what is correct or not. "Come to think of it, " the third member of the group chimes in, "my brother-in-law's offshore rig with twin outboards must have a flaky VRO; one motor always uses more oil than the other. Since the VRO depends on crankcase pulses to operate, it is susceptible to backfires from a lean running cylinder or an out of tune engine. If air gets into the fuel, it causes a foamy solution, similar to a head of beer in a tall glass. Guys, I have 1987 Ranger with a 1987 Johnson GT150 that I bought new. But I just dropped a cylinder and now am trying to find a good used 150 or 175 for the boat before I sell it. Over the years some engine failures caused by lack of proper lubrication have been mistakenly attributed to defective VRO components. Pump the fuel primer bulb until fuel exits that hose with the tint of whatever oil you used. I have a 1984 Evinrude GT150 and they disconnected the VRO but didn't put a fuel pump on it. Sharing buttons: Transcript.
In the mid-1980's outboard manufacturers began to offer oil mixing pumps which would blend lubricating oil from a separate reservoir tank with the gasoline as it was being pumped to the engine. I would like to replace the fuel pump with a regular pulse pump like I did on my 70hp. The quickest and easiest test is the grounding of the tan overheat temp switch wire to the engine block. You can convert the VRO pump into a straight fuel pump, eliminating the oil tank and VRO pump warning system, but retain the overheat warning setup by doing the following: 1 - Cut and plug the oil line at the engine so that the oil side of the VRO pump will not draw air into its system. Back then, no company had alarm systems for a pump failure or loss of oil flow. Since each carb receives the same oil to gas ratio, the VRO cannot cause only two cylinders to fail.
Moderated by banker-always fishing, chickenman, Derek 🐝, Duck_Hunter, Fish Killer, J-2, Jacob, Jons3825, JustWingem, Nocona Brian, Toon-Troller, Uncle Zeek, Weekender1. Changes included an electronic circuit to compare the oil pulses with the engine's RPM, a better oil pump piston, alcohol resistant seals, and a brown fuel outlet for recognition. A system with 3/8-inch fuel lines, a clean "spin on" filter, and a quality anti-siphon valve should show between 2. Since the VRO did not malfunction, there was no alarm to sound. The pin's movement is detected electronically and "counted. " Surely some of them must have a pump that would work for me. At idle and low throttle settings, the weaker crankcase pulses cause shorter piston movements, which in turn, pump less oil with each cycle.
Now you have richer gas oil mix with its resulting symptoms. The original VRO from 1984 and 1985 had a black fuel outlet fitting and no wiring. If you see any signs of contamination, the tank should be flushed clean, the filter (OMC P/N 174377) changed, and the oil line purged. Mastertech may make improvements to this site at any time. The warning horn should sound off. A long standing practice was to pre-mix the gasoline and oil together in the boat's fuel tank. Of course a steady tone at all speeds is an overheat condition. The crossflow V-6's have a pulse limiter with a fitting at each end and spliced in line with the VRO to crankcase hose. When the piston (dark green) nears the end of its travel, a small spring unloads a poppet valve located in the middle of the piston assembly. As you run out of fuel, the oil still pumps, filling the lines and carbs with your favorite TC-W3 lubricant. As the oil flows into the fuel area, the pressure moves a small piston that actuates a steel pin in the alarm module. Gasoline is drawn into the blue area of the chamber, travels through the piston's flapper valve, and is pressurized in the green section on the following stroke. The travel of the air motor pumps the fuel and the oil together to the carburetors and the alarm system monitors the oil pressure counts.
Again, you get the full shot of oil mixing with less gas. Each engine revolution moves the piston (dark green) incrementally to one side of the air motor chamber (tan) and compresses the large spring. It WILL lean out on the top end as loopers have very small crankcase pulses at higher RPM's. I just bought a new boat a month ago. The oil line should be OMC's 1/4-inch I. D. inner "rubber" hose (OMC P/N 333485) without any splices.
How to Remove and Replace a Johnson or Evinrude VRO oil Pump with a Direct Fuel Pump. Audio volume control bar. To simplify things just remember that the air motor converts the crankcase pulses to a back and forth motion. This information is disseminated in good faith, however MasterTech assumes NO LIABILITY whatsoever in regard to this service. I've found countless sites online selling fuel pumps and I have many local marine stores in my area. Each OMC (VRO) kit contains the parts needed including a new pulse limiter to install the system correctly. Trace the wires from the back of the VRO to its rubber plug (electrical plug) and disconnect it. When working on a fuel system, check for any restrictions or air leaks which would affect the engine. Replace the VRO fuel pump with a simple fuel only pump. Public perception fed by uneducated mechanics put the blame for almost every engine problem on the VRO. Thank you for reading.
