VRO Upgrade? Dhadley,others

[rloper]

I have read in some of the previous post of a constant 50:1 ratio pump from evinrude(omc?) and would like to know more. Such as probable price, is it a direct replacement for the vro? I really like the vro just got to point I didn't trust it. I have a four stroke kicker motor and like the idea of being able to use same tank for both. <br /> Thanks Fellows<br /> Rick<br /> Dreaming of snapper season already!

The VRO has pumped 50/1 starting 1989. One of the magazines claimed 60/1 for later models, but I have not seen anything from OMC about the 60/1 and I have a set of SBs to Dec 1999. Someone else may know more about this.

Well, I can tell you what I know. I have a 1989 V-8 (requires two pumps), My motor came with VRO. On 8-98 I purchased new pumps for 134.00 a piece. The new pumps required that I replace the pulse limiters, with new ones (included) they are a blue anodized color.<br /><br />As I remember, I did not have a choice as to VRO or non-VRO as the 50:1 is the current replacement for the pump. My common sense tells me, that after many years of refinement that this should be a very dependable version.<br /><br />Now, to confuse the issue a little bit. Now that Bombardier is taking over, will they make further refinements? <br /><br />I also understand that a group of OMC engineers started their own business as the OMC was going bankrupt, apparently they go the extra mile with these pumps, make some improvments and rigorously test each one. Possibly these would be the type of improvements that Bombardier will make.<br /><br />My personal belief is that the current version is a good one, and improvements to this pump seem minor (read for yourself) http://www.dfitechnologies.com./ Most importantly, confirm proper operation of the pump once you install it. Good Luck
