1979 Revenge V-22 Custom Twin 1996/97 155 Johnson OceanRunner Series

G&J,

For the last 3 seasons since I took ownership I have been running off external tanks and mixing manually. From what I gather the VRO pumps for the oil also are the fuel pumps. The VRO pumps are still on the engines and act as pumps from the external (or internal) tanks I have been utilizing. The boat is equipped with both of the original oil tanks, although I had the VRO lines disconnected and pugged at the motor as well as disconnected the auditory oil alarms as I know the fuel is mixed appropriately. I also disconnected the rev limiter system as it was still sensing oil shortage on my initial sea trial and the engines would not rev over +/-1500 RPM.

From what I gather the VRO side of the pumps is a VERY common failure which results in the loss of many a two stroke with oil injection from the 96-97 Johnson era, additionally the pumps are almost $500 each, wholesale, without installation. Bulk 2 stroke oil can be purchased in 5 gallon pails, so my thought/idea is to fill the tank to capacity, after pressure testing, with mixed fuel. I am still trying to come up with ideas, (and would love some input) as to how I will calculate how much oil to add before re-filling as the sending unit doesn't appear to work and the nuts attaching it to the aluminum tank are looking pretty crappy. Don't want to over or under mix, nor over fill the tank!

Any thoughts on that?

I was successful in pumping out the tank! I monitored what was coming out and in the end I had 1- 1&1/2 gal water, 4-5 gallons of mixed water/gas, then +/-17 gal of somewhat decent smelling old gas, before I reached the 6 gal I had mixed and added, came out nice and blue tint and smelled good. Everything was layered as one would expect after having the boat stationary over the winter allowing for adequate time for separation to occur. In any event I have eliminated +/- 140 lbs of weight, so if I do continue to just run external tanks I have at least lightened the load of fuel which has had uneven weight distribution in the stern (my aux tanks are under the rear bench seat and I also carried an additional 22 gallons in cans stored to the stern for a total aux capacity of 34 gal).

I am contemplating adding in 6 more gal of mixed fuel and pulling her around town on the trailer for a while to slosh it well, then pumping that out and implementing a two stage Raycore filter system to keep any foreign particles which may remain in the main tank from reaching the engines. An additional obstacle is the fact that I have the only Revenge I can find any info on that has an aluminum tank, so until it is filled, I have no idea what the capacity is. (I may be biting off more than I can chew with this whole operation but at least the tank will be flushed and empty!) Can't find the stencil # on this hull suggestions as to where to look?

Thoughts on that?

John, I found the same "foam" type padding near the sending unit and can see orange "spray" type foam at the stern end of the tank, under the hatch cover as I saw in your personal page pictures. At some point someone added a through hull port and starboard that drain from the stern most compartments into the "fish well". Gary from I believe CA, commented on the "Have you seen one like..." tread and has a shutterfly link to the restoration pictures of his 79 Revenge, his gas tank was sucked concave! (again a poly tank) Here's the link https://garys22revenge.shutterfly.com/ On WC he goes by steelhead55. He's done what appears to be a great restoration job on his boat!

It seems I am certainly putting a lot of effort a boat I am supposed to be selling! Ha Ha! Can anyone say Whaler addiction?!? ;o)

Would love to hear your thoughts and comments guys!
Jeff
